Problems With Windows XP Check Disk

“…there appears to be a problem with chkdsk recording false positive errors when run from a command prompt. I can find no reference to this problem in the Microsoft Knowledge Base. To quote from this article reportedly sourced from Microsoft, ‘This problem occurs because when chkdsk is run against a 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 housekeeping activity, and is not actually fixing any kind of problem.’

Thus the instruction given by chkdsk to run chkdsk with the /f fix option to correct these errors can be safely ignored, but only in certain circumstances. There are many reports in web forums of poor souls doing high and low level formats, ASR restores, changing hard disks, etc and generally pulling their hair out, all to no avail because of this bug in chkdsk.”
