Cannot boot OS?

Every time I turn on my PC, I can never boot to XP. I've ran diagnostics tests for booting the OS, and have found two errors.





The first one is:


IDE DISK S/N - READ TEST





The second one is:


IDE DISK S/N - VERIFY TEST





Everything works besides those two things. They both come up with error codes and the message that they give is:





"uncorrectable data error or media is rite protected."





Is there anyway I can fix this without having to buy a new hard drive, or anyway to boot to XP without these errors?
Cannot boot OS?
yes "IF " you still have the start up CD. Drop in start up CD and try taking it through recovery console. if that don't work then get a UBUNTU disk (Linux CD) boot live to it and us its OS to recover all the data you want save to an external hardrive or disks. then do a clean install of XP all over again. If you comp wont boot from the CD go into the CMOS (F10) at first part of boot then tell your comp to look to the CD ROM drive as the first place to look for an OS. Save then exit.
