" The only catch is that you have to buy one of our drives to get it."
No, that's not the only catch. The real catch is that if you don't have a WD drive installed in your machine then you can't install the software. I bought a new 2.5" WD drive for my laptop assuming that the download would work as advertised and was extremely disappointed when WD tech svc. told me that the originial HDD in my laptop had to also be a WD before I could install and use the Acronis product. I had to hand over the $40 for the full version of Image Home.
I'm pretty unhappy with WD over this.
