Have you tried to see if it will post without a drive in? Sometimes the SATA addressing can get messed up (my fanciful attempt at an explanation), and if you move the drive to another plug on the MB AFTER posting with no drive connected. Anyway it worked for me once or twice for hdds on two different-gen mobos. Maybe it makes the bios reset, I dunno, I'm more of a trial-and-error type of fixer.
