OK, swapped out the cable (from an 80- to 40-wire one, as it happened, although that should make no difference on a UDMA33 controller). Same errors appeared again while the backups were running. Some more information on how this drive is being used - we're dumping two vinum RAID5 volumes onto it, one local and one remote, writing to the backup disk over NFS. Both dumps kick off at 0300, with the remote one finishing at 0305 last night. The first ATA error appeared in the logs at 0325, while the local backup was still running. The last error was logged at 0355, but the backup itself didn't finish until nearly 0500. Anyone have any more ideas on how to diagnose this? It does occur to me that the daily periodic run also kicks off at 0301 but that is usually all done before 0330.
