Well I've got the macbook 4,1 the one from the february update, and I've got the 160 GB factory hardrive. And I"m thinking of updating to a 1TB HD. Specifically this one here: http://www.bestbuy.com/site/olspage...T31000333AS+1TB&type=product&id=1186003683968 I've read the reviews on it, and they are mostly good. But I want to know if I can even put a 1TB HD into my macbook. I"m assuming I can since it's just a bigger amount of space. And it does say mac/pc compatible on the specs. So is it pretty safe to upgrade it to 1TB? Thanks in advance!!
