Kingston datatraveler ext3 format
I have got a USB pen called Kingston datatraveler with 2 GB of data and I decided to use it as a backup media for my most important files. But first i needed to format it which was very easy actually. My usb pen was on sdf
sudo mkfs.ext3 /dev/sdf
Put a label on it:
sudo e2label /dev/sdf usbpen
You should now be able to see it under places -> Removable media -> USB pen. Or /media/usbpen (gnome desktop)
