You have to have LR move folders or it doesn’t “know” you did it and you end up with a lot of ? over the images. It sounds like you manually moved them, you didn’t have LR move them. No big deal, you can resync everything (option click on the folders and select Locate Folders). You could have the database file on drive A and all images on drive B, no problem. As long as LR knows where the folders and images reside. Of course, best to keep everything on one dedicated drive. Makes cloning easier. SuperDuper on the Mac is awesome for this task.
