Having problem unmounting your disk. Here is an alternative to restarting your computer to eject your unresponding disk.
Having problem unmounting your disk? Try using your Terminal application before restarting.
- Open the Terminal application.
- Then type ‘df’. This will display a list of all mounted disk items.
- Find the disk you want to eject.
- The disk I was looking to unmount displayed like this:
“/dev/disk1s1s2 208484 208484 0 100% /Volumes/Alex Model Pix”.
- Above you see first a Unix name “/dev/disk1s1s2” followed by the CD volume name “/Volumes/Alex Model Pix”.
- Now type “hdiutil eject FullUnixName” to eject it.
- Example: “hdiutil eject /dev/disk1s1s2”.
That’s it. If this does not work. Just restart or poke a pin inside the hidden eject hole by the disk tray if there is one.
