How to properly clean the registry after the program. Manual cleaning is a risk

All tips

Hello dear site visitors! In this article I would like to tell you about why doesn't the computer see the flash drive?, and what to do to fix it.

Reasons why the computer does not see the flash drive.

Before you decide what to do, you need to understand the reasons, and there can be many of them.

Reason #1. Not connected USB port on the front panel of the computer.

This is one of the main reasons. Most often, people insert a flash drive into the USB port on the front panel of the computer, as it is very convenient. But it happens that during assembly, the craftsmen forgot to connect the front panel to the motherboard. As a result, the flash drive is not visible, and you still cannot insert headphones into the front output :).

Reason #2. Not a working flash drive.

This is the second of the main reasons. Flash drives, like everything in this world, do not last forever, sometimes they break. Most often they burn out.

Reason #3. Virus.

Where would we be without them :). Unfortunately, when transferring data from a computer infected with a virus, two things can happen:

The files on the flash drive will not be visible, I talked about how to solve this problem in this article -
The flash drive itself will not be visible.

Well, your computer may also be infected, and because of this the computer does not see the flash drive.

Reason #4. Driver failure

Driver failures are very rare. However, it does happen.

Reason #5. File system conflict.

It so happens that the flash drive contains a file FAT system, and on the computer NTFS. Sometimes these file systems conflict. Because of this, the computer does not see the flash drive.

Reason #6. Faulty USB port.

Sometimes it is not the flash drive that is faulty, but the USB port itself.

We figured out the main reasons. Now let’s figure out how to make the flash drive visible.

Let's get rid of problems.

Let's decide first problem— The USB port on the front panel of the computer is not connected. Unfortunately, many people cannot solve this problem on their own, because... The front panel is connected to the motherboard, and for this you need to know where to “plug the cord”. If you want, you can call a specialist and he will connect everything for you, it shouldn’t cost much. However, there is an easier way out - connect the flash drive to the rear panel, which also has USB ports.

Problem #2- Not a working flash drive. If the computer does not read the flash drive at all, then most likely it has simply burned out or failed. And there’s nothing you can do about it except throw away this flash drive and buy a new one. But it happens that the computer makes a sound when “inserting” a flash drive, but does not show the flash drive itself. This most often refers to reasons 3,4 and 5.

Let's figure it out with the third problem, that is, with a virus. To do this, you need to check all disks and file media on your computer. That is, we insert the flash drive and check the PC thoroughly. I talked about how to do this in lessons and

Problem number 4– driver failure. But here you have to puff, but in principle it’s nothing complicated.

Specifically in this case you need to update USB drivers port. To do this, you need to go to Device Manager. The most convenient way to do it is this:

You can also open the device manager using the command devmgmt.msc in Run. You can read about how to do this

Now we find the item “USB controllers” and left-click on the small button to the left of this inscription.

We are given a list of all the USB ports that you have on your computer. Next you need to insert the USB flash drive. After this, a change will occur on one of the lines (you will definitely notice it, because the entire device manager will seem to flash). On the newly appeared or changed line, click right click mouse and select "Delete".

With this action, we will remove the driver.

After that, remove the flash drive and insert it again. That's it, we updated the driver.

If updating the drivers does not help, then it may be a file system conflict. Here we are crept up on the fifth problem.

We will solve it by formatting the flash drive in the file system we need.

To find out what file system you have, go to Computer -> Right-click on drive C

Select Properties. And it will show what file system you have.

We will format the flash drive using the program HP USB Disk Storage Format Tool, this program sees the flash drive even when the computer does not see it (unless, of course, the problem is the difference in file systems).

I talked about how to format a flash drive using this program in the article. You can also download this program there. The only thing in the paragraph File system, select the system that is on your computer, in my case it will be NTFS.

well and solve the problem for reason No. 6, easiest. If your USB port is faulty, then you simply try to “stick” the flash drive into other USB ports, and if they do not “function”, there is only one way out - a repair shop.

Well, what to do if laptop Can't see the flash drive? Here everything is even simpler, because there are fewer reasons.

Not a working flash drive.
Virus.
Driver failure
File system conflict.
Faulty USB port.

And you already know how to deal with all this.

Well, that's all. See you again!

A flash drive is an information storage device that connects to any PC via a USB interface. Quite often this device stops working normally. What should I do? Below will be discussed the most effective ways flash drive treatment and corrections typical mistakes when working with the device.

Important!

Follow all the steps sequentially - if the first method does not help, move on to the next one and so on.

What to do if the flash drive stops working

In the modern IT industry, the KISS principle is relevant in a narrow circle, meaning “Keep it simple!” Without special need, there is no need to edit the registry, use complex hardware methods for troubleshooting problems, or try to implement other procedures - you should start with the simplest steps.

Try connecting the flash drive to another PC, laptop or other device to communicate via USB interface. If the flash drive does not work, then with 100 percent probability we can say that this is the problem - and it is necessary to immediately go to utilities for restoring and fixing a flash drive.
If the flash drive works on another computer or is at least detected by Windows (but “Explorer” and “This/My Computer” do not appear), then you need to Troubleshoot problems with the OS or file system using the instructions below.

Disconnect the drive by removing it from the USB connector.
Shut down your PC by selecting the “Shut down” option.
Disconnect the system unit from the 220V power supply, press the power button for 5 seconds - this will remove the residual charge on separate modules motherboard.
Connect your computer to power.
Turn it on, wait until it loads completely and insert the USB flash drive.
Try connecting it to a different connector, especially if remote front USBs were previously used for this task. Optimal option– rear ports
Sometimes the cause of flash drive malfunctions is the assignment of system ID in the form of a letter, or disappearance this parameter at all, to fix an OS problem, use the Disk Management utility

Utilities for flash drive recovery

Be sure to check the flash drive through utility“USB Troubleshooter” from Microsoft – it is not included with the OS, but is available for download from the official portal here free and only works with OS W7 and higher.
It’s easy to use – run the program and click “Next”.

After which the software will try to find and fix typical problems with display of the flash drive in the system.

If you hear a characteristic sound when connecting a device, but it does not appear in Explorer, then open Device Manager.

Often a problem with USB reading flash drives appears after update operating system– it is provoked by incorrect registry entries left after connections physical media information.

Searching for them manually takes quite a long time and is better take advantage special program for searching and clearing non-working keys in the registry.

Best suited for this Vit Registry Fix utility (free and carries out general search and cleaning) And utility USBOblivion (free and clears all data on previously connected flash drives from regedit).
Main advantages: The interface is intuitive and has Russian localization.
Download the program and run it automatic search, after its completion, start cleaning (after checking the boxes in the sections about saving all changed .reg keys in the archive, in order to “roll back” the operation if necessary).

Sometimes the flash drive does not work due to driver incompatibility for USB 2 and 3 versions. IN in this case need to download updated versions on the official website of the motherboard manufacturer.

If the PC does not accept any flash drives, then you need to completely reinstall all drivers for USB drives.

The easiest way to do this is through the “Device Manager” (hold Win + R and enter devmgmt.msc, click on “OK”). Find the “USB Controllers” section in the drop-down list and sequentially delete (right-click on the object, select “Delete”) the subsections USBHostController, GenericUSBHub and USB Root Hub, then update the current hardware configuration and restart the PC.

As a supplement, run full check the entire system.

Launch the registry (hold Win+R, enter regedit and confirm the action by clicking “OK”).
Right-click on the HKEY_CURRENT_USER section and select Find, then type Explorer in the search field. If the folder contains NoDrives, then you need to select and delete it ( Delete button). In addition, in the same registry editor, search for the StorageDevicePolicies parameter (under the HKEY_LOCAL_MACHINE section) and delete it (if present).

Sometimes all the above methods do not give any tangible result.

If the flash drive is identified in the system (at the level of identifying an unknown connected device), then you can try to restore normal work devices, formatting it in a special way using a third party HDD utility Low Level Format Tool .

Work with the device in this case occurs at the level physical sectors, but not file system(as with standard formatting), which guarantees:

Wiping bad sectors
Elimination of any software problems
Permanently deletes all data from the storage device.

The program is free and available for download from the official website. After installing and launching it, select the required drive, click Continue.

Find the Low-levelFormat tab and accept the operation by clicking on Formatthisdevice.
The duration of the procedure depends on the type of flash drive and its capacity, on modern PCs the process takes on average 30-60 minutes. Once completed, you should safely remove the device and restart your computer.

Active PC users often have a problem that the computer does not see a flash drive connected to the computer port. The situation is quite unpleasant... You wanted to copy data from a flash drive to your computer, connected the drive and nothing happens. What should I do? What to do about it?

Reasons why the computer does not see the flash drive

Lack of nutrition

The computer may not see the flash drive if it is connected to the USB port on the front system unit. There may be two reasons for this:

The front ports may not be connected to the power supply;

The front panel ports are receiving insufficient power.

Try connecting the flash device to the USB connector on the back of the computer.

If, after doing this, the computer does not see the flash drive, try connecting it to another computer, preferably not one, but several. If it doesn't help, read below.

Driver failure

The second very common problem is that the computer does not see the flash drive due to a driver failure in Windows. In such a situation, you can try the following:

Right-click on the “My Computer” icon (1), select “Properties” (2) from the context menu:

In the window that appears, select the “Hardware” tab (3) => “Device Manager” (4):

Near the “USB Controllers” item, click on the black plus sign (5). You will see a list of USB device drivers (6) that were connected to your computer:

Insert the flash drive into the computer and see which driver has changed; you need to remove it (right-click on it and select “Delete”).

Remove the flash drive from the computer and insert it back. The flash device driver will be updated.

If the above method did not help you, try reinstalling the chipset drivers. They include drivers for all controllers. The DriverPackSolution program will help you do this.

Presence of a virus on a flash drive

The third quite common problem is that the computer does not see the flash drive due to the device being infected with one of Autorunner viruses. When you try to open a flash device, a warning appears: “Access denied.” To log into the flash device you need to do the following:

Go to "My Computer" address bar(7) enter the address of your flash drive, for example G:/

If you managed to get onto the flash drive, then make it visible hidden files. To do this, click “Tools” (8) in the title bar and select “Folder Options” (9) from the drop-down menu:

Click the “View” tab (10), scroll the slider (11) down and in the settings uncheck the box next to the sub-item “Hide protected system files and folders" (12). Below, check the box “Show hidden files and folders” (13):

Paul - the job is done, now all that remains is to find and delete the malicious autorun.inf file (14):

Done? Now scan the flash drive for viruses with your antivirus (note that the antivirus databases must be updated).

Problems with partitions

The computer also does not see the flash drive due to problems with the device partitions. Let's say you insert your flash device into your computer. It was successfully recognized, a characteristic sound sounded and a shortcut was displayed in the taskbar (15). But the system did not assign a partition letter to your device. This is easy to fix:

Go to the “Start” menu (16) => “Control Panel” (17):

In the window that opens, make sure that in your sidebar it says “Switch to category view” (18). If it says "Switch to classic look", then click on this inscription and you will have what you need. Click on the “Administration” icon (19):

In the window that opens, select “Computer Management” (20):

In the window that appears, select “Disk Management” (21). There you will see everyone present in the system information media: flash drives, hard disks, disk drives and their sections marked with letters. If you find your flash device there (you will see that there is no partition letter (22) next to the name of the flash drive):

This needs to be fixed: Right-click on your storage device. From context menu select “Change drive letter or drive path” (23):

A small window will pop up, in which click the “Change” button (24):

In the new window, select the partition letter from the drop-down list (25):

Mechanical problems

Well, the most recent case is perhaps the saddest. If all the above operations did not save your flash drive, then most likely your flash drive has mechanical damage.

Today, USB is one of the most common data transfer protocols between a computer and a connected device. Therefore, it is very unpleasant when the system does not see devices connected to the corresponding connector. Especially many problems arise if interaction with a keyboard or mouse occurs on a PC via USB. Let's figure out what factors cause this problem and determine methods to eliminate it.

In this article we will not discuss problems with the visibility of the device associated with its inoperability, because in this case this equipment should be replaced or repaired. The article will concern those cases when the problem is caused by malfunctions or incorrect settings system or PC hardware. In fact, there can be many reasons for such a malfunction, and each of them has its own solution algorithm. ABOUT specific ways fix this problem and talk below.

Method 1: Microsoft Utility

In many cases, a specially created utility from Microsoft can solve the problem with the visibility of USB devices.

Method 2: "Device Manager"

Sometimes an issue with USB hardware visibility can be resolved by simply updating the configuration in "Device Manager".

Click "Start". Click "Control Panel".

Come in "System and safety".

Now open "Device Manager" by clicking on the corresponding inscription in the block "System".

The interface will launch "Device Manager". The problematic device in the list can either be displayed in a block "Other devices", or absent altogether. In the first case, click on the block name.

A list of devices will open. Problematic equipment may be indicated there as under its real name, so it appears as "USB Mass Storage Device". Click on its name with the right mouse button ( RMB) and select "Update configuration...".

Device search will be activated.

After it is completed and the configuration is updated, it is quite possible that the system will begin to interact normally with the problematic device.

If the required equipment is not displayed at all in "Device Manager", click on the menu item "Action" and then select "Update configuration...". After this, a procedure similar to that described just above will occur.

Method 3: Update or reinstall drivers

If the computer does not see only a certain USB device, then there is a possibility that the problem is related to incorrect installation drivers. In this case, they need to be reinstalled or updated.

If this option did not help, then there is another method.

Click in "Device Manager" by device name RMB. Select "Properties".

Go to the tab "Driver".

Click on the button "Roll back". If it is not active, click "Delete".

Next, you should indicate your intentions by pressing the button "OK" in the dialog box that appears.

The procedure for removing the selected driver will be performed. Next click on horizontal menu windows by position "Action". Select from the list "Update configuration...".

Now the device name should appear in the window again "Device Manager". You can check its functionality.

If the system was unable to find the appropriate drivers or the problem was not solved after installing them, then you can use the services of specialized ones. They are good because they will find matches on the Internet for all devices connected to the PC and perform automatic installation.

Method 4: Setting up USB controllers

Another option that can help solve the problem under study is setting up USB controllers. It is still performed in the same place, that is, in "Device Manager".

If this does not help, then you can reinstall the drivers for the group elements listed above "USB Controllers", using the same methods that were described in the presentation Method 3.

Method 5: Troubleshooting the port

It is possible that your computer does not see USB devices simply because its corresponding port is faulty. In order to find out if this is so, if your desktop PC or laptop has several USB ports, try connecting the equipment through a different connector. If this time the connection is successful, it means that the problem is in the port.

To resolve this problem, you need to open the system unit and see if it is connected this port to the motherboard. If it is not connected, then connect. If there was mechanical damage or another failure of the connector, then in this case it is necessary to replace it with a working version.

Method 6: Relieving Static Stress

In addition, you can try to remove static voltage from the motherboard and other PC components, which can also cause the problem we are describing.

There is also a possibility that the computer does not see the equipment due to the fact that many USB devices are already connected to it. The system simply cannot cope with such a load. In this case, we recommend that you disconnect all other devices and connect the problematic equipment to the back of the system unit if there is an appropriate connector there. Perhaps this recommendation will help solve the problem.

Method 7: Disk Management

Problem with the visibility of the connected USB device, in this case exclusively a flash drive or external hard drive, can be solved using the built-in tool of the system "Disk Management".

Click Win+R. Enter in the field of the shell that appears:
Apply by pressing "OK".

The tool interface starts "Disk Management". You need to monitor whether the name of the flash drive appears and disappears in the window when it is connected to the computer and disconnected. If nothing new happens visually at all, then this method will not work for you and you need to solve the problem using other methods. If changes occur in the list of connected drives when attaching new media, then you can try to solve the problem with visibility using this tool. If opposite the name disk device there will be an inscription "Not distributed", then click on it RMB. Next, select "Create a simple volume...".

Will start "Master of Creation" simple volume…» . Click "Further".

Then a window will open where you need to specify the volume size. Since in our case we need the volume size to be equal to the size of the entire disk, then click here too "Further" without making changes.

The next window requires you to assign a drive letter. In the corresponding field, select a character that differs from those letters that are already assigned to other drives in the system. Click "Further".

The following settings window opens. Here in the field "Volume Label" You can enter a name that will be assigned to the current volume. Although, this is not necessary, since you can leave the default name. Click "Further".

The next window will provide a summary of all the data entered in the previous steps. To complete the procedure, just click on the button "Ready".

After this, the volume name and status will appear opposite the media name "Fixed". Next click on it RMB and select “Make partition active”.

Now the computer should see the flash drive or external hard disk. If this does not happen, then restart your PC.

There are situations when when opening a tool "Disk Management", the volume that belongs to the flash drive already has the status "Good". In this case, create new volume it is not necessary, but it is necessary to perform only those manipulations that are described starting from point 8.

If, when opening the tool "Disk Management" you see that the disk is not initialized and has a single volume that is not allocated, this means that, most likely, this drive physically damaged.

Method 8: Setting up the power supply

You can solve the problem with the visibility of USB devices by making some manipulations in the power settings. This method especially often helps when using laptops that interact with connected equipment via USB protocol 3.0.

Go to "Control Panel" and then to the section "System and safety". We discussed how to do this during analysis. Method 2. Go here by position "Power supply".

In the window that opens, find the current power plan. There should be an active radio button next to its name. Click on the position "Setting up a power plan" near the named position.

In the shell that appears, click “Change advanced settings...”.

In the window that appears, click "USB Settings".

Click on the inscription "Temporary shutdown option...".

Will open specified parameter. If the value is specified there "Allowed", then you should change it. To do this, click on the indicated inscription.

From the drop-down list, select "Forbidden" and then click "Apply" And "OK".

Now you can check if they will work USB devices on this PC or you need to move on to other ways to solve the problem.

Method 9: Eliminating the virus

We should not exclude the possibility that the problem with the visibility of USB devices arose as a consequence viral infection computer. The fact is that some viruses specifically block USB ports so that they cannot be detected using antivirus utility connected from a flash drive. But what to do in this situation, because if standard antivirus missed it malicious code, then it is now of little use, but you can’t connect an external scanner for the above reason?

In this case, you can make hard check disk antivirus utility from another computer or use a LiveCD. There are quite a few programs designed for these purposes, and each of them has its own nuances of operation and management. But there is no point in dwelling on each of them in detail, since for the most part they have an intuitive clear interface. The main thing when detecting a virus is to follow the prompts that the utility displays. In addition, our website has a separate article dedicated to such programs.

There are quite a few ways to restore the visibility of USB devices in Windows 7, but this does not mean that all of them will be effective in your particular case. Often you have to try many options before finding the right way to solve the problem.
