Overview
The program was first introduced in MS-DOS 6.2[1] and succeeded its simpler predecessor, CHKDSK
. It included a more user-friendly interface than CHKDSK
, more configuration options,[2][3] and the ability to detect and (if possible) recover from physical errors on the disk. This replaced and improved upon the limited ability offered by the MS-DOS recover
utility.[4] Unlike CHKDSK
, ScanDisk would also repair crosslinked files.[5]
In Windows 95 onwards, ScanDisk also had a graphical user interface, although the text-based user interface continued to be available for use in single-tasking ("DOS") mode.[6][7]
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.
