ScanDisk checks and repairs file systems and bad data clusters. ScanDisk is a system utility which is bundled with and all Microsoft Windows Operating Systems.
Scandisk was programmed to check the integrity of the hard disk drive to ensure that there are no significant issues which could corrupt your computer data. It is used to scan your hard disk for errors caused by improper shutdowns, viruses, etc.
It was first seen in MS-DOS version 6.2. Previous versions of MS-DOS had only a very basic, purely text-based program called CHKDSK. From Windows 95, SCANDISK added a GUI (Graphical User Interface).
The disk scanning utility bundled with Windows NT, Windows 2000 and Windows XP is also called CHKDSK and has the ability to check NTFS disk drives. From Windows 2000 onwards, it has been integrated with Disk Properties under the title of “error-checking”.
The ScanDisk utility is owned by Microsoft, which originally purchased it from Norton (now Symantec).
Scandisk can scan and correct errors in your computer and can fix damage caused to critical Windows files, thereby improving system performance.
