Run chkdsk /r
It will attempt to repair the errors it finds.
You are the bomb, aford10!!!
This was happening on my system, didn't have the time this week to worry about it, so just kept bypassing the CheckDisk to accomplish what I needed to. However, it was extremely frustrating.
Yesterday, I located this thread, did as you suggested, and restarted the computer.
It took awhile for CheckDisk to complete the 5 stages (about an hour), but I was patient, allowing it to resolve the issues.
The end result : perfection; I have my reliable computer back up and running as it should.
Thanks for helping us out, and have a great year. : )
