Disk repair

Check and repair a Windows disk safely.

CHKDSK can report filesystem status, repair logical errors and perform a much longer bad-sector scan.

Start with the least disruptive check

chkdsk C:
chkdsk C: /scan

Without repair parameters, CHKDSK reports status. The online /scan option scans an NTFS volume while Windows is running.

Repair options

chkdsk C: /f
chkdsk C: /r
  • /f fixes logical filesystem errors and may schedule work for the next restart when the volume is in use.
  • /r includes /f, locates bad sectors and attempts readable-data recovery. It can take much longer.
Before repair: back up important data. A disk showing physical failure symptoms needs a replacement plan, not repeated repair scans.

With Screensie

PCInfo lists drives and provides a confirmed CHKDSK scan with real progress, cancellation and returned results. A repair that requires exclusive access or restart should be coordinated with the owner.
