I really can't figure this one out, so maybe someone has some ideas.
About a year and change ago, I went from a Canon 5D Mark IV to a canon R6 mark II. Things went fine at first, but then I recently noticed I am having a bunch of SD card problems. I was getting the "card cannot be accessed" error
But its' frustratingly weird how the error happens:
It only happens in slot 1.
It only happens on cards larger than 64 GB. My 64 GB cards work just fine. I have a couple of different kinds of 128 GB cards in terms of manufacturers and they all act the same way. Any card larger than 64GB doesn't work in slot 1.
So if I take a 128 GB card and put it in slot 1, it gives me the error. I put that same card in slot 2, and it seems to work fine.
If I put one of my 64GB cards into slot 1 it seems to work fine.
I've tried formatting the cards, regular and low level format, to no avail. I've tried formatting the cards on a computer. No luck there.
And it is just slot 1. Slot 2, the 128GB cards work normal. Slot 1, "card cannot be accessed". But 64 GB cards work in slot 1, no issues. (and of course Slot 2, the 64GB cards work normal)
I even toggled the write protection switch on the cards back and forth. No dice.
It's as if my R6 Mark II can't "handle" a 128GB card in Slot 1. But Slot 1 can handle 64 GB cards. And the 128 GB card works in Slot 2.
I downloaded the latest firmware in hopes that would help. No dice.
Ideas?
