The computer does not see the microsd card. Why the phone does not see the sd memory card or usb flash drive. What to do? Software error that caused the phone to stop seeing the memory card

The computer does not see the USB flash drive - there is a solution.

Hello. Your the computer does not see the USB flash drive , memory card or hard drive and you are wondering what to do? Surely every computer user has a similar situation, or even more than one.

Today I will help you with this question. I'll tell you what problems there are with displaying usb devices and the possibilities of solving them. By the way, the last article was about data recovery from a USB flash drive. If you are interested, then replenish the baggage of your knowledge.

Your computer does not see or does not detect a USB flash drive, hard drive and memory card. Let's look at the possible reasons for this situation. At the end of the article, do not forget to watch a visual video lesson on how to make a flash drive or hard drive work.

Determine the device

The first step is to determine exactly how the computer does not see your usb drive. From this answer, it will be clear whether it is possible to recover data from a flash drive or not.

To do this, go to the Windows Device Manager.

In order to enter it, you need to right-click on the shortcut of my computer on the desktop or in the start menu, go to properties, click on the device manager.

Then select disk devices.

We got to the device manager and the disk devices tab. If your flash drive or memory card is displayed in this list, then with a high probability you can recover data on them. If the flash drive is not there, then most likely the memory card controller has burned out. I recommend trying to connect your usb device to other computers.

If nothing changes and the flash drive is also not visible, then most likely the matter is in the faulty controller. From such a usb device, you will get the data out, you can of course contact special institutions that are engaged in this (they are not in all cities), but they will charge you a tidy sum for the work. So think about whether you need it or not.

Your flash drive is visible as a device, but it does not appear in my computer or explorer, or asks to be formatted. To do this, you need to go to disk management. To get into it, you need to follow these steps. Here are screenshots for clarity:

The device is displayed, writes its volume and file system - it is ready to work and functions normally.

The device is displayed, shows its size, but does not display the file system and writes "not defined". In order to use it, you need to right-click in the undefined window and select format. You can check the quick format checkbox and click OK. After the device is formatted, it should work normally.

Displays as a removable device, writes no media, and does not show the file system. All these parameters indicate that this device is not working properly, there are internal or external damage to the controller. With such a flash drive, you can read information without special expensive equipment.

Power indicator

When connecting a flash drive to a computer, a small indicator on the usb device should light up. If it caught fire and started blinking, then everything is fine with the flash drive, but not with the operating system, you need to look for the reason in it. If the flash drive indicator does not light up, then the problem may be in the device itself or in the connected port of the computer.

Front usb ports

There have been cases when a USB flash drive is connected to a computer via the front usb ports, but the flash drive does not work. Perhaps these front usb are turned off or forgot to connect them to the motherboard.

Not enough power

Power shortages mainly occur when connecting hard drives through the front USB ports of a computer, hubs and hubs. It is best to connect such devices directly to the usb connectors on the motherboard, that is, on the back of the computer. If you are using a usb hub or hub, then disconnect unnecessary devices, maybe this will help. Also, the reason may be in a low-power computer power supply.

Usb disabled in BIOS

This problem is rare. Mostly in computer clubs and similar entertainment venues. What is it for? So that a person does not introduce viruses and download various programs and unnecessary information on the computer. It is rather a protective measure. If this is a home computer, then you need to go to the BIOS settings and check the box to enable the launch of usb devices in the motherboard.

USB device not recognized

The usb device is not recognized, and when a USB flash drive is connected, the operating system gives it an already used letter (the used volume label). This does not always happen, there are other cases. In order to fix this, you need to go to the computer control panel.

I showed how to enter it above, or you can call the Run window - the keyboard shortcut on the Win + R keyboard (the checkbox between Ctrl and Alt plus the letter R) and type the command diskmgmt.msc. Go to disk management, find the device you need - a USB flash drive, right-click on it and select Change drive letter or path to disk. In the window that appears, you can add or change this letter.

Outdated drivers

It is possible that you have outdated drivers - update them. To do this, you need to find out which company is the manufacturer and model of your motherboard. Usually written on the box with the packaging, if you saved them of course. If not, use Everest or Aida. With the help of them, you can find out the model of your motherboard and a lot of other useful information about your computer. After you have found out everything, you need to go to the manufacturer's official website, find the required motherboard and download drivers for the chipset and usb device, if any.

Viruses

There have been cases when the computer does not recognize the USB flash drive due to viruses that have appeared in your operating system. To do this, I recommend using good antivirus programs and doing a full virus scan at least once a month. If you do not have it, you can use the free antivirus Kaspersky Yandex version, or purchase a paid product.

Different file systems

This is common, but very rare. Your computer does not see the USB flash drive due to a conflict between the file systems of the computer and the USB flash drive. Most flash drives work in two file systems FAT and FAT32, and hard drives in NTFS.

You can try to format your flash drive in another format such as FAT32 or NTFS. Perhaps after that everything will work fine.

Helpful information. On a USB flash drive in FAT and FAT32 format, you can upload information in one file no more than 4 Gigabytes, and much more on the hard drive. Therefore, if you encounter such a problem, be prepared for this and keep in mind.

And for dessert, watch a short video tutorial on how to make the computer see a USB flash drive and a hard drive. For a comfortable and enjoyable viewing, I recommend watching this video in full screen, that is, in full screen mode.

The computer does not see the USB flash drive and hard drive

Over the past few years, flash storage media have become very popular and are used by us, literally, every day, due to their advantages over disk media. It is hardly possible to overestimate its usefulness of a flash drive, because you can quickly write information or read it on it, it does not take up much space in a portfolio or bag, and the price segment is pleasantly pleasing.

Despite all the positive aspects, sometimes there are situations when the data cannot be read due to the flash drive itself or the computer. Indeed, at the most important moment, you can lose access to the stored files, and in order to quickly return everything to normal, you need to have certain knowledge. In this article, we will analyze all possible problem situations and find ways to solve why the computer does not see the USB flash drive.

The most common problems why the computer does not see the USB flash drive:

The flash drive itself does not work

This is the worst scenario for a person whose documents are stored on a USB flash drive, because it is practically impossible to bring it back to life. It is possible to disable a USB flash drive by mechanical impact on the device chip or its controller, by shorting the electrical circuit, or by damaging the contacts on the USB board. This is what a USB flash drive looks like after the electrical circuit is closed or moisture gets inside the drive.

Determining if this happened to your drive is easy enough. The very first thing you need to do is check the USB flash drive for mechanical damage, chips, cracks, etc. If it is completely broken, you can look for a replacement at a computer peripheral store. If you doubt its inoperability, you can check it with a practical method.

Connect the USB flash drive to the USB connector of the computer, if the LED on it lights up and on the computer you hear a sound that is typical for connecting a new device, then everything is in order, it makes sense to look for the problem further. If this does not happen, most likely the flash drive is no longer usable.

You can try to take the flash drive to the service center, where the wizard will try to rewire the contacts or replace the controller, but it will be very expensive, and this action will be justified only if you have important documents on it. If no fatal malfunction was detected and the flash drive shows signs of life, try the methods to restore its performance, which will be described below.

The USB port on the front of the computer is de-energized

This problem is very common among desktop PC users. Most computer owners are accustomed to plugging a USB stick into the front USB ports because it's quick and easy.

But there is a situation when, during the assembly of the PC, for some reason, the front panel is not connected to the power system, usually this happens due to the forgetfulness of the computer master. Accordingly, your flash drive will not be displayed, despite its complete serviceability.

This problem can be solved in two ways. If you urgently need to use the information on removable media, you can plug it into the back of your computer. The front connectors will still be inoperative, but you will get access to the documents. It is impossible to call such manipulations a full-fledged solution, so we will consider the second option.

Method # 2 involves connecting the power cable on the motherboard to the front panel of the computer. The connection connectors may differ depending on the model of the computer case. But do not be scared, they all have markings and you will not be able to connect the wrong connector due to design features. The most common wires are VCC, D-, D + and GND. Moreover, the color coding of the cable and the connector on the motherboard is the same, but it is better to keep the reference by the inscriptions.

The first step is to gain access to the motherboard, to do this, unscrew the mounting bolts on the case and remove the cover. Find the cable that leads to the bezel and locate the same connector on the motherboard. In the image below, you can see what the connector should look like.

It is not recommended to make the connection yourself, it is better to call the wizard. If you connect the cable and connector incorrectly, you can burn these contacts and even devices. If you decide to connect the front USB connectors, then it is better to tell us the model of your case and motherboard, and we will show you how to do it correctly and explain what the connector and cable look like.

Faulty or disconnected USB port on the computer

Sometimes the problem of unreadable information on removable media is associated not with the problem of the flash drive itself, but with the connector into which it is connected. A certain USB port may be inoperative, and this condition can be caused by trivial damage to the connector pins. Then, not only a flash drive, but also other USB devices will not work in this port.

This problem can be solved by armed with an ordinary soldering iron and minimal knowledge of circuitry. If there is no such knowledge, skill and equipment, then this can be fixed at the nearest service center for a low fee.

However, if no reaction to the connection of a USB device is observed on all connectors, then the problem may lie deeper. Ports can be disabled in BIOS settings.

In order to connect ports in the BIOS menu, you need to get there initially. To enter the BIOS in the first seconds of booting the computer, you need to press the corresponding key on the keyboard, which is responsible for calling up the menu. Most often, the F2 or Del key is set by default, but depending on the company of the motherboard and the BIOS version, it may be different. In the first image that pops up when loading it is indicated.

After you have entered the BIOS itself, we need to go along the following route: “”.

Find the line “USB Controller” so that you are allowed to use the ports, opposite should be the value “Enabled”.

After you have enabled the USB ports on your computer, press the F10 key. This will save the settings you made and exit the BIOS.

The USB connector of the flash drive is dirty

A flash drive is a mobile storage device and therefore is often carried in pockets, briefcases, or as a key fob. Due to such operating conditions, dust and small debris can accumulate in the connector. This does not happen often, but it can cause the flash drive to malfunction. Dust and debris build up on the contact and prevent connections from the contacts in the port on the computer. Such a flash drive may not only not be displayed at all, but also freeze, slowly transmit or read information and not be detected the first time.

To clean the USB connector of a flash drive, arm yourself with a match and a cotton swab. Using a match, remove all debris from the connector, and then moisten a cotton swab with alcohol and wipe the contacts of the flash drive. This will help keep it free of debris and oxidation.

Infection with viruses

Nowadays, the issue of the security of the storage device is becoming more and more urgent, because viruses are in full swing. You can visit your usual social networking site on the Internet and get infected, not to mention downloading files from unverified sources.

Modern computer viruses can also multiply, no matter how strange it sounds. They infect files on your USB flash drive or computer hard drive, and their number grows exponentially.

Very often, the problem of the inoperability of a flash drive is a virus infection. The drive is detected by the system, you can hear the characteristic sound of connecting the device to the system, but when you try to read the information, you will see the message "" or " Application not found».

Before solving this problem, it is worth installing antivirus software on your computer and conducting a complete diagnosis of the files. To access the data on the drive, we need to delete the file with the virus and scan it. To do this, go to the "Start" menu and enter the following phrase "" in the search line.

Click on the found element with the left mouse button. You will see a window with the name "Folder Options" open, here you need to do the following:

• Uncheck the " Hide protected system files»
• Check the box ""

After that, be sure to press the "Apply" button and only after that "OK", otherwise the changes will not take effect. It should look like this.

After that, go to "My Computer" and go to the folder of the drive itself. There you will see the "Autorun" file, you need to delete it, and check the USB flash drive for viruses with one of the free antiviruses, the Dr.WEB Cure It utility can handle it perfectly.

Now you can fully use the USB flash drive and no problems should arise. If nothing has changed, then the problem lies in the absence of drivers, we will analyze it below.

Driver failure or outdated drivers

A very common problem is when the computer does not want to display a USB flash drive due to outdated drivers or their system failure. The failure can occur due to a power surge or an unexpected shutdown of the operating system. Or, older computer models may not work with 32GB or larger drives. We can say one thing, the problem is solved only by updating the drivers.

The first step is to go to "". This can be done in several ways, for example, through "My Computer" or find this section in the system search, as we will do.

We go into this menu, after which we connect the flash drive to the computer, and then open the “USB Controllers” sub-tab. Select the line “ Memory device", Click the right mouse button to open the system menu and click" Delete ".

Such manipulations allow you to remove the driver installed on the system for your storage device. As soon as you remove it, feel free to remove the USB flash drive from your computer and reconnect it. Then the driver on the flash drive will be reinstalled and the problem will be solved.

If the problem persists, it may be necessary to update the driver of all USB chipsets, this is quite easy to do. You can use a special disk that came with the motherboard, it contains all the necessary drivers. If you do not have it, download the DriverPack program, it will automatically select all drivers for which there is an update and will carry out this procedure after your agreement.

Moreover, most users have doubts about the correctness of their actions when they learn about the different USB formats. Don't be scared!

Drivers for USB 2.0 and USB 3.0 are installed according to the same principle. And the only difference between the ports is the maximum speed of reading and writing information.

Filesystem errors

The computer may also not detect your flash device due to file system errors. Let's check if this is so, go to "", as described above. Now you need to open the sub-tab “ Disk devices", If you see your USB flash drive there, it means it is working properly, and the file system does not perceive it as it should, and, accordingly, does not display it in the explorer. In my case, the flash drive was displayed, which means it is working properly.

To fix this problem, you must format your flash drive, but this action has several nuances, so we will consider this process in the next paragraph of the article.

If you do not see your drive there, then the problem lies in the malfunction of the flash drive itself, which means either the controller has burned out or the contact is unsoldered. Experts in service centers can try to bring it back to life. However, this is an expensive undertaking, it is easier to buy a new one, of course, if important information was not recorded on the faulty one and you need to restore the data on the USB flash drive.

File system conflict

Quite often, the contents of a flash drive are not displayed due to a conflict between file systems on the computer and the removable media itself. For example, if the computer operates on the NTFS file system and FAT32 is used on the flash drive, a conflict situation is possible. Moreover, this problem is common not only in Windows, but also in Mac OS. For example, if you format a USB flash drive on your Mac device to the ExFAT system or the standard MacBook file system, then the flash drive is unlikely to be read on Windows devices.

The very first thing to do is to find a computer where a different file system is used, open the USB flash drive and save the information that is important to you, because after formatting it will be lost.

To solve this problem, we need to carry out the process of formatting the flash drive. First you need to find out which file system is used on your computer. Go to "My Computer", right-click on the hard drive, open the submenu and select "Properties" in it.

In the window that opens, you will see information about the free and used amount of disk space, as well as find out which file system is used. In my case, the NTFS system is used.

After you know the file system of the computer, we need to format the flash drive to the same system. To do this, right-click on the flash drive and open the "Format" tab.

In the tab that opens, select the file system into which we will format, put a tick in front of the "Fast" attribute and click "Start".

A few words about why we are using the Fast attribute. Firstly, the formatting of the flash drive will be much faster. But there is also another side of the coin. If there were any documents on the flash drive, then only with a quick format can you recover this data using special utilities. If you have not checked the box, then the information that was on the flash drive will be lost for you forever.

The flash drive is not formatted

A fairly common problem is when you insert a USB flash drive into your computer (basically this is a new USB flash drive and its first use), and the operating system gives you a warning, which says that the removable disk needs to be formatted before use. And if the flash drive was used earlier and data is recorded on it, then you will not be able to access them. Moreover, the volume of the flash drive becomes 0, i.e. as if there was nothing there at all, not even a drive.

If you have already used a USB flash drive and this is not its first connection, then try connecting it to another computer, perhaps the problem will go away and you can save the data. But in any case, the flash drive must be formatted. How to do this was discussed in detail in the section "Conflict of file systems".

But I want to draw your attention to two points. So that after formatting there are no problems with the file system (FS), find out which FS is used on the computer and install the same for the drive. And second, if the flash drive had the information you need, then be sure to use the "Fast" attribute, so the formatting of the flash drive will only go through the table of contents, and the lost information can be returned using special utilities.

A problem with a partition or a USB flash drive is automatically assigned a busy letter

There are situations when the operating system incorrectly detects your removable media. It seems that everything is fine, the device connection is highlighted and the flash drive icon appears in the tray, but you cannot use it for its intended purpose.

The problem may be that the system did not assign the partition a letter under which the removable drive will appear, or it assigned it, but this letter is already taken, and because of this, an address conflict is obtained.

The solution to this problem will be the forced assignment of the partition letter that we choose, everything happens in manual mode. So let's get started.

The first step is to hold down the key combination "Win + R", a window with the name "Run" will open in front of you.

In the line we need to enter a simple command diskmgmt.msc, which will transfer us to the disk and storage management section.

In the opened storage media manager, we need to define our USB device. This can be done simply, disconnect the USB flash drive and reconnect it, the partition that first disappears and then appears is what we need.

In my case, the flash drive is a drive named "20151114_17", you can also identify it by a special icon. Now you need to click on it with the right mouse button, and in the menu that opens, select the item "Change letter".

Now another additional window, smaller, will open in front of us. In it you need to click on the "Change" and "OK" button.

Now another auxiliary window will open, where you must select any letter of the English alphabet, and after clicking on the "Ok" button, the letter will be assigned to the section.

It is worth paying attention to one important point! When choosing the letter to be assigned to the partition of your flash drive, look at which letters are already used by the system. This is very important, because we may not fix the problem, but leave it. This will happen if, for example, you designate a flash drive partition through the letter “D”, which is already assigned to the local disk.

Power supply malfunction or excessive overcurrent of the USB port

This problem is very common in our time. The fact is that the computer may simply not see the USB flash drive due to a faulty power supply. Let's figure it out in order, the power supply consumes electrical energy from the network, and then converts and distributes it to all nodes of the computer. It has a power limit, for example, a 400W power supply will not be able to give you 600W. This means that the consumption of the entire system must be balanced.

Such a problem may appear if you have recently replaced some important node in the system, let it be a processor. Now it consumes much more energy, in comparison with the past, which means that it simply does not reach somewhere, and in this case, this “somewhere” is the USB network of the computer. Accordingly, the power consumption parameter must be calculated in advance, and if such a situation has already occurred, you will have to replace the power supply unit with a more powerful one.

Moreover, the problem may lie in a malfunction of the power supply, it can produce much lower power potential than it was stated and than it did before. You will not be able to solve such a problem, since you risk the performance of the entire computer. The only solution would be to replace the power supply.

There is one more feature of this issue. Recently, USB devices for computers have become very common, for example, now such devices are powered: a mat for heating a cup, a table lamp, a wireless mouse, a removable hard drive, and in addition, a smartphone is also on charge. And you still want to connect a USB flash drive, but bad luck, the computer sees it. The fact is that there was an overcurrent on the USB ports. Those. all your devices already consume the maximum amount of current and you will not be able to connect another one. Therefore, in order to use a USB flash drive, you need to disconnect several devices from the USB ports of the computer and then the problem will disappear.

If the computer does not see the USB flash drive in Windows XP

There are many reasons why a flash drive may not be detected in Windows XP. Moreover, the problem may lie both in the operating system itself, and in the malfunction of the flash, and even in the computer hardware.

If the problem is related to the operating system, then it can be eliminated only by making additional changes in the settings; it is best to do this in manual mode, despite the abundance of special utilities that can help in this matter.

However, if the drive itself is faulty, then the only thing that remains for you is to try to save the data recorded on it. And after that, purchase a new and more reliable device.

If your computer cannot identify the USB flash drive, then it notifies the user with the following signals:

• Your flash drive is inserted, and you are trying to access the data on it, the message "Insert disc" pops up.
• The system notifies about the mandatory formatting of the drive for further use.
• Errors about the impossibility of gaining access to data pop up.
• The system may freeze as soon as you plug the USB flash drive into the USB port of your computer.

In this section, we will consider all the most common reasons for the non-functionality of a flash drive in Windows XP and give practical recommendations for solving them. Carefully read the description of the problem, if it is not similar to yours or its solution did not help you, proceed to the next step until the problem goes away. The first thing to do is to try to determine if the flash drive is working properly. This is indicated by a light indicator located on it. If you connected a drive and it blinks or is on, then the flash drive is working and the problem lies either in the system or in the hardware of the computer.

Try changing the port to which you connect the flash drive or even the computer, perhaps only the port or the entire system is faulty, and the flash drive will work properly on another PC. For example, if, when you connect a flash drive to a port, you observe a complete system freeze, this means that this port is faulty and it is better not to use it.

If you are using USB hubs or extension cords and the flash drive is not displayed, perhaps the problem lies in the device itself, and not the flash drive. If this turns out to be the case, you can take the hub to a service center or try to repair it yourself. To do this, you need a soldering iron, solder and a little experience, because most often you just need to solder one or two contacts and everything will work as expected.

Perhaps the problem lies in the lack of electrical current in the USB port system. To check this, you need to disconnect all USB devices on the computer (camera, printer, lamp, etc.), leave only the keyboard and mouse. If, after such manipulations, the flash drive appears in the system and you can access it, then the problem lies in a weak power supply. This problem can be solved only by replacing the power supply with a more powerful one, but the use of a USB hub with its own power source will help to delay the purchase of a power supply.

However, if the problem has not been resolved after disconnecting all other devices, the problem with a lack of power supply and an outdated USB port may still be relevant. In other words, on older laptops, you won't be able to open a 36GB or larger flash drive. There will be no way to solve the problem, you can only buy a more modern laptop or computer.

A very common situation is when a user plugs a USB flash drive into the front port of a PC, but the system does not see it. This means that either the ports are not connected to the power supply on the motherboard, or too little power is allocated to them. You can connect the front panel yourself, using the instructions located above in the section of the same name.

Doesn't see the USB flash drive due to Windows XP errors. Troubleshooting

The flash drive may also not be detected due to operating system errors. For example, Windows XP SP2 lacks updates and software packages that ensure the normal operation of USB devices. Moreover, a situation is possible when only a few USB devices can work in one port.

The solution to this issue will be to upgrade the system to SP3 and install the necessary updates. Even a new user can do this, since we only need a couple of clicks, and the system will automatically download, install and launch the update. So, let's get started, we can move in two ways - this is the official download from Windows Update or installing SP3 from a disk or flash drive. The first step is to check which package you already have installed.

Click on the "My Computer" icon with the right mouse button and select "Properties". The following window will open in front of you, where information about your system will be indicated.

To install SP3, we need to allow the operating system to search and update the computer system. To do this, just go from Control Panel to Windows Update.

As soon as you do this, the system will start searching for updates, after which it will offer you to update everything at once or select only the ones you need. If you do not understand what update, what changes, then it is better to let the system update completely.

After downloading all updates, the operating system will require you to restart your computer to apply the new settings. Click "OK" and wait patiently. That's all, now you can connect a USB flash drive and use it.

If you decide to choose the updates that should be installed, rather than downloading them all in automatic mode, then here is a guideline for you that will help improve the perception of USB drives by the system.

Driver conflicts in Windows XP

There is also a problem of driver conflict. The fact is that some already outdated drivers can cause errors at the system level; moreover, they can interfere with the normal operation of new drivers. A striking example of such a problem is a situation when a user inserts a USB flash drive into a computer, tries to access data on it, and the system immediately knocks out an error message asking to insert a disc. Or, the system simply freezes, and even assigning an existing letter to a flash drive partition is real.

The reason for these errors is as follows. Let's say you have two flash drives, you connected one of them to the system. In automatic mode, all the necessary drivers for this device are immediately installed. You did the necessary manipulations to write or read files and pulled out the drive. After that, you insert a second USB flash drive, which is completely functional, and one of the above errors pops up. This means that the system is trying to use the already installed driver from the first flash drive to run the second, but they are not compatible.

Reinstalling Windows XP USB Drivers

This problem can be easily fixed in several ways. Reinstalling drivers in automatic mode or manual. Let's analyze a little theory, a driver from one USB device can be mistakenly used by the system to start another USB device. To eliminate these problems, we need to first remove all existing drivers for USB drives, and then reinstall them.

Such a problem may display the message "USB device not recognized", or unexplained processes occur at the system level that block access to data or cause the system to freeze.

Delete via DriveCleanup

You can effectively remove all existing USB device drivers using the DriveCleanup utility. Its advantage is that it searches the entire system for installed drivers and only then removes them.

First of all, turn off the computer, disconnect all USB devices from it in order to avoid conflict situations while the program is running. We turn on the PC, go to the official website of the program and download the executable file. The utility is compatible with any version of Windows, including different bitness. When downloading, pay attention to the version of the file.

Automatic installation

You have removed all drivers from your computer. For the device to function normally, the operating system must have drivers for it. The automatic driver installation process is incredibly simple, you just need to plug a USB flash drive into the USB port, and then the installation will start immediately. A window will pop up that will display the progress of the installation, on some systems this may occur in a mode invisible to the user. Installation is complete within one to two minutes and you can use your device.

Manual installation

Manual installation means installing drivers not directly from the storage medium itself. We can also install drivers for a flash drive from third-party Internet resources, but in order to avoid conflicts, we will install drivers for a flash drive using another computer.

So, we take our problematic flash drive, insert it into another computer, where it is recognized. A prerequisite for this process is the coincidence of Windows versions on both computers. We use the system searches and find two files.

By any means we transfer them to the problem computer, be it sending by mail or using another removable media. You need to place these files in a folder with the same path that was on the first computer and confirm the replacement when the corresponding window pops up. We reboot the computer and enjoy its performance with FLASH disks.

We have considered only the most common reasons why a USB flash drive is not displayed on a computer. In fact, there are many more of them. Moreover, there are problems that are expressed by other system messages, and their solution is already described in the paragraphs of the article.

The message "Insert disc" appears, even if the flash drive is already connected to the USB port

This system error occurs if the drivers overlap and interfere with the normal functioning of USB devices. In order to fix this error, you need to remove all drivers for USB devices and reinstall them. This process is described step by step in this article.

Disk formatting message

This message appears if you are using a USB flash drive for the first time or a system failure has occurred in it. In addition to the message, you can make sure that it is not usable, because it does not display either free space or occupied space. The solution to this issue is described in detail in paragraphs 8 and 9.

Data error message

This problem pops up in 3 cases. This is a driver conflict, a file system conflict and a failure of the flash drive itself. It is solved by reinstalling the drivers, if it did not help, then quick formatting in order to preserve the ability to recover data on a USB flash drive. See above for step-by-step instructions.

Complete system freeze immediately after connecting the flash drive to the computer

This issue has already been discussed in the article, but I would like to draw your attention to the fact that this error can occur for two reasons:

1. Driver conflict.
2. Bad port.

It is easy to check what problem you have, insert the USB flash drive into another port, if the hang continues, then there is a problem with the drivers. Instructions and tips for reinstalling them were given within the framework of this article.

Why the computer does not see the USB flash drive when the indicator on it is on

The contact on the flash drive, which is responsible for the transfer of information, may be damaged. It is possible that there is a conflict of drivers and the assignment of a busy letter for a partition. If the problem persists, after connecting the flash drive to another computer, try to check the availability of the partition. If everything is in order here, then reinstall the drivers and the flash drive will work.

Error 43 / Error 43

This error immediately stops reading information from a removable device, which means that we will not be able to access the data immediately. There are several problems that Error 43 can cause.

• The failure of the device itself is the first of them. Check on another computer if this situation occurs again.
• Driver Conflict - The solution is described above.
• Updating the hardware configuration - you just need to roll back the driver version in the Task Manager.

conclusions

We got acquainted in detail with the reasons that can interfere with the reading of the flash drive and the information on it by the computer. The described solutions with step-by-step instructions will definitely help you get rid of this problem. The unreadable flash drive can only be a verdict if the flash drive is faulty. In other situations, this is an easily reversible process. If you have any questions or you could not find a solution to your problem in the article - leave comments, we will try to clarify the situation together.

Most of the information today is stored on flash cards. Photos or movies, documents or other information on the microSD card can easily be read through the adapter in the laptop. When problems with the reader appear, the exchange of information becomes impossible, which creates many problems for the user.

Today, of all types of portable memory cards, the microSD flash cards are the most convenient and ubiquitous ones. They are used in phones, smartphones, iPods, tablets, cameras and other portable and computer equipment.

To find out why the laptop does not see the micro SD flash drive through the adapter, you can independently try to find the cause and eliminate it, or use the help of the Orion Service specialists.

Features of reading from microSD card

To read data from microSD, you need an adapter, which is usually included with the purchased flash card. To turn on, the flash drive is placed in the adapter, and the adapter itself is connected to the connector on the laptop (on the side or in front of the laptop panel, the SD connector). If the flash drive has a new format, for example, SDHC, some obsolete laptop models may not recognize and read this type of flash card. The solution to this problem is to buy an external card reader that is turned on via the USB port.

Probable causes of the malfunction and their solutions

The laptop may not see the microSD flash card due to many reasons.

Software error

You can determine the state of the OS and software by testing the laptop with utilities that allow you to see all the errors that have occurred. For accurate diagnosis, it is recommended

hand over the laptop to the service center "Service Orion".

Lack of required driver

In the absence of a driver on a newly purchased laptop, you can install it from the disk that is attached to the product. If the laptop is an old model, bought from hands or has been formatted disks, it will not be difficult to find the right driver for it. To do this, you can use programs to update drivers

Infecting laptop with viruses

There are a number of virus programs that block the device's ability to freely access disks. The solution to the problem is to run the antivirus program, recognize the malware and remove it.

USB flash drive breakage

To make sure that a microSD flash card is broken, you need to install it in another laptop or device. If the problem occurs again, the reason lies in the flash drive itself; if the laptop sees it, you need to look for the reasons in the device itself.

In order to restore the functionality of the external storage medium, you can try to format the disk. The procedure proceeds with the clearing of all information recorded on the carrier. Formatting can be requested by the laptop system itself or be called forcibly using the command in the context menu (if the flash drive is identified by the laptop and is displayed in Explorer).

Card reader does not support microSD reading function

To fix the problem, you can buy an external card reader or order a replacement of the old card reader by hardware repair.

Discs have the same letters

One of the problems that you can fix with your own hands is the coincidence of the letters of the hard drive and the flash drive (for example, the letter F). In such a situation, "My Computer" reflects only one drive, usually built-in rather than external media. To correct this situation, you need to change the drive letter through the Disk Management dialog box (command of the Win and X keyboard shortcuts).

If you urgently need to copy or use information from a microSD card, you can not use a USB flash drive and adapter at all. For example, data reading is possible from a card on the phone without removing it. All you need to do is connect your phone to your laptop using a USB cable. In Windows 7 and 8, there is no need to install special software for this, since the system automatically selects a driver, recognizes a USB flash drive and reads videos, photos, text files and files of other formats.

Sometimes a problem can arise due to a banal loss of contact. This usually happens with frequent removal and insertion of the microSD flash drive into the adapter. Trying to remove and reinsert the memory card may fix the problem.

If all attempts to remedy the situation on their own did not give the desired result, the breakdown can be repaired at Devay Service. Here, specialists carry out full diagnostics, determine the exact reason why the laptop does not see the microSD flash drive through the adapter, and quickly restore this laptop function at affordable prices with a guarantee for the work performed. In this case, the repair time is a matter of hours.

1. Not all MicroSD cards are suitable for every mobile phone. In most cases, their ability to function is dictated by size constraints.
2. Newer models support cards up to 128GB. Older models can often only use cards up to 16GB or 32GB.
3. Check the smartphone manufacturer's website or the operating instructions for which card sizes are supported by your model.

MicroSD card: dirty contacts

1. Contacts both on the microSD card itself and in the mobile phone slot can get dirty. This can also lead to the fact that the card is no longer recognized by the smartphone.
2. Check contacts for dirt. You can clean them with a cotton swab and a little rubbing alcohol. Never use water or other liquids for cleaning.

Connecting MicroSD Card to Mobile Phone

1. Make sure that the MicroSD card is correctly inserted into the card slot, i.e. the smartphone.
2. Push the card again to check if it is fully inserted. In this case, do not press too hard so as not to damage the contacts.
3. Check if the card is inserted correctly into the slot at all. Often there is a small symbol next to a slot that shows exactly how the card should be placed in it.

What if the MicroSD card is brand new or can't be saved anymore?

Brand new cards must be formatted first. Even if the card is not recognized, this procedure is often the last resort. It should be remembered that all data stored on the card will be lost. Here's how to do it:

1. Connect the MicroSD card to your PC. To do this, you need an SD adapter or USB card reader. The map will appear on your computer as a separate disk.
2. Now, to delete all data, you need to download an application called Eraser. With it, deleting data works better and more reliably than with simple formatting.
3. Install the program.
4. Create a task in "Erase Schedule". This is done through the menu by clicking on the right mouse button.
5. Click on "Add Data".
6. Set "Target Type". In the drop-down menu, you can also select your Micro-SD card.
7. After that, a new task will appear in your "schedule". Run it by clicking on the right mouse button.
8. You can then assume that you have securely deleted all data from the card.

SD cards are a type of storage device used in phones, cameras and camcorders. In some cases, a problem arises when the computer or card reader does not see the memory card of the camera or phone. The user inserts it into the appropriate port, but it does not appear in the explorer.

We check if the card is supported by the card reader

Users often confuse different types of drives, at the moment there are only three: "microSD", "miniSD" and "SD". At the same time, a certain format is required for each device. the requirements for the speed of work, the amount of memory are different.

Briefly about the types and characteristics of memory cards:

Working with a card reader, checking compatibility:

• microSD with card readers can be used as an SD card. But it is not always recommended to do this (due to different data exchange rates);
• SD card readers are backward compatible: i.e. if you take a device that reads SDHC, then it will read SD cards of 1 and 1.1 generations, but will not be able to read SDXC. Pay attention to which drives are compatible with the adapter.

We check the flash card and card reader for serviceability

To check the flash drive for serviceability, just install it on another device. If there is another card of the same model, check if it is recognized on the computer. There are several reasons that affect the operation of the memory card: improper removal of the device, physical wear, or damage. In the first two cases, you can try to restore the performance of the media using special low-level formatting utilities.

We use the SDFormatter program to recover a flash drive in SD, SDHC and SDXC formats:

If the problem lies in the card reader itself, then in this case you will need to contact the service center. If you need to immediately use the drive, purchase a special USB adapter equipped with a card reader, it can be connected to a laptop.

The problem can also occur due to incompatibility, at the moment there are several types of flash drives: SD with byte addressing and SDHC with sector-by-sector. To rule out incompatibility, it is better to use USB adapter SD-MMC... With it, you can use several types of memory cards.

Operating system errors

In some cases, a computer or laptop does not see the SD card due to errors in the operating system, we will give a list of common failures:

Viruses on the computer

The reason why the SD card is not detected may be the presence of viruses that can interfere with the operation of USB ports. Install an anti-virus program such as "Kaspersky Antivirus" or "Dr.Web Cureit" and scan the system. If any malicious files are found, it is recommended to delete them.

Important! To prevent files from being deleted from the flash drive, make a backup.

Checking the drivers

When MicroSD is not detected, you can use programs to identify outdated drivers and update them to the latest version. DriverPack Solution is a utility that allows you to check your system configuration and update drivers. Download the utility, install it on your PC and run. After starting the program analyze the system and check if the drivers are up to date. Select the tab " Configure components automatically”And wait until the installation of the required files is complete.

We check if the card is identified on the computer

We check if the system was able to detect the drive:

• open the explorer through the shortcut " My computer"On the desktop;
• select the menu " This computer"And open the section" Devices and disks»;
• if a new disk appeared, the flash drive was detected.

Second way:

Computer hardware problems

If it does not open or is not detected when Micro SD is connected via an adapter to a computer, it is worth checking the card reader for operability. First of all try insert into adapter a knowingly working USB flash drive, if it is not detected, then reinstall the drivers on the card reader.

Checking the drivers:

File system conflict

In some cases, the flash drive can be detected, but it cannot be opened. The reason is a conflict of file systems or a damaged file system on the media itself. If the data stored on the flash drive is not important, you can format the card to the NTFS file system:

Already used section letter assigned

This situation occurs when an SD card is connected to a computer, when the system assigns it a letter to an existing drive. Because of this, a crash occurs and the flash drive is not displayed in the explorer.
