I wanted to reformat the volume 2 to have a fresh backup (I don't use raid). Of course, instead of reformatting the backup drive, I can easily erase the directories off of root and accomplish essentially the same thing. Sorry for the stupid question although I did learn how to reformat the drive from your response. I am surprised one can't reformat the volume 2 through software alone. By the way, my unit has been reliable and has worked well but I do think the documentation leaves a lot to be desired. Thank goodness for this forum.
