Doesn't see the flash drive but the connection sound. What to do if the computer does not see the flash drive. The computer does not see the flash drive due to a non-working USB port

If your computer or laptop, which perfectly recognized the flash drive, suddenly stopped recognizing it, “doesn’t see it point blank” or began to recognize it as an “unknown device” - this is not yet a reason to take your computer or laptop to a service center.

Let's try to solve this error ourselves.

First of all, try inserting the flash drive into another USB port. Perhaps your USB port is the one you always use stopped working for various reasons. If you work on a Personal Computer, problems most often occur when connecting to the USB port on the front panel of the computer. Therefore, to check, use only the port on the rear panel, which are built into Motherboard.

Another reason why the Computer or Laptop does not see the flash drive may lie in a system failure of the USB drivers.

To understand the driver, you can do the following:

Open the device manager; to do this, place the cursor on My Computer and press the right mouse button.

Click on Properties.

In the appeared Device Manager find USB Controllers Red arrow and click on check mark Black arrow.

Remove all USB devices (in Device Manager and reboot, all devices will be automatically detected and installed).

If this does not help, you need to reinstall the driver for the chipset. Thus, drivers for absolutely all controllers are regulated. This can also be done through Driver Pack Download. You can see how to use this program

Another common reason is – viruses. If you connected a flash drive to someone else’s computer (Internet cafe, institute, etc.), that is, in places where you can catch a virus, open the flash drive at home using Windows Explorer . Having discovered on it unknown files– delete .

In order to see all files on your flash drive (There are files that are not visible because the Windows system does not show it by default hidden files). Therefore, you need to do the following.

In the Folder Options window that appears, click the View tab. IN additional parameters go down and click Show hidden files, folders and others…..Click OK.

Hidden files will appear on the flash drive. If the file appears autorun.inf or another file with the same extension *.inf or *.bat, Recycle (trash), feel free to delete these files via context menu(right click on the file -> Delete ).

Another reason why the flash drive is not visible - Perhaps the settings have gone wrongBIOS, rarely, but it happens.

Go to Settings BIOS and check the parameter:

USB Legacy Support. The value should be Enabled…….How to login BIOS look .

If B Task Manager -> Universal Serial Controllers USB bus – the flash drive is recognized as Unknown device . On the menu My computer and in Taskbars…

It’s not there, most likely the flash drive can be thrown away, the built-in electronics are burned out. The data is saved on it, the memory there is non-volatile, and if they are really needed, then specialists will be able to restore them using special programs , but it is expensive and you have to weigh the value of the lost information and the cost of recovery. Although you can do this yourself, which I will definitely write an article about .

Also keep in mind The service life of flash drives is not that long like hard drives and with daily use, average term service for about a year. To reduce the cost of producing flash drives (have you noticed how prices for them have dropped sharply several times), developers are using various tricks, including making memory cells thinner - this reduces the number of write-rewrite cycles by 2-3 times, manufacturers they promise 5000-7000 times, but even this number can be reduced. The number of connections to the computer is also finite, usually 1000-2000 connections.

There are also such situations: when you try to write some information to a flash drive, you receive a message USB device not formatted, format it?.

This indicates that your flash drive has begun to “die” and storing important data on it is dangerous. Formatting in most cases helps to revive it and write files to it, but the next time you try to write, it (the flash drive) may again display such a message. This way you can format it before each attempt to transfer files.

If you receive this or a similar message, then it’s better to download a recovery utility, they are different for each brand of flash drive (Kingston, Transcend, A-Data) . Look for them on manufacturer's official website.

If the newly purchased flash drive is not immediately identified, then there are two options:

• Old drivers;
• Burnt out when first connected (This happens too).

In the first case, go to the website of the manufacturer of your motherboard, download new driver and install.

In the second - go back to the store, exchanged under warranty.

Hello friends! in this article you will find out why the computer does not see the flash drive and what to do in such a situation. Today I will tell you how to deal with a common problem when the computer stops seeing the flash drive and does not display the contents.

We will also consider the option when the laptop does not see the flash drive after formatting. Let's go? I ask everyone in advance to like the article in order to help me develop this blog. Thank you!

The computer does not see the flash drive - what to do?

We have already talked about. But what can you do if the computer does not see the flash drive? We have tried to collect solutions that are really useful and will help resolve this issue for you. If you have any problems additional questions- be sure to talk about them in the comments.

Reasons for flash drive failure

First, let's look at the causes of the described problem, because, as you know, there is no smoke without fire. In our case, there may be many of these reasons, so it is worth paying attention only to the most important ones.

Often, the front panel is turned off on a personal computer, considering it unnecessary. And as a result, we get a number of non-working USB ports.

Not working flash drive. Everything in our world tends to break. For example, flash drives often simply burn out due to improper use or long service life.

It's the 21st century, century high technology, without viruses there is simply nowhere. Transferring infected files from another PC can be fraught with the following things: in the first case, the flash drive itself will not be visible to the computer, and in the second, you will not see the files on the drive. Of course, your machine could also be an infected device, so I advise you to check everything for viruses.

Driver malfunction. This doesn't happen often, but it does happen.

File system conflict. It may be that the drive (flash drive) has a file system installed that is different from the computer, so they may conflict, and the flash drive is not visible on the computer.

Faulty USB port.

The computer does not see the flash drive? Solution!

The reasons why the computer does not see the USB flash drive have become more or less clear, but now let’s figure out how to solve our problem so that the computer finally starts seeing the flash drive.

Let's start with the non-working front panel. In this case, you need to know exactly where the cord is connected to motherboard, otherwise even bigger problems cannot be avoided.

I would advise you to contact service center, where competent specialists would quickly and effectively solve the problem.

Non-working flash drive. A burnt-out flash drive will have to be replaced with a new one.

Malicious programs or utilities. As you may have guessed, the solution to this problem is to scan all disks on your PC with an antivirus program.

Driver malfunction. This problem is not solved as easily as the previous ones, but if you approach its solution headlong, then everything will turn out to be much simpler.

What do we need?

Update driver USB port through device manager. You know how to find the latter from my previous articles.

When you insert a flash drive into one of them, you may notice a slight flicker in one of the list lines. This is what we need to delete by clicking on the appropriate button.

After removing the driver, you will need to install a new one. To do this, insert the flash drive into the same port to which you performed the previous manipulations. That's all, all USB port software is updated.

Point by point, we approached the problem associated with file system conflicts. It can be solved very simply. Format the flash drive, changing the type file system to a similar one installed on your computer. File system name Can find out as follows: My computer - Disk C (right-click on the icon). The properties that appear will show all the necessary information.

The last problem is the easiest to solve. If one of the ports is faulty, then try inserting the flash drive into another; if the others are faulty, there is only one way out - send the PC for repair.

So, I described the solution to our problem for a desktop PC, but users with laptops were unhappy. Don’t worry, because in your situation everything is a little simpler, since there are correspondingly fewer reasons and problems. And they are exactly like this:

• The flash drive is broken
• Malicious code
• Drivers are not working properly
• File system conflict
• Non-working USB port

Conclusions

You already know well how to deal with them, so go ahead! That's all I have for today! I hope now you know why the computer does not see the flash drive and what to do about this problem. If you found the article useful, like it. Also, don’t forget to ask your questions and suggestions in the comments. Peace and goodness to everyone!

Do you insert a flash drive into your computer's USB port, but it can't recognize it? The situation is probably familiar to everyone, and, in fact, quite unpleasant. There are several options for solving this problem, and we will tell you about all of them.

Is the USB port faulty?

It is possible that it is not the drive that is faulty, but the USB port itself. You can check this by connecting the flash drive to another port on your computer or laptop. It is unlikely that several ports on your PC will be faulty at once.

Before you give up on the flash drive, you need to figure out whether the USB port is working

Another way to check ports is connecting another USB device. Connect any such gadget (it could be another flash drive, smartphone, camera, etc.) and check if it works. If yes, then USB port is not damaged. This will also ensure that the USB port driver is working correctly.

Is the flash drive recognized but not displayed?

If the USB ports are fine, but the drive is still not recognized, you can check is the letter of the flash drive name being used by another device?. To do this, follow these steps:

• Right click on "Computer" and select the menu item "Control".
• A window will open "Computer Management". From the menu on the left, select "Disk Management". If the USB drive is listed here, the computer will recognize it, but simply will not display it on the desktop.
• To access the data you need to change drive name (letter), since it's probably already in use. Right-click on the USB device name and select sub-item "Change drive letter or path".
• In the window that opens, click the button "Change", after which in a new window on the right you can assign a new letter.
• Confirm your selection by pressing the button "OK". The computer should now see the flash drive.

If after performing all the described steps you still do not get any results, then most likely the flash drive is faulty. Soon we will tell you how to save data recorded on such a USB drive.

You connect the flash drive to the laptop, but nothing happens - the drive is not displayed in the system, and it is impossible to work with the data stored on it. A very unpleasant situation that requires immediate resolution.

Identifying the cause

The first step is to understand what is not working: the laptop’s USB port or the flash drive. You can use another flash drive to check - if the laptop detects it, then the problem lies in the drive. If the laptop does not find any media, then you will have to check several system parameters, the failure of which could lead to such an unpleasant result.

Checking media through Disk Management

Let's check whether the laptop detects the USB flash drive connected to it using the Disk Management system utility:

1. Using the Win+R combination, launch the Run menu.
2. Enter “diskmgmt.msc” in the window and click “OK”.
3. See if yours is in the list of connected drives removable disk.

Ideally:

• the connected flash drive is detected;
• all drive partitions have the “Good” status.

In this case, just right-click on the removable drive and select the “Make partition active” option. Additionally, you may need to assign a letter to the flash drive - if this was not done automatically by the system.

The status “Not initialized” or “Unknown” instead of “Good” indicates that the flash drive is faulty; you need to think about recovering the data that was stored on it.

Resetting BIOS Settings

Sometimes the laptop does not see the flash drive due to a failure in the BIOS settings. This can be fixed by resetting the settings to the factory state or manually enabling the USB controller in the BIOS.

After rebooting again, check if the flash drive is detected. If resetting BISO settings does not help, move on to the next solution to the problem.

Removing old USB drivers

Windows installs drivers for the flash drive when it is first connected to the computer. However, after removing the drive, the installed software does not disappear. Moreover, sometimes old drivers interfere with the correct operation of other removable media. To eliminate this influence, you need to update the software of the USB device:

After removing the device, you need to disconnect the flash card and then plug it back in - the old drivers will be removed, and the problem with detecting the flash drive should be resolved.

What to do if the computer does not see the flash drive? Removable drives and HDDs should be extremely easy to use. But sometimes it happens that after connecting an external USB device to personal computer from the operating room Windows system it is absolutely not recognized. If the computer does not see the flash card, this may be caused by problems with partitions on the removable drive, using the wrong file system, faulty connectors, outdated drivers or other reasons.

Below in the text, as well as at the end of the article, you can watch a video why the computer does not see the removable disk. Perhaps you will learn or understand more from it than from the article.

If the PC does not see the flash drive through “My Computer,” then, in the worst case, this may mean that the removable drive has failed and can no longer be restored. Pocket flash drives and large external HDDs work on an identical principle, so the tips listed below are relevant for both types of devices.

What to do if the laptop does not see the flash drive? First of all, you need to find out whether the drive is visible in the disk management manager. Windows Explorer should automatically detect a removable device when it is connected via USB. Insert the disk into the slot. In some cases, to activate an external device, you must press a special button or lever on it. Heavy removable HDDs, unlike flash drives, can even be connected to the mains using a separate power cable, so the computer may not see the external drive if it is turned off.

Now you need to open the Disk Management tool. To do this, press the key combination Win + R, enter diskmgmt.msc in the line that appears and confirm with Enter. Now we can see the external drive in the management window. It should appear here even if it has no partitions.

If you see a device here that is not readable, then you can immediately start formatting it so that Windows Explorer And various devices could access it. If the netbook does not detect the flash drive, then move on to the next section, in which we will try to determine why the drive is not recognized.

Now we need to somehow get Windows Explorer to recognize external drive. It may not be recognized due to a hardware problem related to the computer's USB port. Others possible reasons There may be incorrectly installed drivers or a physical breakdown of the flash drive.

What to do when the computer does not see the flash drive? First, you need to disconnect the drive from one USB port and try connecting it to another. If the removable disk works in the new slot, this means that the problem was a malfunction of the previous one. In case you are using a USB extension cable, try disconnecting it and connecting the flash drive directly to your computer. Such cables sometimes cannot provide the removable device with enough power to operate.

Driver problems

If Windows 7 does not see the flash drive in Disk Management, even after you have connected it to another connector on the laptop, then the problem may be with the flash drive itself or with the PC. If there is another computer nearby, you should try connecting the drive to it to see if it detects it. If a flash drive refuses to work on several computers, then it has most likely become obsolete and must be disposed of. But before making such a sad conclusion, you definitely need to check whether the removable device appears in the disk management window on other computers.

If the drive works on other PCs, or you don't have it on hand additional computers, which can be used, you need to check the relevance installed drivers. This is done using the device manager. To open it, press the key combination Win + R, enter devmgmt.msc in the line that opens and confirm with Enter.

In the list of devices that appears, you need to carefully check all drives for the presence of an icon in the form of a yellow exclamation mark. If you were able to detect such a symbol, then the problem lies with the drivers. Right-click on the device with yellow exclamation mark, select “Properties” and look at the error message. This should help you solve the problem as it can be copied to the string Google search to find reviews from other users who have encountered a similar problem.

Problems like these can be difficult to fix. If the computer does not see the drive relatively recently, you can try running System Restore. But the best way is to use the "Update Driver" button to install latest version necessary software. You can try clicking “Roll Back Driver” in the hope that it will previous version turns out to be workable. You can also use the “Delete” button to external device disappeared from view of the system until the computer was rebooted. It also happens that when you restart Windows flash drive suddenly becomes working.

Partitioning and formatting

If the computer does not recognize the USB flash drive, then the disk management tool can be used to fix partition and file system problems. If you see that the disk is partitioned and full of unallocated space, then you can create a new partition on it. Thanks to this, Windows and others operating systems will be able to work with a flash drive.

Right-click inside the unallocated space, select “New Simple Partition” and follow the further instructions of the program. If the drive is divided into parts, but still does not appear, you need to check whether a specific drive letter is assigned to it. Typically this should happen automatically, but in some cases manual entry may be necessary. Right-click on the removable disk partition, select “Change letter” and enter any free letter. For example, you can write “G:”, and in the future the drive on the computer will be called that way.

If the disk is partitioned, but XP does not see the flash drive, then it is not a fact that the partition was done using the correct file system. For example, a flash drive can be formatted using ext4 for Linux (Linux) or HFS Plus from Mac (Mac). In this case, Windows 10 does not see the flash drive because it is not familiar with such a system. You need to reformat the drive using NTFS or FAT32. Thanks to this, Windows will be able to recognize the flash memory. To reconfigure a partition, right-click on it, click “Format” and select the desired file system.

Please note that this will delete all files on the drive. It makes sense to first connect the flash drive to your Linux or Mac device to copy the data. If you cannot connect a removable drive to devices such as a DVD player or TV, then the reason may be a file problem. NTFS system. The above technique only works with FAT32.
