The best of the lot is ProSel 8 or 16 depending on which variety of Apple
II you have.  It has a utility to do this, and it has a heap more useful
stuff.  I know that it's freeware but not sure where to send you for it. 
It'll be around somewhere.  

BTW when bad blocks start appearing on floppy disks, it really is time to
copy the data to a new disk and bin the troublesome one.  The problem
generally indicates that the disk is nearing its use by date and will only
continue to show problems.  "Bad block outing" is really only for hard
disks or perhaps large removables such as Zip disks.
