This belongs into the typical group of SCSI1 tape drive problems.
I've fixed this shortly after 3.0R while getting a colleague's machine
up to -current. The drive is working flawlessly again.
NB: I'm not sure blocking the entire `A07:' class of revisions is
either necessary or sufficient (i. e. it's also possible some `A08:'
firmware might experience the same symptoms, or newer `A07:' versions
wouldn't require it -- Tandberg uses 6-char version strings), but it
helped in my case, and i'm positive it'll help you as well.
