I have done this in the 500mhz ibook (the first non clamshell ibook) It was about as intense as a 2400c disassembly to change processors. It really is not hard, just time consuming, and lots of parts and screws to keep up with. My ibook is out of warranty as I did not purchase applecare. It is also not my main computer. I had little to lose if I got it all back together and it did not boot for some unknown reason. I installed a 40gb ibm fluid bearing drive. I used these instructions... http://www.yourmaui.com/ibook.html On 12/3/02 9:03 PM, "Chris Volpe" <absinthe02 at attbi.com> pecked this out: > Greetings iBook listers! > Since the question of upgrading hard drives in older 'Books has come > up, I wonder if anyone has any experience with doing that on the newer > (non-clamshell) models.
