I have a superdrive in my G4 PowerMac 1.42Ghz DP. Suddenly it will not mount blank media! Whenever I insert a blank CD or DVD it does not mount anywhere. If I put in a burnt CD-RW I can erase it via Disk Utility but once it is blank I still cant mount. Any ideas anyone. It is the first problem I have had with this Mac and it is damn annoying!
