Ack. Sometimes I feel like I have poor forum communications skills. I was trying to say that I found the same results as the quoted text. IE, it *does* spin down after 15 minutes like you suggested it should.
Anyway, the rest of your post is helpful none-the-less. Now I have to turn my attention back to booting, and all that, and maybe I'll remember what my plan was to do with the setup once I got it working, which is completely lost to me now.
