Check Disk (Hard Disk) for bad sectors with the free software Windows Surface Scanner. This is a free disk scan utility that scans your hard drive rapidly and reports any sector errors in them.

Bad sectors in hard drives may lead to computer instability. Hence it is imperative to scan the hard drives for bad sector errors and fix them. Windows Surface Scanner works by reading each sector of the physical drive that is currently mounted on a Windows 7, Vista or XP operating system. The sector is examined for a read error and if it detects any read error, it automatically increments an error counter maintained within the program.
