Do not run eseutil or isinteg (or any other utility) on your database files.
- Check your system event log for any disk-related errors. Chances are excellent that these errors are what are causing the Exchange database errors.
- Check your backup by restoring it to a recovery server. Check the recovery servers event log for errors.
