You have my deepest sympathy. On my first 'serious' digital camera I omitted to format the card and had similar problems. Most pics were there, but the very best ones were lost. The really close-up pic of a cormorant which surfaced right in front of me could be seen on the camera but could not be transferred to my laptop. Same for a diving gull in close-up screaming at me with claws extended and beak wide open. Awwwww!
