These are "lost sectors". There are three common possibilities: 1) a directory
entry was deleted without deallocating the sectors identified in the
associated file descriptor sector (may be intentional or accidental);
2) the disk has boot information or other "partition" information which
is marked as allocated so that OS9 does not overwrite it; 3) these are
media defects.

You can leave these alone since they don't threaten data integrity, or
you can do a file-by-file backup, reformat the hard drive, and restore
to eliminate all but the media defects.
