The very first thing you need to do is to back up any data you don't want to lose because your hard drive is having problems. Next I'd try booting to the command prompt, then issuing the following command: chkdsk /r /f . That has a better chance of working. If that doesn't work, you may need to boot from a live CD and attempt repair from that. Be prepared to replace your hard drive and reload your system.
I have a problem : After I schedule a error-check on my drive C (windows), the pc restarts and then the scan disk starts, I didn't press any key, i just let it run, but it dose nothing, it just saying that scan-disk can't access some file
and it's used by another program.
In my event log I have this error : The device, \Device\Harddisk0\DR0, has a bad block.
