maybe you can try to use sata dvd drive and connect your HDD and DVD sata connectors cable to sata5 or sata6 conectors in your biostar motherboard. i've try to connect my HDD to sata1 to sata4 connectors and it get "still waiting to root device". my friend told me its caused by jmicron chip compatible issue.
