Hi Nature Mike,
As you have already moved the files and the catalog to the new hard drive, check this link on how to find missing images/folders
I would suggest you to look for the missing folders.
The images are not disappearing but after relining they should be available under the new hard drive.
Thanks!!! That's exactly what i needed. I just needed to connect the parent folder.
One more thing. For some reason two of my folders went offline. When I tried to reconnect the folder the disappear from lightroom much like the photos did. Why is this happening? and how do I find them again? I know where the folders are on my harddrive but not in lightroom now.
They should be in your Lightroom however it is possible that they are there in some other folder.
You need to search for those images inside Lightroom.
