It's the old Unit Attention problem, alright.  Need to cut one wire of
the interface so's it'll work--don't rightly remember which one, though
any local Mac dealer should get it out of Apple Dealer TS if
he/she/it/yx tries a bit.

This is exacerbated by the truly horrid SCSI implementation of both the
drive and the Plus--both of which I use regularly, but have big
problems.

Hope that helps--if not, gimme a call 'n' I'll see if I can dig it up.
