I have just burned an .iso onto a usb drive, and i suspect something has gone wrong as it won't boot, so i want to wipe it and try again, but it won't let me remove files. When I use fdisk -l I get:
Disk /dev/sda: 119.2 GiB, 128035676160 bytes, 250069680 sectors

But under /dev/sdb there used to be a devices section like with /dev/sda, I'm assuming its to do with that. How do I get that back?
