Honestly...I hope for you (Rick) that it solved your problem for good.My 2 cents? It's rather strange that all of a sudden several users complain about this specific error with each it's own different hardware...I use Veritas Backup v10 in an upgrade...
Everybody,my server is encoutering the same problem. Since a few weeks my job stops at the end of the data backup and gives the known error. I already reinstalled my tape drive, changed drivers, changed tapes, ... Sometimes a reboot fixes the problem...
