It does a scan of the partition and displays the number of folders, size, etc. Then it asks if I want to make it a bootable OS X back up. I reply yes, then I select the 40 GB hard drive as the destination. The options available are "back up set" "synchronize set" or "compare set". I choose back upset and it runs for a while, then it stops and says the destination is full. The one thing that I didn't see was that you reformatted or initialized the drive before you started your back-up. I try to remember to do that each time, that way I always have a clean drive without any previous data on it for my copy. By the way, I have more than one back-up drive, so I am always keeping the two latest copies on hand, and I try to remember to make the back-up every other week. Sometimes I forget and it's the middle of the week before I remember that I was supposed to do it that week, not next week.
