NAME
     sdtmedia_prot - The CDE Removable Media Protection Utility

SYNOPSIS
     sdtmedia_prot [-w] [-d] raw_device

DESCRIPTION
     The sdtmedia_prot is the change protection utility for
     removable media used within CDE.  It provides an easy-to-use
     interface that allows users to modify the protection applied
     to a removable medium.

     It allows the user to select the level of protection for a
     medium, and enter passwords if required. Removable media
     support four levels of protection.

        Disable Protection
                       This allows the user to unprotect the
                       medium. If the medium was previously pro-
                       tected with a password, the user is
                       prompted for that password before the pro-
                       tection is removed.


        Write Protect Without Password
                       This allows the user to Write protect the
                       medium. No Password is required to access
                       the medium, however writes to the medium
                       are prevented.  This protection is the
                       software equivelent of using the write
                       protect tab on floppies.


        Write Protect With Password
                       This allows the user to Write protect the
                       medium. Writes to the medium are allowed
                       only if the password is entered.


        Read-Write Protect With Password
                       This prevents any acces to the medium
                       unless the user enters the password.

     If the user selects protection with a password, a dialog
     appears prompting them to enter and verify the password.

     If the user chooses to disable protection on a medium, which
     previously was password protected, they are prompted to
     enter the password.



FILES
        /usr/dt/bin/sdtmedia_prot
                       This is the executable for the CDE Media
                       Protection utility.

        /usr/dt/app-defaults/<LANG>/Sdtmedia_prot
                       This file includes the application
                       defaults for the CDE Media Protection
                       utility.

OPTIONS
     The sdtformat_media utility defines  command-line parameters
     that may be entered to use the utility.


        -w             This instructs sdtmedia_prot to write pro-
                       tect the media without a password. As no
                       user interface is required, the GUI is not
                       displayed and the medium is protected. If
                       the media was previously protected with a
                       password, then the user is prompted for
                       the password and protection is removed.


        -d             This instructs sdtmedia_prot to unprotect
                       the medium. If the medium was previously
                       protected with a password, then a dialog
                       prompting the user for the password
                       appears.
