Ubuntu is more sensitive to potential disk failure, and will tell you long before Windows does. Heed the messages Ubuntu is giving you. Your drive is failing. I don't care what Windows (especially XP) says. By the time Windows figures it out, you probably won't even be able to boot to the drive.
Yes, brand-new drives can fail. I've had this exact same thing happen with my Western Digital 1TB drive (it was a factory defect with that line of drives). Since it's brand new, you can get it replaced under the manufacturer's warranty. Do that ASAP.
