|Another idea if the above does not work. Try to format the card, if it is removeable, in a camera.|
If you get it to format you can place it in a camera and take pictures until the card is filled. You need not take anything special. Just snap off anything until the card is filled.
After it is filled place it into the jump and view all of the photos as a batch, as thumbnails. Look for photos that are not complete. Either the top or bottom or anywhere in between where the image is missing. On my camera this usually is a horizonital band. If you find any pictures where the image is not complete chances are the card is damaged. You can still use it for pictures but one of your pictures will not be good 'on the roll'. You just don't know which one.
The damaged 'frame' shows the card is not pure or consistent. That is why it might not work for all applications. It's like driving on a road and the bridge it out. Road on both sides but no way to cross.
Good luck and a good question you posted!
