I did my weekly cleanup this morning on finishing I ran chkdsk /r. I rebooted the system and the message "cannot unlock volume" came up. I tried again with chkdsk /f and got the same message. I have done this everyweek for over a year and have never had a problem. Any ideas?

do a system restore prior to your last clean up.

Running Mcafee or Norton?

run chkdsk in save mode some background process is locking the volume from changes.

Did system restore. Same problem.
No Mcafee/Norton. Will try safe mode later.
Thank you all for the advise

If you were to read the rest of the
error message, it would be asking
you if you wanted to schedule
Chkdsk to run the next time you reboot the
computer. Simply
select this option, and then shutdown and restart the
(Chkdsk cannot scan a partition that's in use, so it has to

scan the system partition at reboot, before Windows

another thing to try boot in to safe mode and try last known good configueration

stalion. Thank you, but to be honest this was the first thing I tried when the problem arose

Jaro. The message appears after I re-boot and the chkdsk window appears

Windows XP chkdsk needs to have exclusive access to your volume to run properly. That's why its done usually during boot up, before the windows system or other programs start accessing your volume.

In your case, during this start up routine, some program has already started accessing your drive, denying the access that chkdsk needs.

You might want to try disabling some of your automatic startup services or programs to pinpoint the culprit. The most common ones would be virus scanners, or any programs that deals with the hard disk (monitoring, back up and recovery, etc..)
