I formatted my card so it showed empty. I took photos for two weeks. The next day after taking a few the card said FULL. I scrolled back. Only the new photos plus some very old images were there.
I removed the card to download to my iPad. The card reverted and showed previous images, not ones taken that day. It performed as normal until another occasion when the same thing happened.
How can the card have this double life and how can I get the few images off?
