Having recently been bitten by a failing SCSI disk which obviously
has been set to silently remap any bad blocks, I noticed that we
don't have any tool to change that behaviour in-tree. Shouldn't
here be some utilitiy to change mode page bits, format drives etc.,
something like Digital Unix' "scu"?

  So I'm committed to write such a thing -- has anybody pointers,
ideas, fragments that may be used as a starting point as not to
write everything from scratch?
