There is an article somewhere on the web about this (blog I think) - sorry, no link. It is to do with the way CF emulates IDE protocol and the commands the Apple IDE controller sends to the device. The controller sends at least one type of command that the emulation doesn't support, and this puts the drive in to a state that will not boot.
