It looks like you have a physical corruption on the drive, in the STM file.
You should check the System Event Log to see if there are hardware related
events, especially disk related, etc.. Most likely there is an attachment
affected but not more then that (it is hard to find which message/user at
this point though).
Separate from this, in order to get the database back you can try the
following options (you might want to replace the drive first but that's you
call):
- restore from the last good backup you have. Assuming you don't have
circular logging on (and you didn't delete them manually), you should have
all the logs since the last backup. Before restoring you can take the SG
offline and check them (check if the oldest is since the last backup, run
eseutil /ml e00 to check the logs themselves). I would recommend to make a
copy of the database files as well before the restore (take the database
offline, check for consistent state using eseutil /mh, then copy or move
them). This will be the only solution which will not have any data lost
including the corrupted attachment.
- run an offline defrag on the database. This will keep your attachment
corrupted but will recomputed the checksum and allow backup to keep going.
To do this, unmount the database, check it's consistency (eseutil /mh) and
the run an offline defrag (eseutil /d)
- exmerge all users to a different database, then, once empty, delete the
database (from ESM). This will have the same result as above most likely in
terms of data preservation.
Hope this helps,
