USB's storage capacity reduced to 2 MB from 16 GB

I downloaded ubuntu-13.04-desktop-amd64.

On Ubuntu's web page, I saw a link for making a bootable USB drive option, then I downloaded Universal-USB-Installer-1.9.3.3 and I made my USB bootable.

When installing the OS an error was found and installing not completed. After that I formated my USB but my USB's storage capacity reduced to 2 MB from 16 GB. How can I recover my USB size and install ubuntu.


Since there is no working answer yet, I post this:

The problem is that the remaining space of your USB flash disk has become unallocated. To repair it, use diskpart (in windows):

  • Open command line (cmd) and type diskpart. Allow the windows to run it.

  • type list disk, and find the number of your USB flash disk.

  • type select disk X, and type the number of the USB disk instead of X.It should say that disk X is now selected.

  • type clean.

  • type create partition primary.

Now you should be able to use the flash disk as before. (You have to format it first)


first of all open disk management. click on removable disk or pen drive you choose. right click on it and see the total space (sum of allocated and unallocated space) if the size is less than total space then follow these step. open cmd (in administrator mode) type "diskpart" press enter type "list volume" press enter type "select volume 6"
{select the removable disk option such as 1,2,3} press enter
type "clean" press enter then exit cmd go to disk management. right click on removable disk(your pendrive volume) open new voulume then new partition wizard will start . then click next until it is finished. now see your pen drive capacity it is changed!!!!!!!
