I have not heard of this happening?? I was wondering, do you take yours out a lot?? I wondered if this wears them out?? by putting them into the reader and the printer and back into the camera??? just curious Tom, not accusing you or anything... LOL!!!  Sorry this happened, and after reading punaguy's disaster with his photos, what next???? I guess everything has a time limit or shelf life, you just don't think these cards will expire??    AKemi
