121. How Do I Prevent CHKDSK From Running Every Time My PC Starts

When your PC shuts down without warning or it has to be shutdown because of problems you may find, that on rebooting, the AUTOCHK application will start up and check your disk for errors. This can be tiresome, particularly if it occurs every time you boot your machine. To disable this feature do the following.

Click the Start Button.
From the Start menu click Run.
In the Run dialogue box type: cmd.
The command prompt window will now open.
In the command prompt window type: fsutil dirty query c: (If you have a dual boot system then replace the C: drive letter with the relevant drive letter you have been having problems with).
Press Enter.
The response from the file system utility will probably be that the disk is 'dirty'.
Now type: CHKNTFS /X C: into the command prompt window and press Enter. (If you have a dual boot system then replace the C: drive letter with the relevant drive letter you have been having problems with).
The X parameter, in this case, tells windows not to check the disk in question.
Next manually re-boot your pc.
You should now find that CHKDSK does not run on the selected drive.
Once you have confirmed that CHKDSK does not run and your PC has fully booted click Start>Run again and type cmd.
In the command window now type: chkdsk /f/r c: and press Enter. Again replace the C: (If you have a dual boot system then replace the C: drive letter with the relevant drive letter you have been having problems with).
After the drive has been scanned type: fsutil dirty query c: and press Enter.
Windows should now confirm that the 'dirty bit' has been disabled.
