The drivers are likely the SATA drivers provided by either the manufacturer of your computer or the manufacturer of your computer's motherboard (mainboard). Either of which should have a website from which you can download the driver.
I would also go to the Seagate Website (www.seagate.com) and download their drive diagnostic utility used to check the fitness of your drive, as it may be defective or failing. You could be wasting your time reloading XP if it is doomed to fail again. Make sure the drive gets a clean bill of health from Seagate's utility first.
