I've just finished building a new machine. Everything seems well enough connected. the only hard drive in it is a western digital 80GB SATA. I booted it, posted fine, and then went to a screen about raid arrays (there's only one disk - I don't want to use raid anyway) where it lists the drive. It then went on to the next screen (devices and irq's etc) and proceeded to boot from the XP CD. XP setup then detected my hardware setings, loaded up, and when I asked it to install, it claimed that there was no hard drive present. The reason I didn't post this in the windows OS forum was simply becuse I feel the same would happen for any other OS. Can anybody tell me what I'm missing, or what I've done wrong? Can sata drives not exist as stand alone drives or something?
