=== SCANDISK ===
{{Main|Microsoft ScanDisk}}

Disk diagnostic utility. Scandisk was a replacement for the <code>chkdsk</code> utility, starting with MS-DOS version 6.2 and later.<ref name="RUNNINGMSDOS" /> Its primary advantages over <code>chkdsk</code> is that it is more reliable and has the ability to run a surface scan which finds and marks bad clusters on the disk. It also provided mouse point-and-click [[Text user interface|TUI]], allowing for interactive session to complement command-line batch run.
<code>chkdsk</code> had surface scan and bad cluster detection functionality included, and was used again on Windows NT-based operating systems.
