For example, if you want to disable Chkdsk from running on drive C: chkntfs /x c:
Chkntfs works by modifying the BootExcecute value in the Registry. HKEY_LOCAL_MACHINE\SYSTEM\CURRENTCONTROLSET\
CONTROL\Session Manager
The default value is BootExecute:REG_MULTI_SZ:autocheck autochk *
Chkdsk /f /r is unaffected by chkntfs and can be run to check volumes manually on the next system reboot.
