It sounds like you have a defective card.

Have you tried using an adapter or hook it up to a computer instead?

IIRC, flash memory shouldn't need to be formatted. i've never formatted a card i've gotten.

It sounds like an issue I had not too long ago with my 16GB MicroSD card.

To make a long story short, I ended up returning it for another one that worked right out of the box, no formatting needed.
