I just got a Power Mac G4 from a friend and the included DVD-Ram drive does not function, it makes weird noises like the cd/dvd is hitting the inside of the metal case. Therefore I would like to replace it. My question is: Can I replace this mac DVD-Ram drive with any internal DVD or CD drive that uses the molex power supply and SCSI Cable? Or do I need to replace it with the same drive? I have a few DVD drives laying around my work place that would let me have some. I just want to make sure it works before I get one. Thanks!
