Re: What do these chkdsk errors mean?

We looked at another similar problem in this newsgroup at the end of
July but I do not think the discussion reached a conclusion. I found
this Knowledge Base Article but the example under query did not seem to
fit the criteria.
The CHKDSK utility incorrectly identifies and deletes in-use security
descriptors
http://support.microsoft.com/default.aspx/kb/831374/en-us
Your example clearly does not meet the number of files criteria? You do
not mention the size of the Master File Table.
It's speculation on my part but I wonder whether the problem is simply
the result of corruption of the Master File Table.

Hello,
i had some weird chkdsk errors when running from within Windows (in
read-only mode), about finding errors and trying to recover lost data.
So I ran chkdsk with /r, and restarted and it went through the long
process. This is what it came up with:
Checking file system on C:
The type of the file system is NTFS.
A disk check has been scheduled.
Windows will now check the disk.
Cleaning up minor inconsistencies on the drive.
Cleaning up 5 unused index entries from index $SII of file 0x9.
Cleaning up 5 unused index entries from index $SDH of file 0x9.
Cleaning up 5 unused security descriptors.

Windows has finished checking your disk.
Please wait while your computer restarts.
I then checked an earlier chkdsk /f report that I did an hour before
the /r report posted above. it stated the following:
Windows will now check the disk.
Cleaning up minor inconsistencies on the drive.
Cleaning up 832 unused index entries from index $SII of file 0x9.
Cleaning up 832 unused index entries from index $SDH of file 0x9.
Cleaning up 832 unused security descriptors.
CHKDSK discovered free space marked as allocated in the
master file table (MFT) bitmap.
Windows has made corrections to the file system.
So it apparently found some errors, and after running chkdsk in
windows
again, I went back and did an /r and it found more errors. The only
error unique to the first check is the one about free space marked as
allocated in the MFT bitmap.
Is there any reason to worry about the errors? This is a brand new
hard drive, so i was surprised to see errors so soon.
Thank you very much for any insight you can offer!
