I haven’t come across this error in a while. I saw it today on a Dell D620 laptop and after a quick search I found this article in Microsoft’s  website —KB 830088.

In my case, booting from my WinXP disc and going to repair options to run dskchk /r did the trick (Method 1). It does take a while for it to run though, so keep this in mind. I left the D620 running overnight. Good luck.
