Nope, never tried it before unfortunately

No. Only the SD's show up.

A "probe-scsi-all" seems to search through the controllers but shows nothing is attached.

Nah there's no connectors.

Hmmmm, good point. I don't really know a heck of a lot about scsi devices so I'm not really sure. The configuration is basically:

(tape drive)(wide-scsi) <<<>>> (thin-scsi)(pci-slot)
