I read this on the Fuji site: It sounds as though the pictures are lost. Maybe some else, may be able to suggest a remedy that will help.
Why am I getting a 'Card error message'?
The smart media card may have been damaged. This problem occurs when the card is removed before the card reader has finished or dismounted.
Go to 'my computer' and right click onto the removable disk icon and then click on eject prior to removing the card. If this procedure is not followed, the card can get spiked and it damages the CIS - which renders the card unusable. Try formatting the card in the camera, if this still fails then the card is ruined and can no longer be used.
