Five ways to eject a stuck CD or DVD from the optical drive
Ejecting the stuck disc can usually be done in one of the following ways:
1. Restart the computer and after the chime press and hold down the
left mouse button until the disc ejects.
2. Press the Eject button on your keyboard.
3. Click on the Eject button in the menubar.
4. Press COMMAND-E.
5. If none of the above work try this: Open the Terminal application in
your Utilities folder. At the prompt enter or paste the following:
If this fails then try this:
Boot the computer into Single-user Mode. At the prompt enter the same command as used above. To restart the computer enter "reboot" at the prompt without quotes.
Was it also a 'non-standard' shape or size optical disc?
If you can't use any conventional method to remove the
disc media, you may call ahead to an Apple Store with
Genius Bar and set an appointment to get some help.
That is, if you are in an area where the Apple Stores
have a Genius bar. In the US & Canada, this would
allow a free diagnostic; but not a 'repair' service...
Good luck & happy computing!
