hey guys, apologies if this has been asked before, but since hard drives change all the time i figured an updated thread couldn't hurt. i'd like to upgrade my macbook's hard drive (white 2007 macbook). my current drive is a 120 gb fujitsu (stock). i have 2 questions: 1) which specific hard drive should i buy? i'm thinking around 250 gb would be perfect, and i don't want to pay more than i have to. that said, i'm willing to pay what i need to pay for a good hard drive that will last. anything off ncix.net or tigerdirect suits my fancy. 2) i still have another year of my applecare. is there any way to upgrade the hard drive without voiding my warranty? or, am i missing some other crucial detail here? thanks guys - again, hopefully this question hasn't been asked and answered a thousand times... i couldn't find any threads with specific answers.
