Smart Previews Not Loading

My Smart Previews are not loading when I open a folder in which my originals are stored in an external hard drive that is off-line. In each of two folders I've opened, a handful of Previews load, but that's it.

I appreciate any help you can offer.

Smart Previews may not load fully if Lightroom cannot find all the data it needs. This can happen when the external hard drive with the original files is offline. Even though Smart Previews should work without the originals, some previews might be missing or broken. Try turning on the hard drive once to refresh the previews, then close and reopen Lightroom.

Sounds like your previews cache may be corrupt. Open your catalog folder and move 'catalogname previews.lrdata' out of it. Leave 'catalogname smart previews.lrdata' in place. Start Lightroom and see if this helps. Initially you will see no previews at all, but then Lightroom should start rebuilding the cache so they'll appear one by one.

So just to be clear, even though it's my Smart Previews that aren't loading, I should move the previews.lrdata folder. Thanks.

Yup. I know what I need to do. I do have one more question though. My SmartPreviews.lrdata file is date Sept 19, 2020 as Create Date and Date Modified. Would that make a difference? I'm just curious. I am going to set up my External Drive as the source for my pictures and not Dropbox.


No, ignore that. The previews 'file' is not really a file, but a 'package'. That is a folder that looks like a file and can be double clicked like a file to launch an application. The modification date of a package is often not updated when the contents changes. Even the size is often not correctly shown by the MacOS Finder. This is a known issue, but it has no relevance to your problem.

How sure are you that you actually have smart previews of these images? It should say Original+Smart preview under the histogram when you select the image in Library.

Yes the photos have Original + Smart Previews under the histogram.

Weird then it should work and it should revert to the smart previews automatically if the originals are off line.

I should add that the Previews I see appear to be photos I've edited or rated although I am not 100% certain.
