I was recently appproached by a client that has an older G4 500 AGP. It came with a DVD-RAM drive installed. She would like to install a superdrive and has seen used ones, pulled from older macs on auction sites such as ebay. Is there any reason why I cannot replace her factory installed DVD-RAM drive with an older model (or current) superdrive? I believe that when this machine was released the superdrive was not an option yet, so is there a firmware update that will need to be installed? The G4 is currently running OS X.2.8. As a follow up question; what kind of DVD-RAM media works in this drive? I have tried (without any luck) Type 2 double sided 4.7GB, and single sided without cartridge. know that it is an older technology, but shouldn't there still be mmedia available for this Apple OEM drive circa 1999-2000? Thanks for any help you have.
