no. I didn't stomp while running the verify. I stomped and then ran it. In 
fact I did it a couple times, as at first I wasn't stomping on much data, 
later I zeroed out a 40 meg chunk, about 40 meg into the partition.

(hhmm, sorry, looks like it was 4 Meg into the partion, .bash_history has 

dd if=/dev/zero of=/dev/vg1/nineteen-sys seek=1000 bs=4096 count=10240

I can redo it tomorrow if you like.
