ChkDsk Runs On Every StartUp.

If your chkdsk runs on every boot, here are some things you can try. First of all, let it run once completely.

Then try this : Run regedit Edit: HKEY_LOCAL_MACHINE\SYSTEM\ CurrentControlSet\ Control\ Session Manager Change the BootExecute entry from: autocheck autochk * /. To: autocheck autochk *   Or else try this : Start> Run> bring up a command prompt by typing in “ CMD” and type ” fsutil dirty query g: “ . This queries the drive, and more than likely it will tell you that it is dirty. Next, type “ CHKNTFS /X G:” . The X tells Windows to NOT check that particular drive (G) on the next reboot. At this time, manually reboot your computer, it should not do a Chkdsk and take you directly to Windows.   Once Windows has fully loaded, bring up another CMD prompt and type and now you want to do a Chkdsk manually by typing “ Chkdsk /f /r g:” . This should take you through 5 stages of the scan and will unset that dirty bit. Finally, type “ fsutil dirty query g:” and Windows will confirm that the dirty bit is not set on that drive.   You can run the chkdsk /r command or the chkdsk /f command to check a hard disk for errors. But if The “ chkdsk /r” command and the “ chkdsk /f” command take a long time to run on a Windows Vista-based computer see this KB943974 Article.
