Why does my MicroSD card not work anymore and get very hot?

When installing and removing the Raspberry Pi board into and from most cases, you have to remember to remove the MicroSD card or else you will bend the card. Bending the card will cause damage or cracks in the card that result in failure and additionally short circuiting. You void all warranty from the card manufacturer when you do this since this is considered user error resulting mechanical damage!
Once you have a card in this state, do not continue to try to use it as you will cause damage to your board due to the short circuit. Our Active Cooling Media Center case designs around this problem by extending the slot area to prevent this type of user error from occurring. When getting a new MicroSD card, consider getting our case as well to prevent future occurrences of this problem.
