QuoteI managed to format the card in an old 5D. Recuva has found a 2GB block of uncorrupted data but wont show it as individual files. Stella Phoenix has found all the images (& displays previews) ...I just have to pay the $39...
[UPDATE]
Reinserted the CF card into the 5DmkII & now the controls are functional. Reformatted the card then put it in a PC cardreader. Ran Recuva software again & this time it retrieved all lost images.
Result.
