CHKDSK /F or /X Does Not Repair Problems

[John Smith]

The MS Dos commands CHKDSK and CHKDSK /i continually report I have errors
on my ThinkPad A30 HD with a Windows XP Pro preload system that has all the
updates including SP1.

I have been trying both CHKDSK /F and CHKDSK /X to repair whatever the
problems might be now for several tries (via a required reboot), yet CHKDSK
and CHKDSK /i continue to report errors.

Any help would be appreciated as my system seems to getting unstable all of
a sudden.

[Walter Clayton]

Chkdsk can not correct hardware problems. I'd suggest you contact IBM,
especially if the machine is still under warranty.

I am beginning to wonder (if you are the same John Smith who is having
problems with the repair option) if it is something about your vendor,
pre-installed XP system, which, even if it is IBM, is not a true MS
version.

try running chkdsk with the "/r" parameter. this will locate and recover bad
sectors and flag them as bad so that data is no longer written to them.

Nah, nice try .......... but here is the real issue NTSF regarding CHKDSK's
nuisance detections of the Security Descriptors Cache after I searched
Google. This official response from MS was actually posted on this very
same forum about a year ago:

Microsoft FINALLY responded honestly and cogently to my query . . . as
follows:


Dear Jim,

Sorry for the delay. Thank you for your patience with me.

According to my research, I have included the following information for your
reference:
This problem occurs because when 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 is not actually fixing any kind of problem.

Microsoft has confirmed that this is a problem in Windows. Fortunately, this
error message is an informational message, and can be safely ignored.

All NTFS volumes contain a security descriptor database. This database is
populated with security identifiers that represent unique permission
settings applied to files and folders. When files or folders have unique
NTFS permissions applied, NTFS stores a unique security descriptor once on
the volume, and also stores a pointer to the security descriptor on any file
or folder that references it.

If files or folders no longer use that unique security descriptor, NTFS does
not remove the unique security descriptor from the database, but instead,
keeps it cached. Like any caching strategy, you want to keep the cached
information as long as possible because it may be used again.

To determine if more serious problems exist before scheduling or running
Chkdsk.exe with the /f switch, run the "chkntfs <drive letter>:" (without
the quotation marks) command, where <drive letter> is the drive letter of
the drive you want to run the "chkdsk /f" (without the quotation marks)
command against. If this command reports that the "dirty bit" is set, there
may be real damage that needs to be fixed.

I am indeed sorry for the inconvenience that the issue has brought. Please
rest assured that I will not count this case against your free incidents
pool. I appreciate your time, patience and understanding in this case.
