Possible problem with hard disk

System: Dell Dimension L466x. Windows 98SE Norton Internet security 2004.
Problem: Doing monthly cleanup with Norton. One button checkup Hard disk integrity scan. One error found in drive C the hard disk drive. Should be fixed by Disk Doctor. But that program hung up on the sub-portion Directory Structure, repeating over and over again. Could not finished the job.
So tried in Windows system tools the scandisk program. That one also hung up at one point, repeated over and over again.
My system works well. I am unaware of any functional problems. So I did defragmenting with the Windows system tools, and this was successfully completed without a problem.
Now I am bewildered. Have I a problem or not? Were it not for doing the monthly "housekeeping" I'd not be aware of anything out of line.
Thank you for your expertise and courtesy.

Hi Geezer 79

Can you run scandisk via dos mode?

 

Thank you for your reply. No, I have not run scandisk in dos mode. I am aware that such exists, but have no idea what it is or how to utilize it. Can you give me a reference to some sort of tutorial so that I may learn?
Thank you very much.
