Tape problems

Hi,

	my tape drive is causing problems. It worked fine on a
previous kernel version, but under my current one, it refuses to
co-operate (2.3.13). It's a SCSI tape drive, and responds to SCSI:

root@pick:# scsiinfo -i /dev/nst0

Inquiry command
---------------
<snip>
Vendor:                    HP      
Product:                   T20             
Revision level:            3.010027

But mt fails (as do all other attempts to do something useful with the
drive):

root@pick:/home2/matthew# mt status -f /dev/nst0
mt: /dev/nst0: Input/output error

Any ideas, or do I need a new kernel? I've SCSI support compiled in
(not as a module), and the logs seem to produce no errors....
