My Nikon D40 will only recognize pictures it has taken on my Ultra II SanDisk card...yet my Nikon Coolpix will recognize all pics on that same card that had pics taken with the Coolpix as well as the D40. In another comparison, my D40 won't recognize pics on a memory card I had used solely in my Coolpix. Is this a malfunction of the D40? If so, I need to send it in for warranty work.
