My SD memory 2GB Tevion card was working well and showing me my photo's in my camera (CanonIxus 850IS) I used a card reader to transfer the photos (750) to my PC.At no 565 the PC said it was unable to download anymore due to an error. When I tried again no photo's were availaable and nothing showed in the card reader. When I put the card back into the camera it said 'Memory card error' on ablack screen and nothing else. Please is it possible to recover my photo's? I have just returned from Nepal and would be very grateful if anyone could advise.
