HI Everyone, I got a small machine that is used as shared drive while working. It has a Win2K SP4 with the main disk connected on the motherboard sata, a second disk on motherboard sata as well. I wanted to connect a third Sata drive, but got no plug, so I got a PCI cars with two Sata plug and raid capable . I Plugged it in and the disk too, it's recognized in boot, but it will fail to start after the raid boot. If I take off the disk it boot in windows but the card is not installed and the driver is not valid.... I can't install it. I tried the one from the internet, it still says it's not valid.... Do I have to delete my sata controller to re install it with the new card? is there something else? PS: if I plug my main drive on the card, I would see the splash image of windows and then blue screen..I guess it's normal as it's not installes. Thanks for the help. Hal.
