I've been seeing more and more hard drives coming out with built in encryption, but so far, they only have Windows support. I assume they mean "PCs with BIOS" when they say Windows, since you have to unlock the hard drive before any OS starts.
Does anyone know of any of these hard drives that can work with EFI based computers, such as a MacBook Pro? Or maybe a EFI extension that allows the hard drive password to come up? I suppose it is possible since Apple and others have made EFI extensions to emulate a BIOS for Boot Camp.
