I am pretty sure they are two separate drives. So if I understand correctly when I create a image of one drive and have it copied to another, whatever files, folders, etc are in the other will be condensed? Even without the computer asking me if I want them to? As for the iso files, i've looked and I having a difficult time located anything that I can open with my iso, but I will continue to try. I want to include a screenshot of what my drive looks like, but I am uncertain as to how to post a pic. I will keep u up to date and again thank you for your response.
