It turns out the SCSI ID of the changer was in conflict with something else, so it wasn't detecting it. I changed the ID and it detected it, so that worked. Running status on the drive, though, still didn't work, until I read this: http://mtx.badtux.net/faq.html Apparently, 'status' is a robotic command, and can't be run on a drive, so it's a *good* thing it didn't work. I still haven't been able to do a successful dump, though, and now I'm having hardware problems with the drive. Thanks for your help. I may be resurrecting this thread when I get my hardware problems sorted out.
