Filling with random numbers (ie. using /dev/random instead of
/dev/zero) would also work - but there's of course the slim
chance, that the random numbers make a real partition table.

It's slim, but it exists (but I don't know if it isn't much
more likely to win 10times in a row the grand prize in a 
lottery *G*).

Yes, it will, as the partition table is in the first 512bytes 
of the HD. At least the "primary" partition table is to be
found there - if you use an extended partition with logical
partitions, those logical partitions will have "links" to the
next logical partition.

But as the partition table doesn't exist anymore, the logical
partitions cannot be found (easily).
