I have a 17" iMac 2.0GHz and I love it. Except for the CD/DVD-R drive. For some reason, no matter what I am doing(burning, installing, reading), if there is a disc in the drive it makes this loud obnoxious noise. Kind of like a vibrating. Do they all do this? Does anyone else have this problem? How can I fix it? Ill admit I dont use the drive much but when I do, its really annoying!
