I'm not really getting what you are saying but if you say what I think you have to reinstall Windows on the raptor disk. First be sure that your motherboard supports S-ATA disks. Then you need to have S-ATA drivers on a floppy when installing windows on a S-ATA disk. You don't need to have windows on C:. I have mine on E:. and I also use a raptor for OS Then you can just format the 40 gb and use it for whatever you want
