Yeah, most mobos do come with built in a hardware SATA mode onnit you can enable or disable in the bios. Now since you're using just 1 the SATA RAID functions won't matter for ya, but they are sweet if you have an extra HD kickin' around. Now, here's the downside to Hardware SATA for RAID (don't think it affects singles) is that if your mobo dies, you'll need to buy most likely the exact same mobo to be able to properly rebuild the RAID array. You can also do software RAID modes with windows, but I figure I'd be a bit slower since tha'd put a extra little (or big I'm not sure) load on the CPU.
So yeah, for a single HD, I don't think you really needed to do anything other than plug it in, but I could be wrong.. I'm sure some else more experienced in the ways of SATA HD's will post hea.
