Trying to format a USB to FAT16 on Moblin or Ubuntu NBR

Why? FAT16 apparently needed while following this tutorial on creating a Parted Magic LiveUSB http://partedmagic.com/documentation/130-creating-the-liveusb.html

pendrivelinux.com/restoring-your-usb-key-partition and simplehelp.net/2009/04/24/… are the best i've found so far - but ubuntu doesn't have unmount – ina Aug 10 '10 at 8:15

sudo mkfs.vfat -F 16 <device>

on moblin: i get command not found. fdisk also command not found. – ina Aug 10 '10 at 5:59
    
on ubuntu 10 nbr i can't easily reference the device - is there a way to list where the usb is? – ina Aug 10 '10 at 7:51
    
"unable to open /dev/sdb" – ina Aug 10 '10 at 8:16
    
You should probably be formatting the partition, the the whole thing. After plugging in your USB device and waiting for it to settle, unmount it and then type dmesg. The last lines should show you the partition (ie /dev/sdb1) which was mounted. Format that as root. – Borealid Aug 10 '10 at 13:34

It looks like Ubuntu NBR and Moblin don't have unmount commands with their visual Mac-like interfaces...

  1. Ubuntu Netbook Remiz 10 - System > Admin > Disk Utility. Click unmount. Click Format Drive.
  2. do the mkfs suggested above.
  3. sudo mkdosfs -I /dev/sdb
