Chkdsk /F does not fix an error

I had a power outage when was defragmeting with O&O defrag the drive C of my WinXP Pro. After restarting Windows the machine came back just fine. Nothing abnormal at all. But I decided to run chkdsk c: /F just to make sure everything was ok. The machine asked to reboot, made all the checks and Windows was up again. Checking the Event Viewer, the WinLogon event just showed that some indexes were fixed. Great. So I did the whole thing again to make sure that this time chkdsk would not find anything wrong. Well, the same indexes again. And the same result after several tries. I try to boot the PC with another WinXP installed in another disk and check that problematic disk again. The same results. Well, how to fix this? The Windows is apparently working ok, but till when? I'm not very comfortable working with this machine knowing that something is wrong. Thanks for your help.

Sometimes I've had to run checkdisk 4+ times before it comes up with no errors.  You might also try booting into the recovery console off your XP CD and doing a chkdsk c: /r
to do a repair of the disk.  This will take quite a bit longer than normal, took me about 3 hours last time, but seems to work for me in the past.

Tried third parties tools mentioned by PeteLong and also chkdsk /r from the recovery console sugested by Eagle6990. I also tryed ghosting the drive to a spare HD and then bringing the image back. Nothing worked at all.

Ultimately It would appear your HDD is not faulty, I've ran HDD's with more than 50% bad sectors and yours is reporting 0% remember chkdsk /r is for loacting bad sectors (and implicitly included the /F switch which fixes errors ON THE DISK)

The fact that you are getting   " 0 KB in bad sectors." indicates chkdsk has done its job :)

and just to set your mind at ease even further
"This problem occurs because if Chkdsk is run against an NTFS volume, Chkdsk.exe may report that security descriptors are in the database that are no longer referenced by any file or folder and that it is removing them. However, Chkdsk.exe just reclaims the unused security descriptors as a housekeeping activity, and it does not actually fix any kind of problem. "

I know this article is for 2K but an ntfs volume is an ntfs volume :)

Thanks for your answer Pete. It's ok, I'll assume that it's everything ok, but I don't remember having those errors before the power outage. So, just to finish this, getting these errors everytime I'll run chkdsk /F is normal?
Pete LongConsultantCommented:
Yes, Dont panic :) All is well with the world ;)
