Pendrive is a type of external device which helps us to stored data,files. But sometimes when we are using in our system it shows to format it before it can be used. Sometimes we can see that our pendrive is of 8gb but it is showing only 1gb and when you format it, it still shows only 1gb.

There is small tutorials how to fix that issue, below are the necessary steps.

a) Go to start meny and in search command prompt and press enter
When command prompt is open simply type "disk part" and then enter
c) After that type"list disk" in command prompt and press enter
d) Now again type "select disk" and enter. After this option a selection will be given
e) Finally select it and type "clean all" and enter

Now you will see the drive which is showing 1gb it will now show 8gb.
