Actually, by using /dev/urandom, it won't wait for new random data. You're probably thinking of /dev/random which will wait until it gets new random data. /dev/urandom uses the random data that is available as a seed to initialize a random number generator. /dev/random gets *all* of it's random data from random events like keypresses, mouse clicks/moves, or network packet arrival. Still, BCwipe probably has a better interface, but if you'd still like to use dd, don't worry about blocksize. dd will figure everything out for you fill the entire disk.
