I would try disconnecting the ssd if it's your main boot device. Use the 500 gb western digital and boot up; try connecting the ssd while windows is running and see if it is detected under "computer". If the hardrive symbol is solid, this means the ssd still has a chance of being recovered. If the symbol is empty, then most likely the ssd is bad; Anytime you update the ssd firmware, you lose all your files, and have to either clone the ssd off another drive or start over with a fresh windows install. I've had two fail, and received brand new ones under warranty (different brand). It takes about two weeks to get a replacement; my last one happened right after the Taiwan floods, so it took longer for the replacement to arrive. Good luck.
