AcuCorp Vision Broken File

I have a couple of files (600,000 & 900,000) records that are broken.  All
of our efforts using Vutil will only recover about 1/2 of the records.

Does anyone have any suggestions about a tool that might help in the
recovery of as much data as possible.  These are history files, so
anything that is recoverable is better than nothing.

Never mind,  I just found out that the end of these files are garbage (i.e
zeros), not recoverable data.
