Well I recently made the switch from IDE to SATA II While upgrading my system. The hardrive is a Western Digital 250 gig SATA II With NCQ The motherboard has 8 SATA sockets. there are 2 controllers according to the Manual onlly one of them supports SATA II. I have it connected to the right socket and this is what it says in device manangr http://img454.imageshack.us/my.php?image=device7hy.gif This is results of the Speed test http://img454.imageshack.us/my.php?image=tet5ae.gif Now in my Bios there are 2 SATA controllers which can be enabled or disabled. If I enable the 2nd controller and connect by Hardrive it wont boot . Using My uADVD with all bashrats driverpacks and enabling the 2nd controller and connectign the Dirve It doesnt find any hard disk..But while Booting it says something like Silicon 3114 controller then the name of my Hardrive...Sorry if this is confusing but im a bit of Noob with SATA/Raid ..So basiclly is the score to low and why cant I hook my dirve to the other SATA controller?
