The driver's "private" information lives in one (can't remember which off 
hand) of the partition map blocks, after the standard partition map data.
My experience only applies to Apple's SCSI driver, I don't know what
other vendors do. I couldn't figure out why Apple did it that way since
most of the information was based on the partition map data, but their
driver certainly didn't work without it.

Yes, that is all there is to it. But ensuring there is a suitable MacOS
SCSI driver on the disk is probably a Good Idea (tm).
