The first thing you need to do is a backup using something that backs the
volume on a block by block method, like Prosel's backup.  It would be
preferable to also backup those blocks that are marked as unused in the
bitmap.  The next thing you will need is a copy of the Prodos Technical
Reference manual and/or Beneath Apple Prodos so you can figure out the
directory and subdirectory file layouts.  Then you just go through the files
(using block warden's follow command, looking to see if the information in the
file is in the right place and either restore or makeup the information that
should go there.  You basically rebuild the directory by hand.  Subdirectories
also show the location they are stored in their parent directory, so you will
have to make sure the pointers for a directory point to the correct place in
their parent directory.  Which directory was it that crashed?  A normal
directory or one that you created?  Did it have a bunch of files in it?  Are
the lost files really required?  If the files can be deleted, you can use a
documented method of removing entries from directories, then let Mr Fixit fix
the bit map to show the correct blocks used.  This will of course require all
the other files to be in good shape, or it may make a bad situation worse?

Above all else, extreme care and patience will be required.

If you would like help, some of us here do disk recoveries for varying fees
ranging from free to a few hundred dollars depending on the kind of day we'e
had.  Fortunatly, we usually have pretty good days.
