Thanks for the suggestion. At this point I've tried so many different
things that I can't remember exactly which ones I tried and failed at.
I'm fairly sure this was one of the things that was failing though.
I finally blew away the first few megs on the disks with a:
dd if=/dev/zero of=/dev/rwd1d bs=1024k count=16
Without a valid fdisk/MBR label disklabel worked like a champ. I then
put the fdisk label back. I think the problem may have been that I
tried to tell fdisk that my first block was 63 (so as to not overwrite
the mbr) and I told disklabel that my first block was 1008 (the first
After attempting to boot from the new disk, it was painfully clear
that I needed to tell both fdisk and disklabel the same start sector.
