varying CHKDSK results

This is on WinXP Pro SP 2.

Today I ran CHKDSK on my Raid 0 Array for the first time in a very long
time from the disk properties on re-boot. Many many Invalid Security
Descriptors were found and replaced with default values. OK, didn't seem
to do any harm. That was early this afternoon.

Now I decided to run CHKDSK from a command prompt without the /F to see
if it was OK.

3 successive runs produced these results

Dave, these are twin Western Digital WD25000JB drives in a RAID 0
configuration. I've tried the WD Diags for the drive and it seems they
don't support RAID configurations, only discrete drives...

Also, I rebooted and my varying results went away. I'm left with this
problem only,

Correcting errors in the master file table's (MFT) BITMAP attribute.
CHKDSK discovered free space marked as allocated in the volume bitmap.

If I run CHKDSK /F and allow CHKDSK to run on boot, it find nothing
wrong. However, running CHKDSK from a command prompt always gives the
above error.

I've seen other people with the same problem in searching the web. It
could be a WinXP NTFS problem?

You should not give credence to these "errors" that show up when running
chkdsk without /F from within windows. If running a chkdsk /F which will
only happen for the boot volume after a restart, doesn't show any problems
then don't worry about it. Chkdsk when run from within windows is
unreliable as an indicator of problems.

Now I decided to run CHKDSK from a command prompt without the /F to see
if it was OK.

Using chkdsk with no switches is the same as running in read-only mode.

Don't even bother running CHKDSK in read-only mode. It is a waste of time
and prone to not accurately reporting information. CHKDSK might report
spurious errors because it cannot lock the drive.

[[Chkdsk might not accurately report information in read-only mode.]]
From...
Chkdsk
http://www.microsoft.com/resources/...windows/xp/all/reskit/en-us/prmb_tol_pwfd.asp

[[If you run chkdsk without the /f command-line option on an active
partition, it might report spurious errors because it cannot lock the
drive.]]

[[Using chkdsk with open files
If you specify the /f command-line option, chkdsk sends an error message if
there are open files on the disk. If you do not specify the /f command-line
option and open files exist, chkdsk might report lost allocation units on
the disk. This could happen if open files have not yet been recorded in the
file allocation table. If chkdsk reports the loss of a large number of
allocation units, consider repairing the disk.]]
From...
Chkdsk
http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/chkdsk.mspx

[[In read-only mode, CHKDSK quits before it completes all three phases if it
encounters errors in earlier phases, and CHKDSK is prone to falsely
reporting errors. For example, CHKDSK may report disk corruption if NTFS
happens to modify areas of a disk while CHKDSK is examining the disk. For
correct verification, a volume must be static, and the only way to guarantee
a static state is to lock the volume. CHKDSK locks the volume only if you
specify the /F switch (or the /R switch, which implies /F). You may need to
run CHKDSK more than once to get CHKDSK to complete all its passes
in read-only mode. ]]

Now I decided to run CHKDSK from a command prompt without the /F to see
if it was OK.

Using chkdsk with no switches is the same as running in read-only mode.

Don't even bother running CHKDSK in read-only mode. It is a waste of time
and prone to not accurately reporting information. CHKDSK might report
spurious errors because it cannot lock the drive.

[[If you run chkdsk without the /f command-line option on an active
partition, it might report spurious errors because it cannot lock the
drive.]]

[[Using chkdsk with open files
If you specify the /f command-line option, chkdsk sends an error message if
there are open files on the disk. If you do not specify the /f command-line
option and open files exist, chkdsk might report lost allocation units on
the disk. This could happen if open files have not yet been recorded in the
file allocation table. If chkdsk reports the loss of a large number of
allocation units, consider repairing the disk.]]

[[In read-only mode, CHKDSK quits before it completes all three phases if it
encounters errors in earlier phases, and CHKDSK is prone to falsely
reporting errors. For example, CHKDSK may report disk corruption if NTFS
happens to modify areas of a disk while CHKDSK is examining the disk. For
correct verification, a volume must be static, and the only way to guarantee
a static state is to lock the volume. CHKDSK locks the volume only if you
specify the /F switch (or the /R switch, which implies /F). You may need to
run CHKDSK more than once to get CHKDSK to complete all its passes
in read-only mode. ]]

Wes, thanks for the info and pointers. I had looked at some of those
same pages and dismissed them, as I didn't fully read the little bits
you pointed out.

Running under boot-up shows no errors. Good enough for me, thanks again.

After backup you can run
chkdsk /r
from the recovery console command line. (/r implies /f and /p)

To start the Recovery Console, start the computer from the Windows XP
CD-Rom. At the "Welcome to Setup" screen. Press F10 or R to repair a Windows
XP installation, and then press C to use the Recovery Console. The Recovery
Console then prompts you for the administrator password. If you do not have
the correct password, Recovery Console does not allow access to the
computer. If an incorrect password is entered three times, the Recovery
Console quits and restarts the computer. Note If the registry is corrupted
or missing or no valid installations are found, the Recovery Console starts
in the root of the startup volume without requiring a password. You cannot
access any folders, but you can carry out commands such as chkdsk, fixboot,
and fixmbr for limited disk repairs. Once the password has been validated,
you have full access to the Recovery Console, but limited access to the hard
disk. You can only access the following folders on your computer: drive
root, %systemroot% or %windir%
