    • CHKDSK

      The chkdsk or “Check Disk” utility is used in Windows to locate and repair logical file system errors or check the disk surface for physical errors and bad sectors.

      • /f : Fixes errors on the disk. The disk must be locked. If chkdsk cannot lock the drive, a message appears that asks you if you want to check the drive the next time you restart the computer.
      • /r : Locates bad sectors and recovers readable information. The disk must be locked.
