I'm not sure if this was just a means for Apple to sell drives; because
according to some official Apple tech notes I read somewhere, it was
necessary for a while for them to develop custom firmware for each
drive. This firmware can be thought of as the device driver for that
hard drive, part of the OS after a fasion. Maybe it took a while for
hard drive manufacturers to figure out how to be interchangeable,
so that a "universal" driver was possible? How new was the SCSI spec
when Macs first started using it?

OK, here is a very elementary question that has
always
stumped me. Is there any difference between an external
SCSI hard drive made for a Mac and a generic SCSI hard
drive? Can I hook up a Mac SCSI hard drive to some other
computer with a SCSI interface and expect it to work (after
formatting, of course)? What about the other way around?
The first alternative works very well indeed. The second won't, though.
Macs use hard drives with a particular Apple firmware, without which HD SC
Utility won't recognise the drive. Bloody stupid. Another Apple
