I've got a 1.5Ghz, 80g hard drive Powerbook G4 with a MATSHITA DVD-R UJ-835E DVD/CD Superdrive. When I'm inserting a disc into my Superdrive, it physically moves the right side of my keyboard up a little bit. Then, after a minute or two it makes a clicking sound and ejects my CD/DVD without reading it. I am wondering if my Superdrive is going to need replacement or if there is something else that I can do to remedy the problem. Thanks for the help!
