The computer does not see the flash drive, how to fix it. We find out the reasons why the computer does not see the flash drive

OS Windows family, produced by Microsoft, often do not see USB devices, and there can be a lot of reasons for this.
How this manifests itself and whether there is a way out of the situation is the topic of our article. We will dwell on the reasons in more detail and try to consider each case separately. If your laptop or Personal Computer does not see the USB flash drive, this manifests itself as follows:

  • You connected a USB flash drive, but the computer displays the message “insert USB device.”
  • The flash drive is connected, as evidenced by the icon and sound, but file manager she's not there.
  • A warning appears about formatting the USB device.
  • A data error warning appears.
Before you try various ways to eliminate the problem of the invisibility of the flash drive, make sure that the drive is not physically damaged, and also use one of special applications, which diagnoses and fixes errors in USB devices. For example, special utilities developed by Kingston and Sandisk corporations.

Check if the computer sees the connected flash drive in Disk Management

To start it special utility control USB devices, do the following:

Open the Disk Management tab and turn the flash drive on and off several times. If a connected USB device appears, the computer will notify you that each of its sections (there is only one in the flash drive) is working. In this situation, the easiest way to fix the error is that the PC does not see the flash drive. Right-click on a section to make that section active. You can also assign the letter E or D to the flash drive. After this, you will see that the computer has recognized the USB device.

And if, after reconnecting the device, the partition status is displayed in “Disk Management” as “Not allocated,” then it either does not exist, or it is working with errors. Right click and create a partition. But this can only be used if there is a “Creations” item in the menu simple volume" If you create a partition, the flash drive will be formatted, although all data stored on it will be lost.

If in the utility you find a label “uninitialized” USB device, it means it is damaged. You can try to restore the drive's memory. We will tell you how to do this later. If you have previously created partitions on a USB device that are not supported by the Microsoft operating system, then you need to delete them. Step-by-step instructions will tell you how to do this.

Further simple steps

Using the OS device manager, you can view all installed USB devices and check that they are working correctly. See how your USB flash drive is displayed in the manager. The flash drive connected to the computer may be unknown, identified by its own name, or labeled as a USB storage device.


This flash drive must be removed. Then "update USB storage configuration".


Very often, after these steps, the updated USB device is displayed in the OS file manager.

There are also other situations that lead to an error in which the computer does not see the flash drive. Perhaps you are connecting a USB device using an extension cord or USB hub? Then try directly connecting the device to each of the USB ports in turn. Perhaps one of the ports is inoperative and you don't know about it.

Try another option. Turn off your computer and remove everything that was connected to it (printers, cameras, external media, card readers and other devices connected with via USB), leaving only the necessary minimum and storage. After this, turn on the computer. If the PC saw the connected storage device, you have found the problem. The problem is that there is little power supplied to the computer's USB ports. In this case, replacing the power supply or purchasing a USB hub will help you.

Windows 10 does not see the flash drive after updating or installation (suitable for Windows 7, 8)

If you have updated your operating system, there is a high probability that you will encounter such a problem. In this case, the problem lies either in the lack of a recent version of USB drivers, or in the fact that the registry entries for USB devices are outdated.

If this is the second option, you can use the USBOblivion program. You can download it for free to the author and remove all outdated entries. Be careful! Before deleting, it is better to create a restore point so that if USBOblivion does not work correctly, you can undo the erroneous actions and return to the previous settings.


Before starting the utility, disconnect all flash drives connected to the USB ports. Only after that, run it and clean the registry, after saving old entries to a file.


After cleaning the registry, reboot and reconnect the drive. If the computer again does not see it, follow step by step all the steps we wrote about above: remove it, update the configuration and connect again.

If you have an operating system version 10, then an error may occur due to driver incompatibility. If this is the case, there will be a mark next to the driver - an exclamation point. In this case, download updated versions on the official developer pages. Do not use third-party sites to search for drivers, especially if you need to update them for your mobile computer. In some cases, it is recommended to update and " basic system input/output (BIOS).

If the flash drive is not seen by Windows XP

Owners of Windows XP, especially SP2 builds, often encounter a problem in which the computer does not see the flash drive. This problem is due to the lack of updates in the operating system that would allow working with USB devices.

If you have this operating system and encounter the problem, follow these steps:

  1. Update the build to SP3 and remove the IE browser.
  2. Update your operating system, even if you have a new build.
  3. If the problem occurs on Win Vista, also update the software first.
The new build of Windows XP came with updates that allowed USB drives to work correctly. The following errors in the new Windows versions XP have been patched by Microsoft:
  • KB967132 - in previous version It was impossible to connect multiple flash drives or other devices. When interacting with each other, they caused crashes, freezes and critical system reboots.
  • KB898962 - when the printer is turned off, the flash drive also stops working correctly.
  • KB315634 - it is impossible to connect new USB flash drives, although old ones that were previously used work without problems.
  • KB924196 - this error indicated that personal/ mobile computer I did not see the connected flash drive or portable media player.
  • KB88840 - when connecting/disconnecting a USB device, a computer or laptop displays a warning about a common Rundll32.exe error.
  • KB362370 - the new build of Windows XP now supports the second version of the USB port.
  • KB881233 - after the computer wakes from sleep mode, the flash drive does not appear in Device Manager. A problem similar to the previous case occurs after the computer comes out of hibernation.
  • KB857900 - after turning flash devices on/off again, the port did not work correctly.

Completely remove old USB drivers

You connect a flash drive, but the computer does not see it and displays a warning about its absence. The problem may be that your old drivers do not work correctly and, therefore, the USB device cannot be assigned a letter. Old drivers can also cause problems with rebooting, freezing, or incorrect operation of the computer when a flash device is connected.

Drivers operating system Microsoft is installed by default, immediately after the first connection external storage. Then this one installed driver it remains in the OS. But when connecting another device, the driver may not work, causing crashes and other problems. In a word, to solve all kinds of problems associated with incorrect work drivers, they must be removed and new ones installed again.

How to remove drivers for all USB devices

Step one After turning off the computer, remove everything: printers, cameras, external media, card readers and other devices connected via USB.

Step two Boot the operating system.

Step three Download from official page author free program DriveCleanup, compatible with all versions of Windows.

Step four The drivecleanup.exe file must be copied to

C:\Windows\System32\
Step Five In the command line, write drivecleanup.exe.

Step six The program will clear all drivers and entries.


After the computer restarts, insert the flash drive and wait while the utility installs the updated drivers.

Reinstalling USB devices in Windows Device Manager

If you have used all the methods discussed and none of them helped, follow these four steps:
  1. In Device Manager, enter devmgmt.msc.
  2. From Device Manager, open the USB Controllers tab.
  3. Delete everything where the names include USB hub, Hub, Host Controller.
  4. Update the USB device configuration from the manager.
After completing all four steps, reconnect the flash drive. Perhaps the problem will be solved, and your personal or mobile computer can already see all external devices.

Additional actions

It would also be a good idea to perform the following four steps in sequence:
  1. A possible reason that a computer or laptop does not see flash media is the presence of viruses. Download if you do not have it installed, and check all disks.
  2. A possible cause could also be an incorrect registry entry. HKEY_CURRENT_USER\ Software\ Microsoft\Windows\ CurrentVersion\ Policies\ Explorer. NoDrives must be removed, and then restart your PC or laptop.
  3. In registry entries HKEY_LOCAL_MACHINE\ System\ CurrentControlSet\ Control you also need to remove StorageDevicePolicies.
  4. If all else fails, completely unplug your computer. Unplug the cord from the outlet, having first disconnected the PC or the battery from the laptop, and hold the power button for a while. After this, you can turn on the computer and try the flash drive.

Recovering data from a flash drive that the computer cannot see

If the computer sees your flash drive, but it is listed as “uninitialized” with an “unallocated” partition, then the device’s memory is damaged. Do not despair prematurely: in some cases, all information stored on a removable drive can be restored.

When using flash drives, remember two simple things that, in case of unexpected situations, will help you restore everything that was stored on them:

First, if you want to restore a flash drive, do not copy additional information to it.

Second, if you are restoring the device’s memory, save the information from it to another flash drive.

We recommend that you use the best utility- . The program is free, effective, and has a Russian language clear interface and two versions - installation and portable - therefore it is very popular among different categories of users. Using this software, you can recover absolutely all information from all media, not just flash devices.

The utility works both manually and automatic mode, and even beginners who have never dealt with such software. Recuva itself will offer The best way to restore all information from a damaged flash drive, you just have to agree by clicking the confirm button.

If after all the manipulations you still cannot connect the USB device to your computer or laptop, the recovery program cannot be used, and the information stored in its memory is very important, we recommend professional help specialists dealing with these problems. They will restore both files and all content stored on the damaged device.

External hard disks and USB flash drives are generally easy to use - you connect them to the appropriate connector, and you can immediately work, write and rewrite information. Their convenience and indispensability are difficult to overestimate. But in some cases, when you connect a removable drive to a USB port, you find that the computer does not see the flash drive, and the drive indicator does not light up.

The problem may be caused by partition errors (for example, the wrong file system is being used), non-working USB ports, driver problems in Windows, or other problems. In the worst case, the flash drive itself may simply be damaged during use or as a result of mechanical damage, but, however, the new flash drive may not work when connected.

Let's take a closer look at why the computer doesn't see the flash drive and what to do to fix the problem yourself.

Let's make a reservation right away - sometimes a malfunction due to which the flash drive does not work on a computer or other device may be in the BIOS. For example, in the BIOS settings it is disabled USB support devices - that's why the computer doesn't see the flash drive.

But it happens that the BIOS itself cannot detect a removable device. For example, you created bootable USB flash drive, but it is not recognized when the computer boots.

Why might this happen? If in the settings the boot priority is set to a removable device, most likely the created bootable flash media was simply written incorrectly. You should recreate the bootable USB flash drive using programs that can be easily found on the Internet and then try to use it again and check if it works on another computer.

The indicator is on, but the flash drive is not recognized

In this case, most likely there is still a chance to restore it, but maybe the problem is not there. This means that the situation is not fatal. Because, in fact, the indicator light just means that there is no power supply. That is, the device may turn out to be quite working.

What could be the reason?

USB port The sockets on the front panel are not connected - this is perhaps one of the most common reasons. Often, users connect a flash drive to the front USB port and find that the indicator does not blink - it happens that the cable was not connected to these ports when assembling the computer.

There are two solutions here, and both of them are quite obvious and understandable. First, connect the removable drive to the rear USB port, if everything works, the problem is in the front ports. The second option is to check and if there is no connection, connect the cable from the front ports to motherboard computer.

Other most common reasons why a flash device is faulty

First, let's check if Windows detects the drive when you connect it to your computer. If you are using a portable hard drive, connect it to your computer via USB cable. Some removable drives may have separate power cables that need to be connected before everything starts working.

To check whether the external HDD or flash drive, open the management tool. To do this, press Win + R, enter the combination diskmgmt.msc in the dialog box.

You should see connected external drive among those listed in the Disk Management window. Even if it doesn't appear in Explorer because it doesn't contain any partitions (not formatted), it should appear here.

If you see the drive in this menu, it means that Windows has detected it, after which you can format it and the device will be ready to use. If you do not see the removable device in the control window, proceed to the next section, in which we will try to determine why the computer does not see the flash drive.

Special connection options

Some users prefer to connect a flash drive via a USB hub or extension cable. This, of course, is sometimes more convenient, but in this case the malfunction also occurs in the adapters. Try making a direct connection.
And it happens that a lot of devices are connected to the computer via USB (for example, through the same hub, which itself is quite functional), and there is simply not enough power for the flash drives. This, however, happens quite rarely in modern cars, but still remains quite possible. Try disconnecting other devices, and if everything works, that was the problem. In this case, the solution may be to install more powerful block power supply or simply not using too many devices at the same time.

USB port problems

If Windows does not see your removable drive in any modes and after formatting, too, there may be a hardware problem with the USB port, a driver problem, or simply the connected device is faulty. What to do in such cases?

First, unplug the drive from the USB port and try connecting it to a different USB port. If it works in one but doesn't activate in the other, your USB connector may be bad. If you connected the drive to a USB hub, try connecting it directly to your computer. Some USB hubs do not provide enough power for your external drive.

If the drive doesn't show up in the management program even after you unplug the USB hub and plug it into another port on your computer, it's hard to know for sure whether the removable media is bad or the computer's motherboard has problems.

If you have another computer nearby, try plugging a USB device directly into it to see if the hardware is detected. If the media does not work on any computer when connected, do not forget to check whether it appears in the disk management window - if not, most likely the device itself is damaged, and you will need to replace it (buy a new one) or repair it.

If the drive works on other computers or you don't have another computer nearby, check this on your own. Windows system There may be a driver problem with the connected drives. You can check this using Device Manager.

To open it, press Win + R, enter the combination “devmgmt.msc” in the dialog box and press Enter.
And sometimes it also happens that there is a virus in the system that has infected a file USB storage device. In this case, the device either does not boot at all, or the antivirus simply blocks it.

Sometimes the flash drive is still recognized, but when accessed, an access denied error appears. In this case, it is usually worth destroying the autorun.inf file via command line- first Start, then Run, then “cd F:/” (or whichever drive letter is used for the flash drive), then the command “attrib -a -s -h -r autorun.inf”; "Enter"; command "del autorun.inf"; "Enter". In this case, it is better not to turn off the antivirus to avoid infecting the system.

Drivers

Look in the manager connected to this moment devices to check for equipment with a yellow exclamation mark next to them. If the flash drive's indicator is not lit and you see a yellow exclamation mark, there is no doubt - this indicates problems with the drivers.

Right-click on the device with the yellow exclamation point, select the Properties option, and look at the error message. This bug report may help you resolve the issue, but you can do a Google search to find out the actual problem in your specific case. Be sure to enter the code if it is present or retype the error exactly to get the most reliable information that will help solve your driver problem.

System Restore

Problems with a flash drive can sometimes be quite difficult to fix. If the problem occurred recently, you can take extreme measures - run a system restore. You can use the Update Driver button to install an updated, working driver and roll back any changes, or use the Remove feature to remove the device from your system and hope that Windows will automatically reinstall the driver and then set it up correctly when you reinstall it. USB connection drive.

Today, you practically cannot find a person who does not have a flash drive in his arsenal. This device is a universal thing and is used everywhere. On TVs, music centers, in cars and other devices. The more often we use a flash drive, the faster it deteriorates and the computer stops finding it. In this article I want to tell you several ways to fix the problem of an “unreadable” flash drive.

Case one

Insert the flash drive into the USB port on the back. If it doesn’t help, then unfortunately your flash drive is dead.

Case four

You insert the flash drive into the USB port, and it asks you to format it. I'm afraid that in this case you will have to format it, or else it won't work. This could happen if the flash drive was not removed correctly or it was removed during copying, preventing the process from being completed.

Case five

USB device not recognized. There is no need to panic in this case; the cause may be dust or dirt that has stuck to the contact ports. Try inserting the flash drive into another port - it doesn’t read? There are two options: either reinstall Windows or the driver, but it’s better to try the second option - you shouldn’t reinstall Windows right away.

Well, that's all, I have listed the most basic problems that occur when the computer does not see the flash drive.

Hello!

A flash drive is currently one of the most popular types of storage media (except for the ability to share files over the network).

In fact, a USB flash drive has a lot of advantages: it is mobile (can be put in any pocket), universal (connects to any PC, laptop, gadget), copying/reading information from it is quite fast, etc.

But one small thing happens to them" problem“- sometimes the computer refuses to recognize and see it. There are quite a few reasons for the invisibility of a flash drive, in this article I want to give the most basic ones that I most often encounter in my work.

Also from the article you will learn what can be done to restore the functionality of your device (you shouldn’t always immediately throw it away and run to buy a new one?! 👣).

If you want to buy flash drives at bargain prices, I recommend using Chinese online stores:

Reasons for the invisibility of a flash drive

10 Main reasons and their solutions...

Problem #1: the flash drive is not formatted

This reason is the most common! The fact is that after purchasing a flash drive, you need to format it (very often new flash drives and disks are not formatted at all and therefore they are not visible in “My Computer/This Computer”...).

Solution

It is most likely pointless to go into “My Computer”, because... in some cases you won’t see a flash drive there.

Therefore you need to open "Disk Management" . To do this, press the button combination Win+R (The Run window should appear) , enter the command diskmgmt.msc and press Enter (screenshot below).

Remark! If your flash drive is not visible in Disk Management, go to the 3rd problem.

Find your flash drive in the list (guide by its size and name, for example, "Kingston...8 GB") , then click on it right mouse button and in the appeared context menu choose - " Format... " (example in the screenshot below) .

Actually, that's all. By the way, file system I recommend choosing NTFS (because on FAT 32, which is often the default on flash drives, it is impossible to copy and place files larger than 4 GB).

Problem #2: incorrect auto-installation of drive/flash drive letter

When you connect any disk drive, flash drive, floppy disk, etc. to your computer - it automatically assigns a unique drive letter to your drive, e.g. "System disk C:\" or " Local disk F:\", etc.

Everything would be fine, but sometimes the auto-installation of the letter fails and assigns a non-unique letter to your connected drive. As a result, the drive is not visible...

To solve this, you just need to try changing the letter (this is done quickly and very often solves the lion's share of problems).

Solution

You also need to go to "Disk Management" (how this is done is described above), then select your “invisible” drive, click on it right mouse button and select the function " Change drive letter or drive path ".

To help!

By the way, in some Windows cases may not assign a drive letter to all connected drives at all. To fix this, use the following recommendations:

Problem #3: Outdated or broken drivers

A very, very common problem is outdated drivers (also sometimes drivers can fail and conflict with each other). It is worth noting that on older computers another problem is possible - the inability to see a flash drive whose size is more than 32 GB.

This can be solved in the following way: first remove the old drivers, then install new ones.

Solution

First of all, open the device manager, where you can see all the devices connected to the computer. To do this, open, then switch the view to "Large icons" and select "from the list" device Manager " (example in the screenshot below).

To help! Alternative ways to open Device Manager -

Note!

Devices that do not have drivers will display a yellow exclamation mark. In general, it is not advisable for you to have such devices marked exclamation marks(or red crosses).

After uninstalling, click the "" button - it is located at the top of the Device Manager window. After which, your manager window will blink a couple of times, and the drivers will be reinstalled...

Problem #4: the front panel of the system unit is not connected

Very often, the USB ports on the front panel of the system unit are not connected to the motherboard (apparently, they forget to connect this socket when assembling the PC). In this case, you simply insert the flash drive into a port to nowhere...

Solution

  1. Quite simple: connect the flash drive to the back of the system unit - it always has 2÷4 USB ports. At the very least, it is recommended to do this simply for testing - to confirm that the USB ports on the front panel are not working.
  2. Try connecting the front panel to the mat. board If you have never had such experience before, go into system unit I don’t recommend it, it’s better to use the services of service centers.

Problem #5: viruses on a PC or flash drive

Settings for enabling USB ports are usually located in the "Advanced" tab. On opposite point USB Controller need to convert the value to Enabled(i.e. enabled, see screenshot below). Then save the settings and exit (usually F10 key).

You can also just reset BIOS settings to optimal (USB ports are always included in them. At least I have not yet seen the opposite...).

Problem #8: File system error

In cases of file system failure - when you connect a flash drive, you will most likely see a message that the flash drive is not formatted, that it has a RAW file system and Windows will prompt you to do something with it 😊.

In some cases, formatting a flash drive cannot be completed due to some errors...

In general, the problem with the file system is quite “big”, and its solution is not always simple and quick (especially if the flash drive has the necessary data).

Solution

If the data on the flash drive is needed- I don’t recommend formatting it. In general, I advise you not to do anything with it, but take it to a service center. If you want to do everything yourself, then first try to remove your data from it using recovery utilities: Recuva, R.Saver, Easy Recovery Professional, etc.

If the data on the flash drive is not needed (or you have already copied it): I recommend trying to format the flash drive using one special. utilities - HDD LLF Low Level Format Tool.

HDD LLF Low Level Format Tool

A simple utility for low level formatting disks and flash drives. In a number of cases, it helps to bring drives back to life, for which there was practically no hope left. By the way, it formats even those disks that Windows does not see or gives reading/formatting errors.

The utility works quite simply: after launching, it will present you with a list of all connected drives to the system, you select the one you need and format it. After formatting, the disk (or flash drive) starts working as it should!

Problem #9: USB port malfunction

It also happens that the USB port becomes unusable. Most often this happens due to frequent and careless use of it: for example, many people sharply pull the flash drive (or USB cable), over time the USB port begins to fit poorly to the inserted flash drive (i.e. there is no contact between the flash drive and the port). As a result, the flash drive is invisible.

Note. By the way, the USB port may not work stably: i.e. you will first see the flash drive, and after you start copying information onto it (or reading it) - you may see an error, or the connection will simply disappear...

Solution

  1. Try connecting the flash drive to another USB port, or to another computer/laptop. If the problem is related to the USB port, you will immediately notice the difference...
  2. I also recommend paying attention to dirt in the USB port. Often, over time, a layer of dust, plaque, etc. accumulates, which leads to poor contact. If there is a lot of dirt, try removing it with an old toothbrush dipped in alcohol. (perform the operation with the PC turned off!) , and then reinsert the flash drive.

Problem #10: USB flash drive malfunction (for example, after being dropped)

This is perhaps the worst thing that could happen to the drive, especially if it contains important data. Most often, the user guesses that the flash drive may have become unusable, because... before that:

  • the drive fell to the floor;
  • was dropped into water;
  • accidentally touched or hit by any object;
  • The drive shows deep scratches, chips or cracks.

In general, when you insert a flash drive into a USB port, the LED on it should light up (most flash drives have one). The characteristic sound of connecting the device should “ring” on the PC. If all this is missing, especially when connecting a flash drive to different devices– then this is a bad sign, most likely there is a problem with the flash drive itself.

Solution

  1. Buy a new flash drive (banal and simple 😉, especially since the prices for them are now quite affordable (and they generally cost “pennies”));
  2. Try taking it to a service center, maybe the technician will be able to resolder the contacts and it will work again (but I would recommend this method only for). After repairing the drive: using it for important data is not justified!

Every person has encountered a very unpleasant situation when the PC does not see the flash drive. The reasons for this phenomenon can be very different, but in the most common cases, eliminating this problem does not require special knowledge or skills; it is enough to just have a basic understanding of the operation of the device.

If you know nothing at all about the desktop, but... standard methods solutions to this issue do not help, then this article will help you. It will discuss the main reasons why the PC does not see the connected device and methods to solve this problem.

Device failure

The most commonplace, but at the same time the most unpleasant option is a drive failure. To check this, you need to try using the flash drive on another computer. If he also does not see the device, then the diagnosis is obvious. Unfortunately, in this case nothing can be done. Your only option is to buy a new drive.

USB port problem

There are often cases in which the drive is not visible to the computer due to problems with the USB port. If we are talking about the rear port, then most likely the problem lies in its breakdown. In this case, it is recommended to call a technician who can repair it. But if the drive was inserted into the front USB port, then brighter scenarios are possible.

  1. One option is low front port power. In this case, it is recommended to simply insert the drive into the rear port.
  2. The front USB port may not be connected to the motherboard. In this case, you just need to connect it to system board. But if you do not understand computers at all and cannot do this, then you should call a specialist. If you don’t want to use the services of a specialist, you can simply insert the drive into the rear USB port.
  3. If the previous tips did not help, then you should look into the BIOS. The fact is that sometimes the manufacturer disables USB ports. This happens quite rarely, but you should still not forget about this possibility. In this case, you need to go into the BIOS (if Windows startup press Del, F2 or another key, which depends on the PC manufacturer). You need to find it in bios Configuration section USB-> Advanced-> USB configuration and enable USB ports there (USB Controller must be).
  4. As with the rear port, the most common failure is also possible. Again, it’s worth calling a professional.

Virus on computer/flash drive

The likely reason why Windows does not detect the flash drive may be a virus. Therefore, if your desktop suddenly stops seeing the connected device, then it is worth checking both the computer and the drive for a virus. If after scanning a virus is found, the antivirus will fix the problem and your PC will safely see the device.

Driver failure

The PC may not detect the USB drive due to a driver malfunction specific device. In order to check this, you should go to the device manager (My Computer-> *Right Click*-> Properties-> Hardware-> Device Manager). Next, you need to click on the black plus, which is located next to the “USB Controllers” section.

Then you need to insert the drive and pay attention to which driver has changed. It needs to be removed. Immediately after this, we take out the flash drive and immediately insert it back. If you deleted that driver, the installation of a new driver will begin. After this, the PC will be able to see the connected device without any problems.

File system incompatibility

To solve this type of problem, you need to format the drive for the required file system. If you need to find out the file system on your PC, then you should go to My Computer-> *Right-click*-> Properties. In this section, you will learn which file system you need to format the drive into. This can be done using special program, which will see the flash drive if your problem really is incompatible file systems. In the program settings, specify the required file system and after a couple of minutes you enjoy the fact that the desktop sees your device.

Problem with recognized drive partitions

If your USB drive is detected, but it is not in the device partitions, this means that it has been assigned the letter of an existing partition. This problem occurs quite often, but it is very easy to solve. To solve this, you need to go to Control Panel->Administration->Computer Management->Disk Management. The central part of the screen will contain all the drives that are currently connected to the system. You must click on " removable drive"(this is how your Flash card will be recognized) and then select the "replace drive letter" option. Here you change the assigned letter to any other free one, after which it will definitely be visible to the PC.

USB port is dirty

Perhaps this is one of the most common reasons why a PC does not see a flash drive. If the connector is dirty, you just need to clean it. As a result, your drive will become visible to the computer (of course, if there are no other problems).
This article examined all the possible reasons why a computer may not see a flash drive. If suddenly you could not solve your problem, then you should double-check each of the possible reasons. And then your flash drive will definitely be recognized by the computer.
