[G4] (no subject) How to use multiple drives.

[Steve Goldstein]

Refers to one implementation of the IDE bus.  Room for two [Parallel ATA]  drives on each arm of the bus (that is, on one ribbon connector).  One drive was to be designated designated "master," and the other one "slave."  That was mainly in the PC world.  Another implementation just left them both as "cable select."  I believe, but am not really sure, that most Macs support cable select.  Each drive will have different jumper configurations (meaning how you use tweezers and a magnifying glass to place a little short-circuiting jumper onto two pins on one end of the drive) to make the drive recognizable as master, slave or cable select (other choices also exist for many drives).  I also believe that if your Mac supports cable select, you could also use the master/slave config, as long as one is master (may have to be the furthest connector from the mother board on the cable) and the other slave.

HTH,

--Steve (who is rusty about the details, because it has been a long, long time since I configured a Parallel ATA HD.  No need to worry about these niceties with SATA drives.)
