Hi Steve,

I'm trying to get an Exabyte 2501 going also and having a hell of a time.
J"org is working with me trying to get it working and I rebuilt my kernel
with options SCSIDEBUG and booted the kernel with -v.

As soon as the system came up and as root he had me try:

scsi -f /dev/st0ctl.0 -d 255 

and after try some operations:

mt status
mt blocksize 0
mt blocksize 10240
tar c
mt rewind

Maybe this will tell you something in /var/log/messages with the
debug?  I'm new at this, so sorry can't be of much help.

Oh, I called Exabyte and they suggested closing 5&6 on jumper9
to set the blocking to 512 - didn't work...:(

Still trying to figure out what the problem is...
