This doesn't work the way you want. dd will write starting from the front
of the disk. It will overwrite something that the system needs which then
causes a crash before the disk is wiped, thus leaving recoverable data on
the disk.
I suggest that if you really want something like this, you have to reboot to a Linux CD, and run something like this 'shred -fz /dev/hda'. That will wipe out all data on the box with 25 overwrites of random data, and then nicely lays down 0s to cover your tracks. Nothing is going to save you, when the feds are knocking at the door short of a full degaussing of the drive. I have heard that some intelligence agencies have effectively done this, so they can destroy information in an emergency.
