New hard drive question
Hey I'm kinda new to the MacBook world and have a stupid question. I am getting a late 2009 MacBook unibody (white polycarbonate, model MacBook 6.1... I believe) I am switching the original 250gb 5400 rpm hard drive out for a Seagate Momentus XT 750gb 7400 rpm hybrid hard drive. I want to keep everything on the original hard drive and just pop the new hard drive and start fresh with Snow Leopard. I'm going to purchase the SL cd from apple but I do not have the original grey start up cd that came with it (my girlfriends little sister lost it). Do I need to call apple for that cd in order to start fresh on my new hard drive or is everything I need on the SL cd?
Also how do I go about wiping the whole computer when I put the hard drive in and use SL? I want to essentially have a completely clean laptop with a new hard drive.
Thanks for your help in advance.
