I always make a point of checking my SD cards from time to time. It’s arguably the most important thing in your camera, if its corrupt, not saving or recording your pictures everything else is a waste of time. I have heard stories, I’m sure you all have the internet is full of them, of photographers snapping away quite happily with the camera appearing to be working fine only to find at the end of the day the card is blank. It’s a nightmare scenario, all that creativity and hard work for nothing.
I probably pop my SD cards in and out of the camera more than most, I never download from the camera, I always put the card into a card reader to transfer the pictures.I just think it’s quicker and it’s one less thing for your expensive camera to do.
As you can see from the picture above the last time I checked my cards I discovered I a problem. Some of the plastic in-between the contacts had come adrift, now I was lucky I discover it in time before I tried to use the card the camera . Not only would it probably not have saved the pictures but if one of those tiny slivers of plastic had come adrift in the camera it could have meant a pricey fix.
I have no idea how the card got damaged, I store them carefully in a hardened case designed just for SD cards, its a mystery.
Anyway before it happens to you check those cards!
