Apparently a physical I/O error from the hard disk. I would capture a copy of the latest backup file (DCO backup file) as soon as possible. To have a reliable setup, I would then reinstall DCO (including restoring the backup file) preferably on a new disc (if the current disc is having hardware problems).
