2. Unmount your USB drive using the following command:
sudo umount /dev/sdd
Where “sdd” is your media drive you had to remember at step 1.
3. Format the drive using the following commands:
a) Format to FAT:
sudo mkdosfs -n 'Label' -I /dev/sdd
You can also use the “-F 32” parameter to create a FAT32 partition.
b) Format to EXT3:
sudo mkfs.ext3 -n 'Label' -I /dev/sdd
Where Label is will be the name displayed for the USB media so you can set it to whatever you want; and sdd is your usb drive you had to remember at step 1.
If your are not friends with command line tools, you can use a GUI for this called Gnome Format.
