You'll find more pertinent information in either the Administrator's
Guide, or in the Owner/Operator's Manual, and in the manual page for
hdefix(1m) [I think that's the correct spelling -- check the Permuted
Index or the "See Also" section of the hdelogger(1m) manual page].
Hdefix is the command you must run to permanently mark the given
sectors as bad.

(How can anyone say the 3B2 documentation doesn't give sufficient
information.  I've never seen so many manuals for a system!)

/etc/fmthard does not format disks, but rather only lays down a new
VTOC (Volume Table Of Contents).

To re-format a drive you need either the devtools disk, or the (newer)
idtools diskette.
