The ability to create or change the disk label of fat/fat32/vfat file systems/partitions doesn’t come with Parted; yet is quite simple to achieve with Ubuntu Debian GNU/Linux :).
This comes in very handy when you have a number of fat devices (like USB, SD, etc) and want something more meaningful than just “disk” as its name.
Get mtools if you haven’t it already
sudo apt-get install mtools
Create a configuration file to avoid some error reporting
echo "mtools_skip_check=1" > ~/.mtoolsrc
Check where your disk is in the linux devices
Label your disk
mlabel -i /dev/sdb1 -s ::my_disc
…and there you have it.
Disconnect the device and reconnect it and the label will show when it is auto mounted.
