RDISK /S and RDISK /S- Options in Windows NT
This article was previously published under Q122857
3.50 3.51 4.00
The RDISK utility included with Windows NT version 3.5 or later has two
command line options:
When you use the RDISK /S option, the program skips the initial Create
Repair Disk? dialog box and goes directly into saving the configuration.
When you use the RDISK /S- option, the program also skips the Create Repair
Disk? dialog box, saves configuration, and then the program quits.
WARNING PLEASE READ:
Both of these options also overwrite the saved SAM._ and SECURITY._
registry hives created during initial Windows NT Installation. The default
administrator account and password used during Setup is all that is
contained in these small files.
If you choose either of the above optional switches - Rdisk copies the
entire current SAM and SECURITY database files containing ALL users and
groups into the repair directory. On a domain controller containing many
hundreds or even thousands of users these files can become very large which
will Inhibit the ability to copy them to the emergency repair diskette
Be sure you have enough disk space when using either of these switches on Windows NT Machines and Domain Controllers that have a large number of users and groups defined.
As a precaution - you should make a backup copy of the %systemroot%\repair
directory to ensure you will still be able to make an emergency repair
diskette after running RDISK while using one of the above switches.
