Scandisk vs. Norton Disk Doctor

Dear Experts:

      It is a well-kwown fact, that in case of erroneous shut-down and/or emergency restart of Windows (say, by pressing Ctrl-Alt-Del or Reboot button), during the re-loading Scandisk is initialized automatically.

      Now, if we have Norton Utilities istalled on the machine, in similar cases HDs are scanned by Norton Disk Doctor, that replaces Scandisk in its role of a utility for emergency diagnostics and recovery.

      The question is how is it done? Where is the reference to NDD.EXE (instead of Scandisk) entered? Is it in the Registry or somewhere else? And how can it be corrected, because I'd like to remove Norton Disk Doctor and get back my Scandisk for emergency procedures.
      Please, give me some brilliant hints.
      Thank you.
      Respectfully, PPdanila

During the installation procedure for NDD, the installation Wizard will ask you if you want to disable the Windows' Scandisk and Defrag Programs and use NDD's Scandisk and Defrag.  Since NDD scandisk starts up when there is a problem with your hard drive, you must have answered yes when asked if you wanted to disable the Windows commands.  

Since you want to remove the Norton Utilities, all you have to do is open the Control Panel in WIN95, and go to the Add/Remove programs icon.  Highlight the Norton Program  and click on Remove.  Windows will safely and completely remove the program for you.

Wonderful, but I am not going to unistall Norton Utilities. I simply want to learn how to deactivate NDD and get back Scandisk or vice versa. I am almost sure it can be done by editing some configuration file(s), probably certain entries in the Registry. That's why I need advice from the Experts.
Thank you.

From the information I saw at:
It appears that NU simply overwrites the win.com file with its own version so reextracting from your installation disks should do it

And what about the reverse manipulation, i.e. if I want to substitute Norton Disk Doctor for Scandisk? Is it possible?
