just got info, he had just put a new one in and it was formated and ready to use he took the remainder of weding photo's and that wast all he did, he took the cards to snappy snaps and they discovered that the cards had no pic on them both cards were empty, they then tried to see if they were deleted but nothing was on them, it seems the cards had a fault but when he reformated them snappy snaps took some pics but the camera did not put them on to the card, so it seems the set-up on the camera was wrong. his own fault he should have checked that they were sent to the card not the camera's memory.
problem solved.
