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
