Well, to quote the man page:

     Badsect is used on a quiet file system in the following way: First mount
     the file system, and change to its root directory.  Make a directory BAD
     there.  Run badsect giving as argument the BAD directory followed by all
     the bad sectors you wish to add.

I don't think anyone has used badsect in quite a while (because
of exactly the problem quoted above).
