commands used:

to find out your device location/letter:
sudo fdisk -l

example: /dev/sdX

to format to fat filesystem:
sudo mkfs.fat -n "Gotbletu" -I /dev/sdX
note: -I = that is a capital i not l

for ext2:
sudo mkfs.ext2 -L "Gotbletu" /dev/sdX

NAME
mkfs - build a Linux filesystem

DESCRIPTION
mkfs is used to build a Linux filesystem on a device, usually a hard disk partition. The device argument is either the device name (e.g. /dev/hda1,
/dev/sdb2), or a regular file that shall contain the filesystem. The size argument is the number of blocks to be used for the filesystem.

The exit code returned by mkfs is 0 on success and 1 on failure.

In actuality, mkfs is simply a front-end for the various filesystem builders (mkfs.fstype) available under Linux. The filesystem-specific builder is
searched for in a number of directories, like perhaps /sbin, /sbin/fs, /sbin/fs.d, /etc/fs, /etc (the precise list is defined at compile time but at least
contains /sbin and /sbin/fs), and finally in the directories listed in the PATH environment variable. Please see the filesystem-specific builder manual
pages for further details.
