Meu Problema

My 24'' iMac hard drive went crazy and began a phase of advanced autodestruction.

Minha Solução

The guide is really precise and easy to follow. Some steps are a bit more technical, but the comments help with tips&tricks.

Meu Conselho

Don't hesitate to lever the front panel of the iMac (without pulling too hard on the camera wire), because the bottom of the panel (close to the RAM slot) has a "C" shape that holds the things together.
