I have never used an imaging program before this but I am now trying out Drive backup Pro. I was testing and attempted to copy my hard disc image to DVD (from outside Windows via the restore CD) and had a strange issue come up. When I began the process Drive Backup advised that the image would be 10+GB in size (don't remember the exact number). I was using double layer DVDs which are supposed to have a capacity of 8.5GB. I expected that I would be asked to insert a second DVD when the first was full. Well the whole copy process went to the one DVD. The program never asked for a second DVD and the program stated at the end that the 10+GB had copied. I received no errors, etc. If I look on the disc with Windows Explorer the disc is completely full. So, what is the deal??
