I just tried to transfer an SD card contents of my Nikon JPGs and none of them transfered. The process proceeded normally until the images started to transfer and then each one was identified with a red exclamation mark, and when it was done nothing had transferred. There was no explanation of what the red Excaim Mark meant or notification that it was doen attempting to transfer - no erros msgs at all. Anybody care to explain this? I have recently loaded iOS 6.1 (and that alone could be the problem), and this is a version 2 iPad with (I think it's a two, I know it isn't the Retina display or the square edged version).
