May I suggest you use either Carbonite or Mosey (On-line back up) You will lose nothing after that! I have backed up thousands of pictures and all my writing for my books and poetry, and even if the computer crashes, I can get another computer, and download all the files. It is a big deal to do the original backup, but after that, its goes on in the background and you will not lose a file ever again. You can go to say the Rush Limbaugh site and hit the Carbonite link and you can get the service for a year but only pay for ten months! Check it out, serious peace of mind for me I can tell you.
I have been noticing the Carbonite ads..Thanks..good advice.
