Ejecting optical media

Sometimes the “Eject Button” to eject optical media like cd or dvd doesn’t work.

This can happen due to a bad media inserted or else.

How to get the damn thing out without opening the case? In the ol’ days – where cds and such used to rest on a mechanical slider – there was a small hole to insert a <bueroklammer>. That would open the tray. This doesn’t apply to iMacs or Macbooks:

  1. Reboot the mac.  When you hear the bootup chime press the moue button and keep it pressed until the cd / dvd is ejected.

You dont’t always want to do that – try solution #2

  1. Use command line: a) identifiy your optical drive, b) tell os x to eject the media

a) identifying the optical drive

volkers-imac:shopper mupfel$ sudo diskutil list
/dev/disk0
 #: TYPE NAME SIZE IDENTIFIER
 0: GUID_partition_scheme *1.0 TB disk0
 1: EFI EFI 209.7 MB disk0s1
 2: Apple_HFS Macintosh HD 999.3 GB disk0s2
 3: Apple_Boot Recovery HD 650.0 MB disk0s3
/dev/disk1
 #: TYPE NAME SIZE IDENTIFIER
 0: Apple_partition_scheme *4.1 GB disk1
 1: Apple_partition_map 127.0 KB disk1s1
 2: Apple_MDFW 98.6 MB disk1s2
 3: Apple_HFS MupfelPod 3.9 GB disk1s3
/dev/disk2
 #: TYPE NAME SIZE IDENTIFIER
 0: Apple_partition_scheme *4.4 GB disk2
 1: Apple_partition_map 32.3 KB disk2s1
 2: Apple_HFS Hueter des Lichts 4.4 GB disk2s2
/dev/disk4
 #: TYPE NAME SIZE IDENTIFIER
 0: Apple_partition_scheme *2.0 TB disk4
 1: Apple_partition_map 32.3 KB disk4s1
 2: Apple_HFSX Time Machine-Backups 2.0 TB disk4s2
volkers-imac:shopper mupfel$ sudo diskutil eject /dev/disk2
Disk /dev/disk2s2 ejected
volkers-imac:shopper mupfel$

In my case disk2 represents the optical drive. With your hardware and setup the result may be different.

A subsequent call of “sudo diskutil eject /dev/disk2” shall kick the disk out.

Remember you need the admin password because of the sudo call.

If this doesn’t work for you try the first approach with rebooting your machine
