The message sounds like a card error. When you first use a card, or when you want to clean it of existing images, it is important to do a format of the card IN THE CAMERA, not on a computer that may have some differences in the way some of the formatting works. If you get error messages about a card, do a low-level format of the card in the camera (it's an option) - you should not have to do that every time you format.
As mentioned avoid micro SD cards with adapters, they can be very problematic. Make sure your cards are not cheap copies of brand units - get your cards from a trustworthy source.
cheers, TREVOR
