When I run 'dd if=/dev/rwd0d of=/dev/rwd1d bs=64k
conv=noerror' on
NetBSD, the command reports 'dd: conv option disabled' and exits.
I suspect this is because you're using the shell-out option frokm the
installer. On the installer, most programs are very stripped down, to
make everything fit on two floppies.
In short, this is not "NetBSD's dd" but "NetBSD's installer's
dd".
What you need is a non-stripped-down dd binary, and you won't find that
on the installer. (If you are using the CD image, it's there, but not
in a very usable form - it's in the "base" binary set, and while it can
in principle be extracted from it, it's midly messy to do so.)
