Colin,
You can try this after a backup:

* RepairHeaderAndMemo.prg
* Parameters
*	tcDBF          : Full path and name of dbf file to repair
* Remarks :
*   Has CDX flag is cleared && New copy has no CDX
Lparameters tcDBF
Local handle, lnFileSize, lnReccount, lnHeaderSize, lnRecordSize, ;
  lnCalculatedReccount, llHasMemo
Set Step On
handle=fopen(tcDBF,12) && Opened readwrite
lnFileSize = fseek(handle,0,2) && Get file size
* Read header info
lnReccount   = ReadBytes(handle, 4,4)
lnHeaderSize = ReadBytes(handle, 8,2)
lnRecordSize = ReadBytes(handle,10,2)

lnCalculatedReccount = floor((lnFileSize-lnHeaderSize)/lnRecordSize)
If lnCalculatedReccount # lnReccount && If calculated # recorded fix it
  WriteBytes(handle, 4,4,lnCalculatedReccount)
Endif
WriteBytes(handle, 28,1,0) && Clear has CDX, has memo, isDBC flags
llHasMemo=file(forceext(tcDBF,'FPT'))
If llHasMemo
  RepairMemo(forceext(tcDBF,'FPT'))
  WriteBytes(handle, 28,1,0x02) && Set has memo flag
Endif
=fclose(handle)

Function RepairMemoHeader
Lparameters tcMemoFilename
Local handle, lnFileSize, lnNextBlockPointer, lnBlockSize, lnFirstBlock, lnCalculatedFileSize

handle=fopen(tcMemoFilename,12) && Opened readwrite
lnFileSize = fseek(handle,0,2) && Get file size
* Read header info
lnNextBlockPointer = ReadBytes(handle, 0,4,.T.) && Stored in left-to-right format
lnBlockSize        = ReadBytes(handle, 6,2,.T.) && Stored in left-to-right format

* Specific to me - no blocksize setting to something other than default 0x40
If lnBlockSize # 0x40
  WriteBytes(handle, 6,2,0x40,.T.)
  lnBlockSize=0x40
Endif
*

lnFirstBlock	   = ceiling(512/lnBlockSize) && Possible min lnNextblockpointer
lnCalculatedFileSize = lnNextBlockPointer*lnBlockSize

* Fix if needs repair
If !(lnFileSize >= 512 ;
    and lnNextBlockPointer >= lnFirstBlock ;
    and lnCalculatedFileSize >= lnFileSize) && Memo needs repair
  lnNextBlockPointer = max(lnNextBlockPointer, lnFirstBlock)
  lnFileSize = lnNextBlockPointer * lnBlockSize
  WriteBytes(handle, 0,4,lnNextBlockPointer,.T.) && Fix next block pointer
  =fchsize(handle, lnFileSize) && Fix filesize
Endif
Endwith
=fclose(handle)

Function ReadBytes
Lparameters tnHandle, tnPos, tnSize, tlLR
Local lcString, lnRetValue,ix
=fseek(tnHandle, tnPos,0) && Go to pos
lcString = fread(tnHandle, tnSize) && Read tnSize bytes
lnRetValue = 0
For ix=0 to tnSize-1  && Convert to a number
  lnRetValue = lnRetValue + asc(substr(lcString,ix+1)) * ;
    iif(tlLR,256^(tnSize-1-ix),256^ix)
Endfor
Return int(lnRetValue)

Function WriteBytes
Lparameters tnHandle, tnPos, tnSize, tnNumber, tlLR
Local lcString, lnLowDword, lnHighDword,ix
lcString=''
If tlLR
  For ix=tnSize-1 to 0 step -1
    lcString=lcString+chr(tnNumber/256^ix%256)
  Endfor
Else
  For ix=0 to tnSize-1
    lcString=lcString+chr(tnNumber/256^ix%256)
  Endfor
Endif
=fseek(tnHandle, tnPos,0) && Go to pos
Return fwrite(tnHandle,lcString)
