Has anyone used one of the SCSI removeable hard drives for both a Mac and a PC? Clearly you need differently formated removeables. Who supplies both cables and the necessary formatting software for each format? Any sucess stories (at worst, failures) in doing this? Michael Slade slade.wbst128@xerox.com

I have been told that most PC controllers do not use parity while the mac does. Consequently you would need to be able to switch parity on and off on the drive easily.

I didn't have time to check it yesterday.

I've moved a Syquest drive back and forth between a Mac and a PC with no problem, using different cartridges for each. As far as parity goes, things are more complex than some of the messages here have indicated. Some messages have talked of devices "using" parity. It is better to talk of devices generating parity and devices checking parity. For example, when you remove the parity jumper on a Quantum drive, the drive stops checking parity, but it always generates parity. There are three combinations that appear in practice: generate and check generate but don't check don't generate and don't check (Has anyone seen a device that checks but does not generate parity?) I don't have my references with me, so I can't be certain, but I believe that the Mac falls into the "generate but don't check" category. Tim Smith
