I have an iBook G4 that's running leopard and I have read that replacing the hard drive with a newer one will help the performance a lot. I have replaced the hard drives on a few other computers in the past, but it looks like the iBook is a much more involved process than other laptops. If someone has done this successfully and could share what their process was to accomplish it as well as the difficulty level that would be great. I just want to guage how hard it would be to replace the HD and if I would be able to do it without messing up the machine. Thanks in advance
