Okay, so I got a 17" iMac the other day, installed Jaguar, Office, and some other programs, then put in The Strokes, after which the Superdrive wouldn't read any CDs or CD Roms, but it still reads DVDs. Any ideas why it's doing this? The drive whirs for awhile then ejects the disk again. Is it the music CD's fault? Anything I can do to fix it? I called AppleCare and they didn't have any answers.
