    Hi Tim, I think you suffer from a fear of "fisk" :-)      Yes you do 
need to be careful. Look at it this way:

    If your going to make a software raid-1 on Linux you must use a root 
Terminal. A root Terminal is capable of deleting your entire Linux! :-(

    This paper is not for a person who has no knowledge of root and what 
it can do. You need to know the basics. I will add a place where they 
must show this basic knowledge or not try to do raid-1.
