What kind of interface is st0 ?
The drive are LVD. It the tape drive is single-ended (which is what I would
expect for a DLT1), the bus has switched to single-ended, but it's possible
that the drives didn't notice. Usually drives have a jumper to
force to single-ended, and I've got to use it in some conditions.
