hmm try running this line;
Start > Run > chkntfs /x <drive> [drive] [drive]


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.
