Missing Folders and Missing Smart Previews
I have had missing folder and smart preview problems with my Lightroom Classic catalog recently.
Has anyone had the situation when the Catalog seemingly reverted back to a previous dated version? In this case my folders containing recent exports and imports disappeared and in fact, my main folder containing all my photos vanished. (not just unlinked with a ‘?’ but vanished)
Not only that, a new duplicated external HDD appeared with a ‘1’ added onto the end of its name. Very strange.
Maybe hastily, I decided to revert back to a recent back up of my Catalog. I unzipped the backup and saw the Catalog, Preview and other files etc normally associated with a Catalog.
I opened it up to find the same view which was:
Big Splicer Six (my external HDD) with my Lightroom Photos folder showing only one folder: ‘Exports’ but out-of-date and NO main folder with all of my photos. Vanished.
Big Splicer Six 1 (on the other hand) had all of my photos but they were unlinked. (greyed out with the '?' attached to subfolder names) I did what I have researched and selected a folder on the ‘1’ HDD, and used ‘Find Missing Folders’.
It worked. , It relinked the photos in each subfolder BUT listed it BACK on the original Big Splicer Six HDD. I continued and eventually, I recovered a previous state of the Catalog and no photos were lost.
Why did this happen in the first place? Why did my Catalog 'go back in time'? But at least I was able to revert my original Big Splicer Six HDD back to normal.
THEN I noticed that all my Smart Previews/Previews had gone. The ‘original’ photo was the only file linked in LR/Library/Histogram data panel, and no corresponding Smart Preview (eg) was linked?!?
Where did the Smart Previews go? ( I see the other 4 LR data files listed with the Back up Catalog version. They are all named the same) Why are they not automatically relinked to the original photo file in the Catalog? If this is a corrupt Smart Preview data file? What other course of action do I have other than remaking all the Smart/Previews? What guarantee is there that this won’t happen again? Is this a bug?
Does having over 100K of photos make a difference?
Any sage advice, thoughts would be most appreciated.
Thanks
I am using Mac OS Ventura 13.6.2. I use Lightroom Classic 13.0.2. Catalog size if over 1GB.
