Ron for what it is worth, i have the same setup (diff drive mfg), but you should use CS on all the drives. I have three HD in my G4 MDD 1.25 and they are all set to CS and work fine. I would say try tial and error with your drive, trying every jumper setting that looks like it should be CS until you find one that works.
