I have a professional Lexar memory card that says that it's memory is half full but the camera says there are no files, as well as the computer saying the same thing. On the computer (WIN 7), The disk is visible, but when opened there is nothing in it. When properties is opened, it shows that memory is being used up.
Any tips on making the files visible? The compact flash card is not on "lock" and doesn't even have that option.
