Bought this SATA hard disk(250GB) a few weeks ago and fixed my computer. I am using Gigabyte K8VT800M as my mother board. I see a exclamation mark on on the icon of "VIA SATA RAID CONTROLLER" in my device manager. It is not a question mark behind, so I guess the drivers are installed. The hard disk is running. However, I can't seem to detect the SATA hard disk(Can't find it in disk management), is it because my motherboard doesn't support SATA II? It says here: http://www.gigabyte.com.tw/Support/Motherboard/FAQ_Model.aspx?FAQID=1724&ProductID=1711&ClassValue= If I have to change the jumpers settings, how do I do it?
