The Cavier SE 80GB HDD stops my PC from booting up and so I couldn't install XP on it even if I made the CD Rom as the first boot device. The xp disc would only start loading if the HDD were unplugged before power up. Hence, in order to install the windows xp on the HDD, I had to unplug the HDD prior to power up and then replug it in after xp start loading. What's wrong with the HDD? Thank you!
