  WP> don't need fdisk if you do only netbsd.

  WP> ...please remove mbr with...

Will my boot selector program survive that, or should I
re-install it before my next boot?

  WP> run disklabel -i wd0 and do only W once again

Thanks, I'll try that.

Hmm, I'm not sure how large the files are likely to be. I'll
give this some thought.  Thanks.
