Examples of the identifier then are disk0, disk1, disk2, and so on. You may see entries like this:. In this example, there are two physical disks disk0 and disk1 , each containing additional partitions. Read across to find the identifier, and then use just the base name of the identifier in the diskutil eject command. The DVD that is stuck in the Mac shows up as disk1s3.

Once you have the optical drive's identifier in the example disk1, you're ready to use Terminal to eject the media from the specific drive. Remember to change the identifier in the above example to match the identifier you found using the diskutil list command. If the stuck media is in an external DVD drive, there is a good chance that it may have an emergency disk eject system. This simple system consists of a small hole usually located just below the DVD drive tray. To eject a stuck DVD, unfold a paperclip and insert the now straight clip into the ejection hole.
