I have just had my 40gig HD replaced by an 80 gig Toshiba. I didn't want to risk my Applecare warranty, so I paid for a licensed Apple tech to make the swap. Ouch! it cost $120. I would like to swap the 40gig into my old 400MH 10gig Tibook, and would like to try to do this myself. I have the instructions from Apple, but the diagrams for some of the processes are a bit sketchy. Does anyone know if there are photographs of this replacement?
