In need of help! Despite being female I am sometimes able to perform self-taught technical miracles! But this time I am in the dark. My CD drive on my old mac book 1.1 is rarely working now so I guess it needs replacing. I read that its best to buy one online and either fit myself or take to a repair shop, rather than face high costs of mac repair shop. I did loads of research online but still very confused. Which one do I need to buy exactly? I saw some on EBay but no idea which one to choose. Can anyone help? Thanks!
