  Won't (for example) `dd if=3D/dev/rsd0a of=3D/dev/rsd0a bs=3D32k conv=3Dn=
otrunc`
  do just that?  You probably don't need the `conv=3Dnotrunc' when using the
  raw partition.

I suppose it would, but that seems scary.   I'd like to see something
that retries the reads, perhaps many times, falling back to single
sectors from blocks, and only rewrites areas that read ok, saving a
log of non-rewritten sectors.  I've just never gotten around to
writing this....
