Hello,
- Have you tried plugging the USB drive into different USB ports? If you're using a USB hub, disconnect the USB drive from the hub and plug it directly into your computer to see if it is recognized.
- If the USB drive is detected by your computer, does it appear in File Explorer with a drive letter, or is it missing from there?
Check whether the USB drive is detected in the Disk Management window.
- Press Windows + X, then select Disk Management.
Please post a screenshot of Disk Management showing your USB drive. I'll check it and let you know whether the issue is due to a missing drive letter or a corrupted file system.
