GNOME Disk Utility
So far I’ve used
gparted to get info about partitions. But today I found another tool that is shipped with Ubuntu called GNOME Disk Utility. It is also good for getting info but it can do some extra stuff too: create images, mount/unmount partitions, etc.
You can launch it with the “
gnome-disks” command in the terminal. Or, just type “Disks” in the unity dash.
