I would appreciate some help with a tape problem.
I'm trying to read a 4mm DAT tape. I have a SCSI
tape drive and I get what appears below.

Can someone give me a hint as to what might be wrong?

Can all SCSI tape drive read all 4mm DAT tapes or is
there some formatting issues there?

What do I need to know/do to be able to read this tape
on my system?

Many many thanks.

# mt status
SCSI 2 tape drive:
File number=0, block number=0, partition=0.
Tape block size 512 bytes. Density code 0x13 (DDS (61000 bpi)).
Soft error count since last status=0
General status bits on (45010000):
 BOT WR_PROT ONLINE IM_REP_EN
# cat /dev/tape >au98.0
cat: /dev/tape: Input/output error

and /var/log/messages says

I also tried different block sizes with dd with the same
result.
