Huh, they are rather low-level.  I wonder how you managed to ``correct''
them with NDD.  Probably NDD did only include them into the DOS bad
sector list?

You could also use the ``bad144'' bad sector replacement on BSD, but
if i were you, i would backup the entire disk, and see to hardware-
reformat it.  (I hope it's not a Quantum, they cannot be formatted at
all.)

Note that ``hardware-reformat'' is quite different from what DOS' format
program does; it requires a special utility that is usually available
from several disk manufacturers.

Of course, you could go SCSI :), where disk formatting is standardized.
Then you can use /sbin/scsiformat...
