Try booting from the Recovery HD:Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the arrow button below the icon.Select Disk Utility from the list and click on the Continue button. See if this lets you erase the drive.

to Disk erase failed. Couldn't unmount disk, then you may have to force an unmount through the terminal. Launch up http://technology.siprep.org/fix-for-disk-erase-failed-couldnt-unmount-disk/ Terminal.app (through /Applications/Utilities or through a Spotlight search). Then paste in the command: diskutil list to list out the different disks. You should see some disks appear like /dev/disk0, /dev/disk1, /dev/disk2. http://forum.imgburn.com/index.php?/topic/17037-error-erasing-disc/ Find the one you want to force unmount. For this example, let's say it's /dev/disk2. Run a command similar to this one sudo diskutil unmountDisk force /dev/disk2 If you're prompted for a disk erase password, enter it (yes, your account does need to have administrative privileges). You should not physically unplug the drive. You should now be able to erase the drive.
