I'm trying to add a Seagate 250 gig drive to my p4p800 e deluxe. I already have two 36 gig raptors in raid 0 ( Yea I know this isn't the smartest thing to do). The raptors are on the intel chip. I am pretty sure I have the bios set up properly. The drive shows up in the bios and during the start up. It just won't show up in windows. I've tried to uninstall/reinstall the "WinXP Promise Fast Trak 378 Controller" ( There is an exclamation point next to this device in the "device manager" and the error is "This device cannot start. (Code 10)".and keep get a screen that reads "A problem occured during hardware installation, Your new hardware might not work properly". If I unplug the raptors the I have been able to install windows on the new drive. When I plug the raptors in, the new drive will not show up in windows again. I am really getting frustrated with this. Can someone help?
