Disable Auto Check Disk on Reboot in Windows XPTopics on this page:
AutocheckIf your computer has an improper shutdown or a hard disc problem Windows may mark the volume as dirty in the registry and set autocheck disk (autochk) to operate on next reboot. Autocheck is a version of check disk (chkdsk) that runs before the system starts. Normally you should deal with the hard disc problem first by letting check disk to run and correct any errors. However, sometimes after checking no problems are found and the same happens on next reboot. Apparently this is a problem more commonly encountered in FAT partitions than NTFS. The fsutil and chkntfs commands can query if a volume is marked dirty. Sometimes when this happens, temporarily disabling hard disc caching may alleviate the problem. There are ways to stop autocheck from happening again. Don't forget to check the Task Scheduler for any entries you made. I've not encountered this problem myself so have not verified the methods below.
MethodsMethod 1: ChkntfsType chkntfs volume [...] in the command prompt to check if volume is flagged dirty. Fig. 1. Chkntfs c: command showing volume c is not dirty. Use the chkntfs command to disable a volume from autocheck with the /x parameter. chkntfs [/x volume [...]] For example, to disable this on C drive, type: chkntfs /x c: Type chkntfs /? for the available syntax.
Method 2: regeditOpen Regedit and modify this (if absent): HKEY_LOCAL_MACHINE\SYSTEM\ Or modify this if the value is different: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Session
Manager\
Method 3: ScriptPrevent Autochk from runningThe following WSH Scipt is taken from Microsoft TechNet. I include the code in full here in case the website is not available for reference. I've not tested it.
Modify the autochk timeout value.This script is again from Microsoft TechNet; the original uses a timeout value of 30 seconds but this can be changed to 0 as in the modified code here.
