I am running my computer like I have in my sig. My problem is does anyone ever try to run defrag on winXP with this raid set up. It tells me that it cannot defrag because I am using an NTFS file system. Which I am only using this type because I have both my hard drives hooked up to my serial ATA in Raid 0 mode. I have no hard drives connected to my ide cables. Any help or explanation to this would be greatly helpful. Thanks
