|Do you have BOTH the red Data cable AND a power cable connected?|
I see that board only has SATA III connectors. If your drives are SATA I that may be an issue.
Also, there are some ports for RAID (blue) and 2 for straight drives (white). You need to set the BIOS to AHCI, settings or, NCQ, if your drives support it for hard drives.
I recommend that you connect the hard drives to the Blue ports. Use the White ports for your CD drive/s. See the link below for specs on that board.
