I recently created an image of my hard drive and then rebooted my machine with the true image boot disk in order to verify the images. On every DVD I received a media error but when I clicked retry it continued to verifiy the images. At the end of checking all the images a message was displayed stating that the images were verified. Is it safe to assume that the all the images are actually valid? I using 8.0 but my trial ran out so I don't know the actual exact version. I would like to know if the product actually works before purchasing it.
