What are the capacities (in gb) of the old and new CF cards?

Did the problem first occur while shooting or after transferring photos to a computer?

After transfering
Expert:  Russell A. replied 11 months ago.

Check inside the memory card slot with a flashlight and a magnifier (if necessary) to see if any pins are bent. A missing pin will keep the camera from reading the card. Please let me know what you find.
