Does this throw any light on the card requirements?

Is a UHS-II card a "Type II card" which the manual says "cannot be
used"?

Yup!

I don't think so. UHS cards are much faster than earlier cards with
"Class" ratings. And "Type 2" refers only to CF cards.

So now we know, the problem was, Peter was using a card which the D800
couldn't support. This time he actually had too much card for the camera.

There is nothing wrong with the card, and he should be able to use it in his
D500. That will handle UHS-II cards.

UHS2 is backwards compatible with UHS1, but there can be issues in
card readers that aren't set up for 2, just like Peter was told. I
still wouldn't be surprised if the problem arose from multiple
exposures, and some possibility that the backward compatibility
induced problems. There are more contacts on UHS2 cards, and contact
placement in the camera might be an issue. If I were Peter, I might
stick with UHS1.
