this is driving me crazy, mostly because i'd like to check apples discussion board for an answer to this but it's been dead for a day now. anyway, here's the problem: G4 933 w/ superdrive, OS 10.2.8 salesman asked me to copy some audio cds for him, put the first one in. "the best of the squirrel nut zippers". it's got audio and multimedia content (macromedia and quicktime). nowhere on the disc or jewel case does it say copy protected or anything out of the ordinary. ripped tracks to aac format in itunes. inserted blank cdr (which salesman provided, gold memorex cdr that apparently is a couple years old). itunes begins burning but never gets anywhere. after an hour decide to force quit and try again. had to restart the computer. cdr doesn't seem to have anything burned on it, but try a different disc anyway. same thing. gave up and went back to work. suddenly, my superdrive won't recognize data cdrs that customers send to us. also won't recognize the jaguar install cd, norton utilites or diskwarrior. basically it doesn't see cdroms AT ALL. dvds, however, mount and are accessible as normal. the superdrive shows as normal in system profiler. ran permission repair, started up G4933 in firewire target mode from 12" powerbook, can run permission repair and can run diskwarrior on the G4933 but cannot rebuild the directory (it's grayed out). rebooted G4933 as normal. restarted and zapped the pram. so far nothing is working. any ideas?
