There is something called "TrueCrypt" which is so good that it will 
encrypt drives and only reveal the full unencrypted drive with a 
specific password/phrase. Otherwise, it will just show an ordinary hard 
drive and won't even reveal size differences to a forensic examination. 
Trouble is ... while it is available for GNU/Linux, I am not sure 
whether it works for OBSD. I guess if you have installed Linux ports 
then it might, but I'd leave that to others more experienced than me to 
figure that one through.
