First of all...thanks for your help guys. I know I can always turn to this site when I get stuck...and i'm stuck!!! I have an Asus A7N8x-E dlx V2.0 and I'm trying to clean install Win XP Pro to 2 WD 74gb Raptors in RAID 0. I got the jumper set, and RAID set up using the bios utility. I boot off my Windows CD, Press F6, takes the drivers from my floppy and begins installation. I've tried this twice already. The first time, It asked for the partition where I wanted windows installed and It gave me 2 options. A 140gb and a 70gb. I figure that if it's set up as Raid 0, the 140gb partition should be there since to my understanding, it's two 70gb hds treated as 1. So what is the 70gb partition doing there? anyways...It went throught the format process, got to 50% and then took about 20 secs to jump from 50 to 100 percent and gave me an error message saying that there is a problem with the hd configs. I went back to the RAID utility, deleted it and reinstalled it again. Now this time at the partition option it gave me 2 70gb. It formatted, copied the "necessary files", rebooted and then it gave me another error message saying that the OS cannot load. My questions...after setting up the raid 0, how many partitions should I see at the partitions options screen? one 140, one 140 and a 70, or two 70gb partions. At the boot options, right above option 1, 2, 3 etc, i have a "SCSI or RAID card boot" option which I enabled. My first boot device is the cdrom and the second is SCSI. Thanks!!!
