I've been having problems getting my SATA drive to run as SATA on my MOBO (Abit IS7), so today I bought a Kingwin PCI SATA card. Wanted to try it to see if the SATA HD speeds up. Looking at the Kingwin instructions, I think they have to be in error. They say to plug in the card while the computer is powered up. I feel sure this is an error, but wanted to see if anyone else has the card and knows.
