so basically i would "dd if=/dev/four of=/dev/sd?", or am i missing 
something? I might try the wipedisk software I've got, I think it's 
DBAN, there maybe a random option there that might be faster than 
if=/dev/urandom. I'll try it on the 500GB I pulled as I'll be combining 
that one with another 500GB LUKS/LVM drive.
