Your problem is probably due to formatting the cartridge on the IIgs.
Mac's require a hidden partition which contains the driver. The IIgs
does not place its driver on the media itself but rather it is either
in ROM or in the */system/driver/ folder.

When you formatted using RamFAST you probably wiped out the Driver
Partition. Try re-formatting on the Mac. In the future, if you use
a cartridge on both platforms you will have to format it on the Mac.

Good luck,

Paul.
