I don't have a solution for you, but if there is a disk error, you may want to run the Error Checking scan on your hard disk, to see if any errors are there.
Open My Computer, Right click the C drive, select Properties, click the Tools tab, and select "Check Now..." under Error Checking.
Make sure no programs are running on your desktop, and turn off the screen saver. You may have to disable your AV and firewall but make sure you are not connected to the internet if you turn off your firewall.
