Am I correct in drawing the following (pessimistic) conclusion from this discussion?
It is NOT possible to partition a drive in such a manner that
Some partions are in Mac format and can be used to boot the Mac.
Other partitions are in a format that can be recognized and used on a PC.
(Slightly more optimistic
) It may be posssible to share the drive between a PC and Mac if bootability on the Mac is not needed.
