First of all, try any Undelete program such as Copy II+ (and possibly
Pro-Sel).  These are designed to do all the grunt work of fixing the
directory entry and recovering deleted files.

If that fails, go get yourself a copy of Inside ProDOS which is an
excellent manual for anyone doing byte twiddling on ProDOS disks.  It
gives you all the information on directory contents, file types,
finding 'lost' files, and a bunch o' other nifty information.

Good luck.
