That is a clever bit of script. I wasn’t sure if it would work on my current macbook pro as i noticed this post was over a year old but it works great still. Thanks

Brilliant! I have been looking for an easy way to mount my external Firewire drive only when needed, and this saves me a tedious trip to Disk Utility every time I need the disk available.

Thanks very much!

Thanks for the post! After I modified it, it seems to be working great and good.This script solves all these problems!
Thanks for this script, its just what I am looking for. It works with my external USB disk perfectly. Now I can mount it without having to turn the switch on and off again, having to enter terminal lines, or fudge around in Disk Utility.

Have you managed to unmount the drive using Terminal? Why do you think its a cable issue of all sudden?

Do you think that this could be a problem with the Hard drive cable inside my computer? I was able to boot with my external drive as an internal on my sisters mac.

You could try this in Terminal:

diskutil unmountDisk force ...

Put your internal HDD name at the ellipsis, e.g.

diskutil unmountDisk force "Macintosh HD"

Make sure your current external drive is not called the same as your internal drive though. You may also use a unix device path to it. (E.g. /dev/disk1). To find it, in Terminal, use

diskutil list

I am trying to partition my new internal hard disk so that I can install OS X on it. I am currently running my mac on an external drive. When I try to partition my drive, it get an error: “Could not unmount disk.” Can this script help me with my problem? Please help me. :’(

What a stupid mistake. Thank you Lewis, I updated the above script.

Fantastic script! I have a really fast drive that I use for music but it’s way too loud and keeps spinning up/down. This script solves all these problems!
