Unmount i terminalen

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.

1. Open the Terminal application.
2. Then type ‘df’. This will display a list of all mounted disk items.
3. Find the disk you want to eject.
4. The disk I was looking to unmount displayed like this:
“/dev/disk1s1s2 208484 208484 0 100% /Volumes/Alex Model Pix”.
5. Above you see first a Unix name “/dev/disk1s1s2″ followed by the CD volume name “/Volumes/Alex Model Pix”.
6. Now type “hdiutil eject FullUnixName” to eject it.
7. 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.
