I have ATI 11. Im looking to simply disk image two separate drives. After great pains, i finally got my new system dual booting to Vista Ultimate on one hard drive and XP Pro on another dedicated hard drive. The XP Pro hard drive suffered an MBR hiccup that required a reinstall of XP pro, and subsequent resettign of the dualk boot. Wasnt too painful now that I know he steps, but I have it exactly perfect and want it protected in case it happens again. In ATI 11 I am having semantics confusion. I just want a simple image burnied to a DVD. It appears that ATI calls this backup/restore? But when I tried to backup my XP pro install (20 GB on a 149 GB drive) and tried to put it on a 500 GB external (with 400GB available) it says the disk is full?!? Im confused. Am in fact using the wrong tool for the job? Can you make a bootable ISO DVD using this app? Many thanks!
