A logical disk has a dirty bit set

  wrg 19:33 05 Oct 07

I have ran a reliability and performance check on my lappie & am getting the above error message. Can anyone tell me what it is,and also getting "a service is reported as having an unexpected error code with a code not equal to 0 or 1077". If I click this link it takes me to MS website but cannot understand it.

This will tell you more click here

You can check to see if your drive is definitely flagged by opening up a CLI Window (Start menu -> Select Run -> type in CMD)

Now type in the following:

FSUTIL DIRTY QUERY C: (followed by the enter key)

(assuming that C: is your boot drive)

If it tells you that your drive is dirty then...

Go back to the CLI window and type in the following

CHKNTFS /X C: (followed by the enter key) - This will stop the disk check on the next reboot

Now reboot your computer: let it reboot and open up another CLI - type in the following:

CHKDSK /F /R C: (followed by the enter key) - Let is scan and check your computer fully

Once it has done so type in the following again as in the first step


The drive bit will be set to clean again

Be aware the checking can take some time so ensure you are on mains with no shut down set for period of non-use. DO NOT interrupt the process as you could easily make things worse.

Find this very strange, but glad the problem has gone. Have you carried out a virus scan in the meantime?

not yet. Trying to solve another problem with an abnormally stopped system service. Trawling the net trying to find how to solve it.
Its a UPnP device host error, any ideas?

Sorry can`t help there. Perhaps if you start a new thread with full details of the problem you will get a good response - plenty of varied experience and knowledge on this forum.

johndrew. Thanks for you input. Did a clean install in the end. I think the problem related to some software that I loaded on my system. It was Sony Handycam S/W. When I tried to use it I was getting errors saying I could not use USB. I tried to uninstall it but it would not fully uninstall. Further investigation pointed to a problem occuring with USB being stopped at start up.
