Ok, here is what I have tried finally.  Trying to get amtapetype to work.

[EMAIL PROTECTED] ~]# mt -f /dev/nst0 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

[EMAIL PROTECTED] ~]# mt -f /dev/nst0 offline
/dev/nst0: Input/output error

[EMAIL PROTECTED] ~]# mt -f /dev/nst0 load
/dev/nst0: Input/output error

[EMAIL PROTECTED] ~]# 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

[EMAIL PROTECTED] ~]# mt -f /dev/st0 load
/dev/st0: Input/output error

Here's what the log says

Sep  8 13:30:50 localhost kernel: st0: Error with sense data: <6>st0:
Current: sense key: Not Ready
Sep  8 13:30:50 localhost kernel:     Additional sense: Medium not present

Any ideas?

Thanks alot

Nick

You figured wrong.

mtx works on the robotic changer mechanism,
st0 is a tape drive inside your changer.

mt is for manipulating tape drives.

I have two tape drives, and standalone Ultrium and a DDS 3 changer.
mtx -f /dev/st<whatever> does nothing useful on my system.
Doesn't give an error, just hangs.

Does anything do anything with your tapedrive?
Can you tar to it?  tar from it?  dd to or from it? cat to or from it?

bacula may be a fine product.
But unless you can access your tapedrive with some basic commands
no backup product is going to do diddly.
