I changed my Ubuntu 12.04 to 13.04 and now I want to format my USB flash when I right-click on my USB icon on Launcher.

I can see only 4 options:

  1. Open
  3. Unlock from launcher
  4. Eject.

There is no format option. Thank You

Install gparted

sudo apt-get install gparted

Open it and in the right corner select volume you want. Be careful! /dev/sda is most likely your hard drive. Use the drop-down arrow to switch to the USB drive. If you have more than one USB drive mounted, be sure you are choosing the correct one. Additional devices will be /dev/sdb, /dev/sdc, and so on.

Right click on the USB flash partition and you'll see format option. If it is grayed out, you need to unmount the USB drive first.
