  1. I'm wanting to upgrade to a better mainboard. I don't know much about SATA, but I've been using a SATA I hard drive very successfully through a pci controller card.

    My question: If I get a new motherboard with SATA II headers, will it readily accept my SATA I hard drive? I can see how the reverse might not work, that is, not being able to connect a SATA II hard drive in a SATA I header, but maybe I'm wrong on that...?

    Yes, sata 3gb/s ports(commonly called sata II), are designed to be backward compatible. I'm using a sata I hd on my sata 3gb/s port on my chaintech vnf4/ultra, so yeah, it works.

    actually, you can even use most SATA-II drives on SATA-I boards. I have a Maxtor drive that even has a jumper to force SATA-I compatibility if your SATA-I board for some reason still won't recognize it (ie. some older VIA chipsets)
