hi, i just installed windows vista on my mac, for windows programming, but the problem is is that i dont have enough space for both. i would like to get a 500 gb hard drive and i would like to partition it 50/50. i would like to know the proper specs of a 500 GB hard drive that will fit the late 2008 unibody macbook, so if somebody could tell me the specs, or post a link to where i can buy it, that would be well appreciated! thanks in advance!
