I read somewhere that a firmware update for the superdrive created enomolous errors. Is there a way to step back to the original and to block the update? What I get is both of my supperdrives act up in my mac pro. One superdrive refuses all burned disks and kiks em back out. The originals are fine but sometimes i get an error of no software to install like with my i life disk. Second try it installed fine. Same with Leopard install it took two pass to install. First time it ended with clean disk and restart try again. I did not clean anything just restarted and finished the install. Also the other drive I install a burned disk and it thinks I installed a new blank disk and it tells me to format it to burn data disk. Is this some kind of trick to destroy my burned disks?
