I am using Acronis True Image 10.0 with Windows XP and a iomega external hard drive. I have been using this configuration for some time now without any problems. Recently, my computer has been acting up, so I want to clone my hard drive in case something does go wrong with the computer. I thought that I would format the external drive and go through the cloning process. My problem, and question is, when going to the disk cloning wizard, it says that the source disk must be removed after cloning. I don't want to do this at this time. I only want a cloned disk to use in the event that the main drive or computer crashes. I want to have the option to clone everything back from the external drive to a new computer if need be. I've heard that the active drive can be cloned to the external drive with no problems as long as the external drive is disconnected after cloning. Any advice?
