I'll be there.  Grab me if you get a chance and we'll take it apart.

I wouldn't use /dev/random for that. It blocks when it runs out of 
entropy which is very soon in that case. It could take some days to get 
enough data from there. If you insist on pseudo-random data, try 
/dev/urandom. It might not guarantee as much randomness but at least it 
doesn't block.
BTW: yes|dd of=/dev/hdX
