As I can sometimes do, I did not read the directions before delving into LR. Now I find my self with image history in LR on 2 or 3 of my HD's. I would like to now consolidate it on one HD but fear in doing so I will lose the images I have created within LR. Is there a tutorio or some other way to get me back on track with this application?
Your image history (if I understand you properly) is stored in your catalog file, and nowhere else, and so it is only on a single drive.
Do you mean you have edited photos on multiple drives? This isn't a problem for Lightroom at all, the software doesn't care, and you can leave things just the way they are. But if it bothers you for some reason, you can move the photos to a single drive if you want. In Lightroom select the desired photos or folders (it's easier to do this using Folders) and drag them to the desired drive.
Alternative if you will be moving lots of folders: Adobe Lightroom - Find moved or missing files and folders
