I am looking at a 500GB hard drive for my MacBook pro and I wanted to check to make sure this will work/fit in the drive enclosure. http://www.cdw.com/shop/products/default.aspx?edc=1436451&enkwrd=ALLPROD:travelstar+5k500 It is a 2.5" but since this will be my first time replacing a Mac hard drive, I am a little wary about it. I have replaced tons on PC's but is there anything I need to look out for? I am contemplating just taking the hard drive to an Apple Store and having them replace it for me. That way, I don't void the warranty because it is not assessable unless you take the entire top piece off (the keyboard). What do you guys think? You have never steered me wrong before.
