I have tried
gnome-disk-utility and it has failed. Yet again I have deleted the launcher for, 'Disks' which is gnome disk utility and now I can't see how I can open it. I am running 12.10.
The auto-suggestion from package management sometimes helps out when you make a typo ( :) )
No command 'gnome-diskw' found, did you mean: Command 'gnome-disks' from package 'gnome-disk-utility' (main) gnome-diskw: command not found
