I installed a Samsung Spinrite SATA HD 250 GB in to my system. I have a Gigabyte GA-K8NS-Pro mobo w/nVidia Geforce 250 3 chip set. I used the F6 method to load the nVidia drivers. The Silicon Image and Gigabyte drivers were already installed. None of the controllers nor WinXP sees the disk. It' getting power. Suggestions?
