For some reason my memory card has lost all of the data on it - probably about 150+ precious photographs. I thought the camera was faulty, but now realise that it must have been the card. My husband has changed the card, and when we have tried to download photographs from the original it is showing 'no files'. I do not know if they have been accidentally deleted, or if something else has happened to erase the card.
What are my chances of being able to retrieve the photographs? If I attempt to do this myself, which is the best programme to use? Would I be better off taking it to a computer expert to try to retrieve the data?
