[kubuntu] Rename FAT label

The Kubuntu Jaunty did not allow me to change the USB diskdrive label. This I found was because it is FAT32 formated. Why would I want to change the label and maintain it as FAT32 format?

  1. If someone finds my disk and would care to return it, they can mount it and find my phone num ber as the label.
  2. The FAT32 allows me to plug the USB diskdrive to MS Windows and Linux operating system interchangeably.
  3. I backup to this disk for both operating system.
Here are steps to change the label name.

Step 1: Install mtools if not already done.

$ sudo apt-get install mtools

Step 2: Identify the USB diskdrive (or partition) to be formatted.
Plug in the USB diskdrive. Then identify the USB device in a terminal, type:

$ tail /var/log.messages

I found mine as /dev/sdb1

Step 3: Rename the label with 11 characters maximum

$ sudo mlabel -i /dev/sdb1 ::0161234567

Test the results by unplugging the device, then plug back in to see the difference. Thank to the reference at website.
