I just replaced my HP tape drive with Tandberg LT04. It was recongnized fine with backup exec, I labeled and formatted the tapes just fine. When backing up to it, it just fails with unknown error. I triedn installing and reinstalling, different drivers, and it is always the same thing.
Storage device "TANDBERG 0001" reported an error on a request to write data to media.
A device attached to the system is not functioning.
