Get to the specs of your drive, compare with the specs in amanda.conf, and decide for yourself. > 4.

Look up the spec at HP's website, read the other _examples_, write your own spec. I had to do so for my DLT1 drive -- it was really easy. > 5.

Don't know, sorry. to make devices, cd /dev, sh MAKEDEV. This is a shell script, which you should read for more information. > 7. What's the difference between '/dev/ch0' and '/dev/passX'?

Just having checked the port myself, I believe chg-scsi is broken.

Anybody got this combo out there??? Unfortunately no -- I ditched all that DAT stuff 'cause I was not able to read tape older than a few months back.
