I bought a gently-used 5D mark II a few weeks ago and I've been using it just fine with ML on a 32GB and 64GB CF card until a few days ago when it suddenly stopped working.
The camera will boot only without a CF card or with a 4GB card that the seller gave me. It won't boot with the 32 or the 64. I've tried uninstalling ML, formatting the card, disabling and enabling the boot flag on both, tried the LED and display diagnostic methods, and restarted the camera continuously while switching multiple batteries out.
The LED will blink when booted without the card, or with the 4GB, but won't blink with the 32 or the 64. As far as I can tell, the camera functions just fine when it boots, it just won't boot with the cards I actually need it to boot with.
Initially, I thought the issue was just a faulty card, so I had the 64GB replaced through Amazon. After trying out the replacement card today, it still did not function, and did not function after reformats.
What might be wrong here, and what should I do?
