Do you have any numbers how many users have one disk and how many have
multiple disks? Security is a complicated thing and without proper OS
support it is nearly impossible for Joe User. In a multi disk setup it's
like having a $500 lock at the front door and leaving the back door
open. And it's a shame that security is always the first thing that goes
down the drain.
