What are the specs of the card ? Brand, CF or SD, etc ... did you format it in the camera before using it ?
It's a SanDisk Ultra, 16GB, CF. I believe I formatted the camera before I used it, but I can't remember as it was a few months ago.. I bought it right after I bought the camera and it's been in there ever since with no issues, that's why I thought it was strange to randomly pop up and say that it's full.
