I've created a password reset "disk" two times and played with the results.
I think I know how it works, but I'd like your feedback as to whether this
is really how it is.
1) When you create this password reset "disk", all you are doing is
creating a file named userkey.psw in the root of that media.
2) You can copy that userkey.psw file to the root of any other removable
media and your computer will successfully use that file if the media can be
detected by the OS.
3) If userkey.psw is in a folder, it can not be used to reset the password.
4) If at any time you think that your userkey.psw is in the wrong hands, you
can create a new password reset "disk", which voids any previous userkey.psw
files.
5) If you step away from your computer for a minute, someone else can create
a new password reset "disk", thus locking out the most recent userkey.psw
you created. Depending on the jokers in your environment, you may want to
make a new password reset disk periodically.
