That's not correct, -z adds a zero pass after the 10 normal passes of built-in data patterns (there are 25 total). Which is good! urpwnd is right, 10 zero passes is barely better than one. To undo 10 zero passes would be the same as undoing one - subtract out the average data, which is completely uniform.

This would've been done to destroy data dd if=/dev/zero of=/dev/<replace this disk you want to destroy>
