Short for check disk, chkdsk is a command run utility that is used on DOS and Microsoft Windows-based systems to check the file system and status of the system's hard drives. The chkdsk command lists and corrects errors on the disk. Used without parameters, chkdsk will display the status of the disk in the current drive. The parameters are as follows:

  • drive : (specifies the drive that you want to chkdsk)
  • /p (Performs an exhaustive check)
  • /r (locates bad sectors and recovers readable information. Implies /p)

On a Unix-based system, the equivalent utility is called fsck.
