DAT 160 usb debian 64AMD mt i/o error

[Hector Arcari]

I have Proliant ml110, DAT 160 usb internal, debian amd64, kernel 2.6.26-1.

mt -f /dev/st0 status
SCSI 2 tape drive:
File number=2, block number=0, partition=0.
Tape block size 0 bytes. Density code 0x48 (no translation).
Soft error count since last status=0
General status bits on (81010000):
EOF ONLINE IM_REP_EN

mt -f /dev/st0 rewind
work OK.

mt -f /dev/st0 fsf 2
mt -f /dev/st0 bsf 2
or any other
/dev/st0: Input/output error
with mt-gnu or mt-st

any idea?
