When using Ubuntu, there are many different ways to manage your disks, both your hard drives and your removable drives. However, there is one centralized location where you can manage all the drives connected to your computer. Using the Disks utility, you can format, eject, and view the used space on all your drives from one application.
To launch the Disks utility, summon the Dash by hitting the SUPER key or click on the Dash icon at the top of the Launcher. Once the Dash appears, type “disks” into the search field, and then click on the Disks icon when it appears. Ubuntu will then launch the Disks utility.
The Disks utility has two panes in its window. The left-hand pane lists all the drives, both internal and removable, connected to your computer. The right-hand pane displays details about whichever drive is currently selected in the right-hand pane.
The right-hand pane will show the type of drive, and the volumes upon the drive. It will also display the serial number, the total size of the disk, and the amount of free space upon the drive. Additionally, it will list the serial number and the health status – if Ubuntu detects problems with the disk, it will display them here.
In the upper right-hand corner of the right-hand pane, you will see a gear button. Click on the button, and the Disks utility will list the available actions for that drive. Usually they include ejecting the drive, formatting the drive, and creating a disk image based upon the contents of the drive. Finally, if the drive is removable, there will be an Eject button next to the gear button. Clicking on the Eject button will unmount the drive so you can safely remove it from your computer.
