Reasons for USB corruption or inaccessible:

1. Logical Issues
2. Physical Issues

 
Some common physical corruption issues are connecting interruption. The USB port may be damaged because of no power supply. Thus, you should confirm the power supply and try to connect your USB drive to another PC, then replace the USB port. However, if the USB drive is damaged caused by other reasons, you have to take it to a professional repair facility.
 
While if there are some logical software issues with the USB drive, you can quickly fix it. In such a situation, you need to change the USB drive's file structure to make it usable again.

Recovering files from logical issues

Reinstall the drivers

There are times when the drivers that run your USB drive get corrupted and your PC is not able to detect the storage media. If so, you can reinstall drivers by following these simple steps:


1. Right-click "My Computer/ This PC". Click "Manage" and click "Device Manager" on the left side.

2. Double-click "Disk Drives" in the list. Right-click on the name of your pen drive.

3. Click "Uninstall". Click "OK".

4. Disconnect your storage media and restart your PC.

5. Connect your pen drive again. Your PC will detect it and prompt you to reinstall the driver before use.

Repair USB drive by using CMD

CMD is your best choice for damaged USB flash drive recovery. It allows you to fix a corrupted USB drive without formatting and can avoid data loss. In addition, it can also be used to correct the SD card.


1. Plug your USB flash drive or pen drive to your computer.

2. Go to the start menu, type in "cmd" in the search bar, hit "Enter" and then you can see something named "cmd. Exe" in a list of programs.

3. Right-click "cmd. exe" and type in "chkdsk /X /f USB drive letter:" or "chkdsk USB drive letter: /f ", for example, "chkdsk /X /f G:" or "chkdsk h: /f" in the following command windows to start repairing a damaged USB pen drive.
 
This operation will make Windows check and fix the file system on the /flash drive. If the repair process works well, the description "Windows has made corrections to the file system" will appear in the command window. It suggests that the corrupted USB pen drive is successfully fixed and can be reaccessed.
 
However, If the USB drive has bad sectors, your data may be lost during the process of repairing. Therefore, you need to back up or restore essential data from the USB drive before using the CHKDSK command.
