If the table is not a level 7 table you know the structure, it
shouldn't be too difficult. Just open it in a hex editor and fix it.
The structure of the header can be found in QFORMT.FAQ at

Hi Gary,

That file does not seem to exist.  Any other ideas ?

Jeff - Gary's suggestion to fix it manually with a hex editor is 
effective, instructive and builds your confidence in your ability to deal 
with such problems.  Just remember to make good backups before cranking 
up the hex editor.

You may feel more comfortable using a program designed to deal with such 
things.  dSalvage is about the best there is -- although it doesn't do 
Level 7 DBFs.  It should handle messed up headers OK, either directly or 
with some input from you.  It's a valuable addition to any developer's 
tool kit.  Last I heard it costs about $200.  For more information, see:

  http://www.hallogram.com/dsalvge/index.html 

There is a good pair of free DBF corruption fixers available, DBFCLEAN 
and DBTCHECK.  Both can be downloaded, complete with docs, as self- 
extracting files DBFCLN.EXE and DBTCHK.EXE from Gary White's site:

  http://www.AppTools.com/dbase

While there, pick up QCRPT.FAQ, which covers corruption causes and 
prevention in useful detail.

DBFCLEAN and DBTCHECK are also available on the borland.com web site at: 
  
  www.borland.com/devsupport/VdBASE/db_util.html

Whatever program you use, the best fix of a corrupt header is sometimes 
to create a new DBF with the required structure, then overlay the header 
of the new file onto the old one.

Many of us could probably manage to do this for you, ... but it's usually 
quick and easy enough to do yourself with the right tools.  It's 
something you really want to be able do yourself whenever it might be 
needed.
