I haven't ever tried this, and I'm not going to since I don't have any disks that I *want* to lose the data. :)
dd if=/dev/urandom of=/dev/ad0s1a
should do the trick. Of course substitute the 'of' attribute with the mount point of your choice.
I'm not entirely sure what will happen when the disk fills up. You may need to use the 'bs' flag. man dd for the syntax.
For an added dose of paranoia, run this command a few times.
Good luck with the feds! :)
