When I had unbootable disks under netbsd I found it useful to dd over
the first track of the disk and start again. For a while (and perhaps
still???) fdisk and friends didn't correctly initialize a disk that
looked like it might be being shared between two OS's.
I've only done this dd when rebuilding a disk from scratch
(eg. followed directly by fdisk/disklabel/newfs/tar) so I've never
tested a mode where it just clobbers the first 64 sectors and keeps
all the fdisk partition 1 data. I normally just nuke a megabyte or
(As an aside, I think the only netbsd I installed from an install disk
was 1.2. All the rest were clones (grafts ???) from that original
