I recently bought a 32GB SD card for my 60D. I have it set to raw + jpg and when I inserted it for the first time it showed 898 shots available, which looked right because my 16GB cards hold approx. 450 shots on a new card with the same settings.
I've taken 114 shots so far and noticed that the available shots were 234.
When I examine the card on a computer the image files add up to 3.3GB but the properties window shows that the used space is 22.4GB, and I can't see any other files on the card, unless they're hidden
Should I just reformat the card?
