encrypting existing partitions/disks

[Ronnel P. Maglasang]

Hello,

Has anyone wrote a how-to or a guick guide on how
to encrypt an existing partition/disk using gbde?
I've tried to search in the net but i cudn't find
any. Is it possible to just move the existing data
on my disk, cleanup the disk and encrypt using gbde,
attach to the system, then move back the data to the now
encrypted disk.

Thanks,
- ronnel
