Hi I have Windows XP Home Edition (don't think it matters but oh well) I have a 60 Gig WD HD installed and I just bought a New 120 GIG WD HD and I want to install it so that the computer reads both hard drives as one? is that RAID? and I know that my mother board supports it as i was told by the place that I bought the Motherboard from. It is a Gigabyte board with Onboard AC97 Audio. How do I Install?
