I have had an Olympus digital camera for 3 or 4 years now, and my SmartMedia cards I bought with it have always worked fine. About 5 months ago I bought a new PC with a built in card reader and suddenly my two SmartMedia cards died on me. I bought a new one and after about three weeks it is now not functioning correctly. My camera shows 0 pictures available on the card and when I put it in the card reader it says "The disk is not formatted." It then gives me the option to format the disk, but when I try to do that it says the disk is write protected. Is it possible that my card reader is damaging the SmartMedia cards? How can I remove the write protection that is supposedly on my card, even though I have not write protected it?
