If a USB drive is not working right, you can try to fix it by following some steps. First, you need to plug the USB drive into your computer and see if it shows up in the Windows Disk Management section. If it is there but you cannot use it, you can try giving it a letter or checking for errors. You can do this by opening the Command Prompt and using the CHKDSK command to look for and fix problems with the files. If the problem is still there, you can use tools like EaseUS Data Recovery Wizard or Recuva to get back the important files before you fix the USB drive. After you have saved all your files, you can try formatting the USB drive to make it work like it used to. If the USB flash memory repair still does not work or your computer cannot find it, the problem might be with the hardware, and you might need to get help from professionals who can fix it.
