As I know that maybe caused by marvell controller driver problem. You can Google it you will know.
From the manual, there are 6 of intel STATII ports ( 0-5) and 2 of the GA SATATII ports (GSATA8/9). You can use the GA-SATA ports for the 2 x 1 TB WD Black (RAID 0). The rest SSD, HDD, DVD into the intel sata ports.
