Hey, I just got a macbook (4,1 revision I think, which means it was made early-2008). This is my first time ever getting any apple hardware, and I'm totally lost. It seems that the optical drive is blown, everytime I put a disk in, it scores it along the outer edge. And so I'm looking for a replacement for it, but everything I come up with is for a mid-, or late-2008. Does anyone know the compatibility of these drives? Can I use a mid or late drive in an early-2008 macbook?

I'm also trying to boot into the efi (the mac forums are very specific in saying that efi and bios are worlds apart). If anyone knows how to do that, please pass the knowledge.

FYI: I wouldn't post here if the mac forums weren't crap.
