I have a mid 12 13" pro, which I upgraded to 16 gb of ram and 2 500gb Hard drives. Recently I replaced one of 500gb drives with a 1TB drive and now it appears it may have crashed. I am hopeful someone may have some better news. When I boot in disk recovery to check the drive, here is what I see. If the drive has failed, is it at least possible to recover data from it, or is it just toast. I have not backed this drive up. If your curious the 500gb you see works fine and checks out with verify disk. I appreciate any feedback in advance.
