Which is the best Canon Eos 70D or canon 5d mark iii?

It's hopeless then. I use Recuva but I don't see any advantage over those you already tried. Recovery is not always successful.

Not formatting doesn't mean you'll get everything back. Corrupted files, even if not formatted are gone forever. You've learned this lesson the hard way.

Do not keep pictures in the card for long term storage. Burn to CDs/DVDs or copy to external hard drives. Plurals intended.

Keep each copy in a different safe place. That's the only way to be sure.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
