1. The first thing to do is try another SATA cable.
2 . The second thing to do is update the motherboard's BIOS if #1 does not fix the problem; go to the manufacturer's home page to check and for instructions.
3. It is possible that the hard drive is defective. Stick it in another PC for a couple of days to find out if the HDD "disappears" in the other PC. If the HDD does disappear then request an RMA for a replacement.
4. If #1 - #3 does not resolve you issue, then it is most likely a motherboard issue. Get an RMA from the place you bought it at so that you can exchange for another one.
