Hello. After looking for advice on forums regarding replacement of the HDD on my new Macbook 7.1, I start to feel both dizzy and confused. I really want to get the 1TB Spinpoint MT2 12,5mm, but there is different opinions everywhere. Some say the WD Scorpio (same dimensions I suppose) will fit all new Macbooks. Some say it absolutely will not. Could anyone here on macrumors be nice and convince me of whats right? Thanks.
