Scan Disk

Scandisk is used to check the integrity of the file system, also to scan the physical hard disk for bad sectors. These bad sectors can lead to data loss or corruption and are one of the first signs of a failing hard disk. When bad sectors are encountered scandisk will attempt to repair these sectors or mark them as unusable.
