Find and detect bad sectors on hard disks with Windows Surface Scanner

Windows Surface Scanner is a free tool you can use to find and detect bad sectors on your hard drives.

The software will read each sector of a physical drive that is currently mounted on an XP, Vista, or Windows 7 operating system.  Each sector is examined for a read error. If a read error occurs the error counter will increment.

Usage:

1. Press the ‘Mount’ button. That will query your system for all physical
   Drives currently mounted.
2. Use the check boxes to the left of the drive to indicate which drive
   you wish to have the software scan.
3. Press the ‘Scan’ button. This will start the surface scan of the
   currently selected drive.  As the scan progresses the progress bar will move
   forward and a percent indicator above the progress bar will be incremented.
