Hi, I'm planning on getting the mac pro after MW SF tomorrow. I know going through apple for hard drives is more expensive and I just happen to have a Serial ATA hard drive from a pc. Looking At OWC's hard drives, It seems to be almost exactly the same as the ones they offer for the Mac pro, Barracuda 7200.10. If i were to format it and plug it into the Mac pro would it work, or do Macs use completely different hard drives than pc?
