It's easy to
format usb drives from terminal. But, you need to first find what's
your usf file system. To find this we can use df command.
df: report
file system disk space usage
Also, to be able
to format the usb, usb shouldn't be mount, if it is we are going to
unmount it.
Now, just to be
clear I am going to format my own usb step by step, at required steps
I will give the terminal screenshots.
