Hey me and my bro are thinking about swapping macbooks over just because of individual needs. They are both core 2 duo 2.0ghz combos but one is pre SR and the other is Santa-Rosa. All I'm wondering is: Is it possible to merely swap over the hard drives or will this be a very bad idea, I'm guessing the latter but worth a shot. One macbook has a 250gb drive the other a 80gb and we still have a spare 80gb drive. We don't want to lose any data and I want to keep my 250gb drive. Can anyone think of a relatively quick way of swapping the HDDs over between the two macbooks. If anyone gets what I'm roughly on about?
