I tried to unmount disk0 by typing: diskutil unmountDisk force disk0 In the picture above, for some reason, there were 15 different disks. I can't guarantee this will work for you, but this is what worked for me: I finally got it working, in case someone else runs into this issue, these are the steps I took. This is going to be a tough one, so if anyone could help me out, I would appreciate it so much. I need to get this hd unmounted so I can erase the hard drive, and I've run out of options. "Forced unmount of disk0 failed: at least one volume could not be unmounted." I then typed: diskutil unmountDisk force disk0 Followed by error: I've went into Terminal, and typed: diskutil list When I try to expand the partition to fill in that extra space, and click "Apply", I get the error: When I go into the Partition tab, I have one partition, and it's 275.44GB out of my available 320.07.

When I click on the Mac HD (which is named "320.07 GB Hitachi HTS545032B9SA02 Media"), and then went to the Erase tab, and clicked "Erase." and I get the error: I have the original Mac installation disk in the computer, restarted the computer, and got into the Disk Utility by holding command + R, while it was restarting. I'm having trouble erasing the Mac hard drive though. I've been having issues with my computer constantly restarting after updating to Yosemite, so I'm trying to restore my computer back to factory settings (snow leopard) and going from there.
