I don't have that answer. But given how cheap hard drives are, I'd replace it and move on.
I have a Dell XPS 410 desktop with Windows XP. I had to reformat it and reinstall Windows. Now, every time I do anything on this computer, the hard drive makes a clicking noise, then it freezes for a few seconds. Sometimes, I'll even get a Blue screen! and I have to shut down completely. Can anyone tell me why my hard drive is suddenly doing this?? Granted, the computer is a few yrs old, and I've had problems re-installing Windows XP and all the updates, but why would the hard drive start doing this now?
