In computing, CHKDSK (short for "check disk") is a system tool and command in DOS and Microsoft Windows (and related operating systems), as well as Digital Research FlexOS, [1] IBM/Toshiba 4690 OS, [2] IBM OS/2. [3] It verifies the integrity of the file system on a volume (usually a partition) and attempts to fix logical file system errors.
Disk diagnostic utility. Scandisk was a replacement for the chkdsk utility, starting with MS-DOS version 6.2 and later. [1] Its primary advantages over chkdsk is that it is more reliable and has the ability to run a surface scan which
Microsoft ships this utility with Windows 98, Windows 2000 and all subsequent versions of the Windows NT family of operating systems. In Windows Vista, Windows 7 and Windows 10, System File Checker is integrated with Windows Resource Protection (WRP), which protects registry keys and folders as well as critical system files.

Standard DOS utility programs: APPEND: Set a search path for data files. ASSIGN: Redirect requests for disk operations on one drive to a different drive.
However, ScanDisk cannot check NTFS disk drives, and therefore it is unavailable for computers that may be running NT based (including Windows 2000, Windows XP, etc.) versions of Windows; for the purpose, a newer CHKDSK is provided instead. On Unix-like systems, there are tools like fsck_msdosfs [8] and dosfsck to do the same task.
Many of these tools were originally designed to boot from a floppy disk drive. The Ultimate Boot CD made it possible to run them on a PC without a floppy drive. [5] UBCD can also run from USB for computers without an optical drive. [5] The UBCD website has relatively good documentation for using the UBCD, and a discussion forum. [6]
TestDisk is a free and open-source data recovery utility that helps users recover lost partitions or repair corrupted filesystems. [1] TestDisk can collect detailed information about a corrupted drive, which can then be sent to a technician for further analysis.
