It doesn't look like an issue since the driver is detecting the transfer
rate of 5mb/s, but you could try setting that rate in the SCSI adapter
for that SCSI ID. Also, you might want to see if you can get this tape
drive working on another system.

For someone who avoids SCSI, you sure do have a lot of SCSI controllers
in this machine.
