---------------------------------

$ dd if=/dev/zero of=/dev/hda count=1 bs=512

Formatting Flash Drives With An Ext3 Partition
----------------------------------------------

Start by running fdisk at the prompt, and delete any existing partition.
Once the problem partitions are gone, use cfdisk to create a new
partition table. (Or use fdisk---you crazy freak.)

$ mkfs.ext3 -m 0 /path/to/device

This will format the drive as ext3 and NOT reserve blocks for privileged
users.

Finally, you will want to run the following to disable forced file
system checking every 'x' mounts:

$ tune2fs -i 0 /path/to/device
