Hey all. I have a quick question that I need help with. I have an early 2008 MBP and have replaced the hard drive with a 320GB 7200RPM drive. I know this will void the AppleCare warranty if Apple finds out I did it. I kept the original drive as a bootable backup and to swap back into the machine in case I need to send it back to Apple for repair (so they don't know the drive has been swapped). ATM I am in need of a laptop HD (my PS3 needs a larger drive) and I am tempted to use the old drive from my MBP, but I want to make sure that I don't need it as a swap in case of MBP repair. Basically, I am trying to find out if I should keep the original drive or not. I have read on this very forum that you should swap the original drive back to be safe when sending out your MBP for repair. I have also read (also here) that it doesn't matter. Then I've read stories of how Apple sent back their systems with a brand new stock HD and they lost they one they installed into their MBP. I'm just trying to get a straight answer on this as I just bought and registered my AppleCare warranty today. Thanks ahead of time for the help.
