Thanks for sharing.
My SP Silicon Power USB is 8GB, but windows just recognizes it as 2.1MB only even I tried to format it several times. This problem is fixed for my case by following these steps:

Open up command prompt as administrator and , type the following, pressing Enter after each command:

diskpart

list disk

select disk x (where x is the number of your USB flash drive – use the capacity to work out which one it is)

attributes disk clear readonly

clean

create partition primary

Now I press Window + E, to open Explorer and then click on Computer, click on the USB disk, and Windows should ask to format the USB normally again.

We glad it helped, these new flash sticks are very fragile, so just be sure to always eject, and treat them like they made out of glass…if you do that you won’t have anymore problems.
