disk data protection

[Dimitri Georganas <dg_(_at_)_mitc_(_dot_)_net>]

Hello list,

Is there a way to protect a disk with sensitive data in a way that it 
will only work and will only be readable if installed on i.e. System A? 
So if the disk is stolen and installed in a System B, it shouldn't boot 
and if mounted like mount /dev/wd1a /mnt/ the contents shouldn't be 
readable.
