Actually, one of the main causes of adapter failure with micro-SD cards is heat.

Bob, I'm having the same issue, using a new 64GB Sandisk Extreme PRO SD card (not a micro/adapter combo). I got the card brand new with a new 70D, and it's worked just fine together up until today. This morning it happened twice at the end of two shoots. And now, it won't even let me shoot at all. Any ideas?
