Indeed it seems many disk vendors disable bad-block remapping by default
unfortunately.  I've only found it enabled by default on newer IBM and
Seagate drives (but perhaps it is still not on by default on drives
classified as "AV" models).

Unfortunately scsictl cannot yet re-enable automatic read and write
reallocation.  The old scsi(8) command from FreeBSD (you can find it in
the Attic directories of their repository) can be compiled on NetBSD,
and it can do all kinds of nifty SCSI mode-page manipulation.
