my hard drive died recently, and i ordered a new one. this new drive is a western digital se16 500gb. i need to format this drive, but when i try to boot from cd in post, there is a disk boot failure message: disk boot failure insert system disk and press enter. i have the XP cd in the drive, yet it will not recognize it. if you continue to press enter, the same message appears over and over again. could it be a defective HDD? would jumpers have anything to do with this?
