Scandisk


Scandisk is a utility for locating, reporting and correcting file system errors (such as lost file fragments and cross-linked files) on disks (hard drives). Scandisk was originally included in version 6.2 of the MS-DOS operating system, but there are also versions for Microsoft Windows 95 and Windows 98. Scandisk is generally preferable to chkdsk because it has better error recovery features and can perform a more exhaustive surface scan if needed.

Scandisk utility can’t check NTFS volumes, so it’s not included with versions of Windows that could be running on NTFS-formatted disks – basically Windows XP and later.
