Hey guys! I have a Rev. A MBP with the 2.16ghz Core Duo with 2gb ram and upgraded to Scorpio 320gb hd. My superdrive (the first 4x version) has decided to go crazy on me. Not only this, but I need the capability to burn dual layer dvd's for backups. I need to replace it. Since I'm "newer" to replacing mac hardware, will any Superdrive work/fit in my Rev A? It has the original Matshita UJ-857 Thanks!
