Okay several things.  I mislabeled this post.  It's an 80-pin drive.

I bought an adapter in August that was 50-pin, 68-pin and 80-pin.  I last week bought a 68-pin to 50-pin adapter.  Neither have worked.

In SCSI Probe with the CD Drive, only the CD Drive shows up, sorry.

Well actually both the adapter and also the drive itself [have termination power options and lack terminator resistors].  But I meant the drive; the 80-pin Compaq has a SCSI Termination jumper option but lacks the socketed resistors present on all the 50-pin drives I have.

I have a Quantum ProDrive 40S from an SE/30 that doesn't mount or read properly but is terminated properly [as far as I can tell; or should be].  With options [on Compaq]: ID1, ID1 & Disable Target Initiated Synchronous/Wide Negotiation, and ID1 & Termination Power jumpered, only the Quantum shows up.

I'm at a loss.  The options on the drive itself are Termination Power / SCSI Termination / Disable Target Initiated Synchronous/Wide Negotiation / Disable Unit Attention / SCAM / Delayed Start / Disable Auto-Start / and the ID options.
