That System Profiler sees it, means at least the interface and other parts of the drive's electronics are working. When you insert a valid DVD and close the door, do any error messages appear in system.log? ...From your description, it's likely that the drive's mechanism has died. Worth looking at the log tho. If there's nothing at all there, then the drive is dead - not even acknowledging the media. >and I pushed the internal PRAM button for 30 seconds while powered >down and plugged in. No difference. That is not a "PRAM" button. That is the CUDA - the Power Manager's hard reset. Press it ONCE then quickly release it, in order to reboot the PMU. Pressing it longer DRAINS the battery. Pressing it more than once can result in a PMU boot failure, which will in turn wipe out that battery also. You should only need to reset the PMU when you make fundamental changes in your system -- like swapping out the CPU or sometimes memory. Note that removing the battery for a few seconds, while the machine is physically unplugged (so no trickle from the power supply), is the same as pressing that CUDA button. It interrupts power flow to the PMU... - Dan. -- - Psychoceramic Emeritus; South Jersey, USA, Earth. -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
