If I go My computer > Select some drive > right click > click 'Properties' > Tools (tab) I get 3 choices: Error check, Defrag and Back-up.

I ran the Error check on my slave drive. After a while it said "Disk Check Complete." That was ALL it said. Was it checking the disk for corrupted sectors or what?

Next Question: What is it Backup is supposed to back up and where and how?
