Possible issues and resolutions If you have multiple memory cards, initialize another memory card and take some test shots. If images can be played back normally, the card that shows the error message may be malfunctioning. Try reformatting the faulty memory card to solve the issue.
When the card is formatted, all images and data in the card will be erased. Even protected images will be erased, so make sure there is nothing you need to keep. If necessary, transfer the images and data to a computer, etc., before formatting the card.
