Yep, tried that. No such device.

Well, yes it did. If I do a tar -tf /dev/st0 I get the list of files that
tar claimed it was writing to the drive, then I get a bunch of errors and
tar exits with the error: too many errors(!). So tar is working to a
point,it just stops arbitarily for no apparent reason. 10240 is just the
block size tar uses by default (20 * 512). I've tried changing the block
size as some newsgroups have suggested with no success.

I've erased the tape, rewound the tape, all successfully. I've done a 'mt -f
/dev/st0 status' and the output looks normal. I'll post the output of that
later when I've got access to the drive.

I'm not really sure about this. How can I tell if the drive is terminating
the chain or not (RTFM)? I just plugged it right in like I would have done
an IDE device. Is there something else I have to do? I admit I know nothing
as far as SCSI goes.

I will keep fiddling, thanks for taking the time to reply.
