In a question, why ? Woulden't writeing zero's over it work ? (or 1's if you prefure), the way I see it, you only need cryptografically secure numbers to slow down a hardware attack (ie "they" have the HD, don't put anything on floppies, or burn them after use ;)

And you seem paranoid to me, I like zeros, and it dosn't suck away all the entrpy in your pool ;)
