Hi, i am in Lightroom and with My Book Sudio external hard drive. 2017 is illuminated and I can develop those photos. Going back to 2015 and 16 it is not illuminated and I see the photos in Library but they cannot be found in Develop. Never had this problem before. Tried but cannot get them to illuminate so I can work on them. Thank you for your help
From what you said, it sounds like the LR catalog is on your computer's HD, and your images are on the xHD. This should not matter, unless, as OP have said, something got moved so that LR cannot "read" the images on the xHD. I will use these locations in my answer to you questions.
In my experience, a folder is grayed out when it is empty or inaccessible. Those images can still be on your xHD, but LR cannot find them.
Try going into the images on your xHD independently of LR. With LR Catalog open, you can compare what is in the different folders. If the images you cannot access are in those folders on your HD, then there is the definite possibility LR just cannot find them. [All file names and extensions should be the same for every image.] Any virtual copies will be represented by an .xmp sidecar rather than an actual image in the LR folder on your HD.
In that case, look at the images in Library and see if there is a small square in the upper right of the border with an "i" in it. If so, click on it and it will let you go to your HD folder and locate the "missing" images. When you find one, LR will also find others that are nearby, so you do not have to do this for every image.
I think this ought to help.

However, there is another scenario to consider. I am not sure how it happens, but sometimes I have images in the xHD folder that are different from the LR Catalog on my computer HD. These represent various edit versions, or accidental duplications, etc. If what I have said above does not work, you may have to do some importing [even though that should be the LAST RESORT]. When you hit import, it lets you choose which location and which folder to examine. Once you have chosen from one of the files you cannot see in Develop, it will show all the images in that file, those that ARE imported already will be grayed out. Ones that have NOT been imported show up bright. Very important: if you do choose to import them, and then attempt to put them into the appropriate folder, you might get a message that they cannot be put there because they already exist in that location. This indicates that they are on your xHD, but still may not be visible to LR on your computer HD. In that case, the only way that I know to get them back to being visible is to make a small change to the file name in the metadata panel on the right-hand size of the Library. Such as adding a letter or a number separated by a dash -1, -2, etc.
Pretty confusing until you figure it out. This process will let you both see and develop your images. BUT you will end up with identical images in the folder on your xHD that have slightly different file names! It can be very time consuming to go through and identify the duplicates, and to delete the one that is NOT showing up in the LR Catalog. This is one very good reason why importing should be the LAST RESORT. I had a problem like this that developed during the time when I was learning to use LR, and has not occurred again since I got better at organizing things the way I want. Somehow ended up with approximately twice as many images on my xHD that should have been there! Getting rid of those definitely gave me more space! Apparently there are programs that will find duplicates, but I have not tried them, did all my correcting manually a little at a time.
