Recuva changing Numbers

[bxy]

16Gig Kingston Compact Flash Fat 64

Card is full or was before everything disappeared, deleted, formatted, corrupted: unknown

Card only shows a file structure n one file.

when running Recuva, at about 16% it says 723 found

when Recuva finishes it says 348 found 0 ignored 14 Gigs

The files recovered are from 3 shoots ago, nothing from the 2 shoots since.

The files from 3 shoots ago were deleted, the 2 newer shoots recorded over them

The new pictures were there on the card, we reviewed them, n copied a few before they disappeared.

Recuva was run in Deep Scan, with everything checked, including 0 byte files...

If we knew exactly what Recuva was doing them we might be able to explain this. It may be a number of things, for instance during the scan counting all the files found both in the directory and in the deep scan (large number), and then discounting those in the deep scan which already exist in the directory (smaller number).

Maybe, that could be an explanation. However the first scan I did was not deep, and found nothing at all. Have since done 3 deep scans, all the same results as above. And still why is it bringing back the old stuff that was recorded over (the whole shoot in tact) and not a single picture from either of the newer shoots?
