Regular Chkdsk errors on system partition

    Every time I run a chkdsk /f on our system partition (and reboot to allow it
    to run) we pretty much always see some of the following errors:
    Cleaning up x unused index entries from index $SII of file 0x9

    Cleaning up x unused index entries from index $SDH of file 0x9.

    Does everyone get these? Should I try and trace the source?

  2. You're falling foul of a Chkdsk bug in regards to large HDDs.
    Seeing this more often now as the average size of drives grows.

    The CHKDSK utility incorrectly identifies and deletes in-use security

    Thanks for that Henry, very interesting. Also a bit frightening!

    How can I tell if we have actually been affected by this? We certainly do
    not have more than 4M files on the volume, just added-up and only 361,000,
    does that mean that this is not occuring? How can I tell if the master file
    table is larger than 4Gb?

    We have certainly seen a number of ACLs revert to default for no apparent
    reason. Also had a few failure to boot instances after running chkdsk, I
    wonder if this is the reason.

    We are currently running with Win2003 service pack 2 installed so that
    should, theoretically, be using a later (fixed?) UntFS.dll.

  4. to determine size of the MFT table, go to disk defrag on the volume in
    question and select 'Analyze', and then 'View Report'

    In that case we are nowhere near. 4 partitions each around 100Mb for the
    master file table = slightly less than 400Mb in total for the whole disk.
    Does that suggest this is/has not been our problem? If not we still don't
    know why so many directory permissions seem to have been reset to default,
    often after running chkdsk!

  6. Not so much a case of hitting the exact terms of the KB as the KB pointing
    to a bug in Chkdsk that we seem to be hitting more regularly.

    MS probably need to re-evaluate the issue and update the KB, ....and more to
    the point, Fix Chkdsk.

    So do you think it possible/likely that some of our disappearing permissions
    could have been due to the Chkdsk bug even without matching the suggested
    exact criteria?

  8. If the permissions disappeared after you ran chkdsk, I'd say it was most
    highly probable.
    I've seen and heard of at least a half dozen screwed drives due to this in
    the past few months.
