The following will also work in this case, and be *much* quicker :-)
dd if=/dev/zero of=/dev/rwd1b bs=2m
dd if=/dev/zero of=/dev/rwd2b bs=2m
dd if=/dev/zero of=/dev/rwd3b bs=2m
(adjust 'bs' to taste :-) )

Hmm... How big are the components? Is this error repeatable? (just searching
for more clues...)

Nope. (I just tried the above command on my test box, and it completed just
fine... so this could be a bit entertaining to track down :-/ )
