I switched it to another SATA port, and it showed up, but then "Explorer stopped responding. I restarted andthen it wasn't there again. I hear and feel it running, it's only a couple months old.........
UPDATE 10 minutes later I just cleared the CMOS, and now it's back.
Update 20 minutes: I see all of my folders, but when I open them, it says' it's empty
