This is not typical and may be indicative of a pre-existing problem.
Power off
Desktop:...Open the case and reseat the hard drive IDE ribbon cable at both
ends.
Laptop/Portables:... simply remove and reinsert the hard drive.
If that fails:

Otherwise go to the website of the hard drive manufacturer and download
their hard drive diagnostics.
Do you have a hard drive overlay such as Max Blast?
Windows XP sometimes has issues with overlay software.
You may need to perform a Clean Installation without their overlay software
which is not needed anyway.
