Try formatting them with your digital camera before you use them. Sometimes you may not be able to view with your digital, but a card reader will show them. If you think you have photos on the card anddon't want to lose them, try taking them to a Walgreens (or other drug store) and plug your card into their machine if you don't have a card reader.
