I just bought a 500GB HDD for my MBP and I want to install it myself but i don't want to do anything stupid and screw it all up. Should i just take it in to the apple store and have them do it for me. If i do end up doing it myself how should i go about copying my HDD. should i put it in a case, format it and carbon copy. or should i swap out HDs first then install leopard then carbon copy.
