I bought an old iBook G4 for a few coins because I was curious. This is my first Mac experience. If it wasn’t here on my desk, I would not believe it. On an ordinary notebook you need 3 screws for a drive replacement (max), this has 42 steps and one of the steps alone has 15 screws. Guess what is wrong with the iBook I got? The hard drive and the optical drive :) No problem, I have spare hard drives… This walkthrough is a must have for me.
