hi i own a black macbook. my current drive is FUJITSU MHY2250BH which came with the macbook. I need a biggeer drive, the biggest possible, and I would like 7200rpm as i do alot of audio intensive work etc and really push the laptop. i found a 500gb fujitsu, but the dimensions are slightly diff to my current drive. should i make sure the dimensions are exactly the same? eg to the millimetre?? i just want to know about what specs to watch out for. i live in uk, so dont really want to buy from a usa retailer. can anyone help? thankyou also, would i be able to use my current drive as an external drive? how could i plug it into macbook? an enclousre? or just a wire? i also have a bootcamp partition currently. would the new drive be a simple change over? ie. no need to reinstall any app or boot camp from scratch again? i think i read that we can just use a time machine back up to put my current macbook drive state onto the new drive.....right?
