I exported my LR catalog as a catalog to a portable hard drive and I got the message that "Photo previews could not be found" for some photos. This message listed 663 of the 6267 photos exported. What does this mean and how do I fix it? Thanks in advance for any help.

I don't think there is anything to worry about. The previews are just the larger images that LR can display in Library mode when culling through the images in a LR folder. If you come across a folder that it seems to take forever to load a preview, then you can tell LR to just rebuild all the previews in that folder. Check your LR Catalog Settings and set them to a standard preview size of the size your monitor can display or smaller, Medium preview quality and automatically discard 1:1 after either a week or month. Otherwise your previews can use much space on your hard drive.

That answers my question. Thank you very much!
