Wouldn't /dev/urandom or /dev/random on Linux systems work better? It's 
the kernel's built in random number generator. It'd fill the drive with 
random bits of data. You could loop it too... in fact, I think many of 
the pre-packaged *wipe* programs are mini Linux distros that do just this.

dd if=/dev/random of=/dev/your_hard_drive
