Is Case Cause of stuck DVD?

I have seen this on my iBook G4. Pressure on the case from being in a backpack caused the DVD drive slot to sag and compress in a bit. I took a wide flat head screwdriver and stuck it in to the drive case just a bit. Make sure you get past the plastic part because it is actually the metal part that is bent. Slowly and gently twist the screwdriver to open up the case enough to let the disc eject. It helps if you turn the computer on it's side and let gravity assist.

Another way to do it, is wait until you have the iBook apart, remove the superdrive and unbend it then. The CD should come right out.

Here is a link to some older questions about this subject.

Good Luck, love the iBooks
