Shows or sets whether system checking should be run when the computer is started. The system checking is done using Autochk.exe. The "NTFS" part of the command name is misleading, since the command works not only with NTFS file system but also with FAT and FAT32 file systems..

Must be run with admin privileges.

Example:

$ chkntfs c:
The type of the file system is NTFS.
C: is not dirty.

$ chkntfs /?
Displays or modifies the checking of disk at boot time.

CHKNTFS volume [...]
CHKNTFS /D
CHKNTFS /T[:time]
CHKNTFS /X volume [...]
CHKNTFS /C volume [...]

  volume         Specifies the drive letter (followed by a colon),
                 mount point, or volume name.
  /D             Restores the machine to the default behavior; all drives are
                 checked at boot time and chkdsk is run on those that are
                 dirty.
  /T:time        Changes the AUTOCHK initiation countdown time to the
                 specified amount of time in seconds.  If time is not
                 specified, displays the current setting.
  /X             Excludes a drive from the default boot-time check.  Excluded
                 drives are not accumulated between command invocations.
  /C             Schedules a drive to be checked at boot time; chkdsk will run
                 if the drive is dirty.

If no switches are specified, CHKNTFS will display if the specified drive is
dirty or scheduled to be checked on next reboot.
