At the end of that article:
http://headworx.slupik.com/2008/02/fde-full-disk-encryption-hard-drive.html
there are three useful links which maybe will clarify how FDE works.

from the last link:

"In short, it is a security solution that fully encrypts your entire
Hard Disk Drive (HDD), including the Operating System etc. It is one
of the "most transparent" encryption products you can get for your
computer. Once installed you just have to authenticate once before the
boot time, and if successful the HDD is unlocked and behaves like any
other HDD. You don't have to worry about what files to encrypt and
what not to encrypt. With FDE everything is encrypted. It is for the
same reason that the US Government is currently conducting a
competition of various FDE solutions to select and implement the best
one."

Cheers,
