My Canon A700 is displaying 'Card Locked!' on start-up, and no further progress. However, the card is not locked, and works in my Lumix TZ8. Putting the card in my PC, a folder has appeared named EOSMISC, containing 3 objects, M0116.CTG, M0117.CTG and M0165.CTG. I have no idea what these are. Although a few years old, this camera is still in use, and any advice on solving this problem would be greatly appreciated, thank you.
