I was pretty skeptical about this until I burned a few test discs and had my way with them. I cut them, sliced them and actually removed half of the reflective layer on the disc and this application restored them every time. I would say if you're on the fence about this app then do what I did and throw your worst at it and see if it makes you a believer. They still have a lot of work to do. Documentation doesn't really exist. The price is high for something so unproven, but has a decent interface and, in my tests anyway, proved to do exactly what it claims to do which is to protect your data through redundancy and an easy to use restore process. I am really looking forward to seeing this application mature.
