Which disk tool for which symptom
| Symptom | Start with |
|---|---|
| Drive is full | Disk Cleanup and Storage Sense |
| File system errors, unreadable files | CHKDSK /scan then /f |
| Bad sectors suspected, slow reads | CHKDSK /r and SMART data |
| Partition or USB stick misbehaving | DiskPart or Disk Management |
| Mechanical drive feels sluggish | Optimize Drives (defragment) |
| Deleted the wrong file | Stop writing and use a recovery tool |
Back up before you repair
Warning: Repair utilities write to the volume. If the data on a drive matters and the drive is failing, image the drive first — a repair pass on dying hardware can make recovery harder.
