Yes, sd0 was a typo ...

I typed:
modprobe st
but again:
[root@asrLXsrv ~]# mt -f /dev/st0 status
/dev/st0: No such file or directory
even if:

[root@asrLXsrv ~]# lsmod

In /dev I've got a lot of "tapXX" like "tap0" "tap1" and so on but I don't think it stands for "tape" ...
Thank you again.

Is the tape drive recognized by the SCSI controller during its BIOS boot scan?

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?

I've no idea why it didn't work for darkmage1975, but I've got a SureStore T20 connected to an adaptec SCSI card and it works fine with 2.6.27 kernel. For reference:
* I've disabled the SCSI host adaptor BIOS because I don't boot from the card.
* tar and mt communicate with the drive fine.
* tar runs much quicker with a larger blocking size specified (-b128) which also seems to make the drive more reliable.
On an Athlon 2200XP CPU you can use software compression without slowing the tape down by adding z to the tar options (if your backup isn't going to need multiple tapes - you can't compress multi-volume archives).
