I think I got the Gigabyte vs Gigabit label wrong, but the general
principle is the same.

For an example, compare your `df -H` to `df -H`

My DVD partition:

mythtv:/home/MythVideo  636G  551G   85G  87% /home/MythVideo

versus

mythtv:/home/MythVideo  682G   591G    92G  87% /home/MythVideo


I'm fairly sure it's the issue of this conversion couple with the
reserved root blocks that's making your space poof.
