/CHECKONLY   Checks a drive, but does not repair any damage
/CUSTOM      Configures and runs ScanDisk according to SCANDISK.INI settings
/NOSAVE      With /AUTOFIX, deletes lost clusters rather than saving as files

             summary screens
/NOUI        Uses normal DOS interface instead of graphical interface
/SURFACE     Performs a surface scan after other checks
