We have a Backup Exec 8.0 server backing up 4 jobs per night to a DDS4 tape drive. Over the last week the jobs have all started and then get partway done and stop and fail with "device is not ready" as the error in the log. I have cleaned the tape drive several times, rebooted the server, and the tape drive does not appear to be the problem since the job will fail with that error, and then the next job scheduled later will start normally until it fails with the error after backing up some of the data. I found a "device not ready" article on veritas.com but it only deals with the job never starting, any ideas why it would keep doing it during the job, yet start the next job normally? The jobs are all spaced out so that they do not run into each other.
