FWIW: We had similar symptoms happening here with an external HP DLT1 drive off a motherboard-internal Adaptec Ultra2Wide controller. The tape was running U2W in single-ended mode and was connected using the HP provided LVD/SE cable. It appears the SCSI bus was too long with that cable. After switching to a shorter external cable (only about 30cm instead of 150cm) all SCSI problems/tape errors disappeared.
