2. Run Windows' repair tool for removable disk

     1. Open "This PC" and find your USB drive.
     2. Right-click your drive and open "Properties."
     3. Click on the "Tools" tab on the top.
     4. Click "Check Now" button (or "Rebuild" button if your system is Windows 10).
     5. Select both options: "Automatically fix file system errors" and "Scan for and attempt recovery of bad sectors."
     6. Click "Start".

 3. Enable USB device and assign a drive letter

This way is effective when the system reminds you of the undetectable drive. Right-click Start and click "Device Manager" (Or go to Start> Control Panel> Device Manager or Right click My Computer/ This PC >>Click Manage>>Click Device Manager on the left side.)

      7. In the pop-up window, click "change." Assign any available drive letter to the USB drive by clicking it.
