Here’s what you can try:
- Run CHKDSK: Open Command Prompt as Administrator and type
chkdsk X: /f
(replace “X” with your USB drive letter). - Check Disk Management: In Disk Management, check if the drive shows as “RAW” or has unallocated space. If so, you might need to format it.
- Format the Drive: Right-click the USB in File Explorer and select Format, or use third-party tools like EaseUS Partition Master.
- Data Recovery: Use tools like Recuva to recover data if needed before formatting.
- Test on Another Computer: Try the USB on another computer to rule out PC-specific issues.
