I gave it some thought and have a game plan. ok so here's the deal. I plan on buying the WD Scorpio Blue 1 TB drive for my MBP 13 inch. Do I need 1 TB? no not really, but if I am going to upgrade my hard drive I want to do it big. And I plan to use this laptop very long so it will accumulate data. So I have a couple questions... 1. What external enclosure should I buy to put my current drive in when I do the swap? 2. I want to start from scratch with the 1TB drive, seeing as I don't have many apps installed right now I can just do it over again. I don't mind. So how do I go about setting it up. After installation of the drive, I just turn on the laptop and pop in the OSX CD? Do I need to press any button as it starts up? Sorry I am a Mac n00b. 3. How do I wipe my current drive completely clean? I want it to be a fresh drive so I can use it as an external when i put it in the enclosure. Thanks!
