Have you tried a complete rebuild of both the table and the index? I have seen situation where both a table and it's index seems to be ok, and even a pack and/or a reindex did not fix it. To rebuild the table completely, you have to copy the file twice

lcSafety=SET('SAFETY')
SET SAFETY OFF
USE myTable EXCLUSIVE
COPY TO dummy WITH CDX
USE dummy
COPY TO myTable WITH CDX
ERASE dummy.*
IF lcSafety='ON' && I hate the macro &, so I never use it unless absolutely necessary
  SET SAFETY ON
ENDIF

NB! VFP8 and VFP9 have better error checking of your tables/indexes!
