The memory card of our camera (Nikon digital) should take 2000 photos. In the process of uploading about 550 photos onto the pc, we appear to have lost 50 or more. They're no longer on the camera and aren't showing up on the pc. Bizarrely, just one of the lost 50 photos is on the camera mixed in with the others but hasn't transferred onto the pc.
Is there any chance of finding the lost photos on the memory card?
