Unrecognizable memory card

My 32 GB Class 10 MicroSD card suddenly stopped working in my Galaxy Note 2. My note 2 is showing an error " Memory card has blank storage, needs to be formatted". And after few minutes stopped detecting my memory card.  I tried to connect the card to my laptop with the adaptor provided, but still it’s not getting recognized. Can you guys please guide me what to do? 

you have a bad card. contact sandisk support for a replacement. 

what about the files in the card?

there are important videos and pictures in there.

how do you extract the files before replacing the card or formating it?
