Insert in your USB drive and immediately after in terminal type
<code>
dmesg | tail
</code>

You'll see some system messages caused by the insertion of the drive.\\
Look for the drive 'identifier' in square brackets like ''[sdb]''\\
Use this drive identifier in later commands.\\
**PS** You can also use "''sudo fdisk -l''" to identify a drive that mounts.

If the drive is mounted, you need to unmount with
<code>
sudo umount /dev/sdb
</code>

To format the drive as FAT
<code>
sudo mkdosfs -n 'Label' -I /dev/sdb
</code>
Use the "-F 32" parameter to create a FAT32 partition.

\\ 

In the rare case you need to do a EXT partition, use
<code>
sudo mkfs.ext3 -n 'Label' -I /dev/sdb
</code>
In this formatting, some reserved space is created that is really not needed on a thumb drive. You can remove this space with
<code>
sudo tune2fs -m 0 /dev/sdb1
</code>

\\ 

PS **Label** is the name you want the disk to show on mounting.
