My iPod's hard drive is broken. Only about 1.7 gigs can be read and the other part doesn't work. It fell out of the car when I was getting out. My iPod is out of warrantie and I would rather get a new 10 or 20 gig drive than pay apple to fix it. I know that the 10 gig drive is just as thick as the 5 and the 20 is thicker. Could I put a new drive in myself? Could I fit a 20 in or would it be too thick? and where can I buy one of those drives?
