Here again!
Well, since the tape drive wasn't recognized at boot time (thank for the hint) I changed the SCSI controller.
Then, here what I get
without a tape inserted :
[root@asrLXsrv sbin]# mt -f /dev/st0 status
SCSI 2 tape drive:
File number=-1, block number=-1, partition=0.
Tape block size 0 bytes. Density code 0x0 (default).
Soft error count since last status=0
General status bits on (50000):
DR_OPEN IM_REP_EN
but if I try to insert a tape:
[root@asrLXsrv sbin]# mt -f /dev/st0 status
/dev/st0: Input/output error
I also tried to use KDAT but it says there's not a tape in /dev/st0 ...
Thank you again in advance for any hint.
PS: I've got also a Surestore DAT40 ... do you know if this is better "recognized" by Linux?
