slot loading superdrive not receiving disc

Here's a note of me in an old thread:

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. Using the Terminal app:

Open the Terminal application in your Utilities folder. At the prompt enter or paste the following

drutil eject

or in case you have an external and internal disc drive:

drutil eject internal

drutil eject external

or

drutil eject -drive internal

drutil eject -drive external

If this fails then try this:

Boot the computer into single-user mode. At the prompt enter the same Terminal command as used above.

To restart the computer enter "reboot" at the prompt without quotes.
