Ever seen this? The camera is a Canon 80D. I have a 32MB SDcard that the camera can format (even low level) but still the camera reports the card is full. I put the card in the laptop, and removed all partitions, recreated a FAT16 partition and formatted it, using two different programs. Still the card says it is full.

I know, just throw it away and get a new one but it is a puzzle I wish I can solve.
