Most common problem(s) are:
(1) Connection is not good, try reseating the Sata data and power connector on the drive, and the data cable on the MB.
(2) Bad data cable, try a different cable. If you do not have a spare, swap it for the one on the DVD drive.
(3) Bad HDD - Try another HDD.
(4) Bios not set correcly, verify that it is set to AHCI
