Edward,

By default, the mke2fs partition formatting utility reserves a certain
percentage of total capacity -- the default is 5% -- for the root user.
This is most important for root (/) filesystems, and certain other
filesystems mounted to it. It's hardly important at all for external USB
hard drives. You can use the tune2fs utility to change the reserved
space to 0%:

# tune2fs -m 0 /dev/hda1

Remember, don't do this to your root filesystem.
