Try this >>
Windows XP
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.
To restore the automatic execution of Chkdsk, you can download and run this registry file (168 bytes).
