Hi Rick, there probably is. Boot into some nini root environment and
type:

dd if=/dev/null of=/dev/sda [assuming THE drive is sda]

this will overwrite the intire disk with zero bytes (or was /dev/zero
the proper device for that??). Atlernetivly, /dev/random might be a good
source of rubbish data. ;-)

there is the bs= parameter as well (block size). You probably need to
experiment a bit with that, I tried to copy a 20GB disk via dd and it
was dead slow, but I used 8KB as bs. I'd now start with a value of 4-8
MB.

dd if=/dev/null of=/dev/sda bs=512 count=1 will overwrite the boot
sector and partition table; but that's DOS-logic, I do not know how much
of that applies to original HP-UX disks.
