CHKDSK : BUG ? KB913034

Our O&O defrag reported chkdsk error this morning on our cluster's data volume.

I run a chkdsk in read only to find out these errors.
Here is an extract of the output:
------------------------------------------------
Replacing invalid security id with default security id for file 1396371.
Replacing invalid security id with default security id for file 1396372.
Replacing invalid security id with default security id for file 1429033.
Replacing invalid security id with default security id for file 1598662.
Fixing mirror copy of the security descriptors data stream.
Security descriptor verification completed.
Windows found problems with the file system.
Run CHKDSK with the /F (fix) option to correct these.
------------------------------------------------

I decided to open a pss call. It's not yet resolved, but we are on this track:
Title:
The Chkdsk.exe utility incorrectly identifies and resets security descriptors in Windows Server 2003

It is possible that chkdsk is reporting false errors. I just send the msrpt cab to pss (see the previous post).
I keep you in touch
