What to do
- Do not format the drive yet, since that can make file recovery harder.
- Try the drive in a different USB port or a different computer to rule out a connection issue.
- Run file recovery software to scan the drive and see if files are still visible and recoverable.
- Copy any recoverable files to a different, healthy drive.
- Once files are saved elsewhere, format the drive in Disk Management to restore normal use.
- If recovery software can't see any files at all, the drive's memory chip itself may be damaged.
Tools and parts
- File recovery software
When to call a pro
If the drive holds files you can't lose and recovery software finds nothing, a data recovery lab can attempt a direct chip read.
