It appears you FAT has become corrupt. ONE way this can happen it to
remove the card while it is still being written to, or, in some cameras,
power the camera off before everything is written to the card. There is
also the possibility of the batteries becoming too weak to finish a SD
card update. Avoid any of these actions, and avoid formatting, or
deleting from the computer.
