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.

Cheers,
Tanner
