The external HD that held my LR4 photo originals fell on the floor. Although it kept spinning, the directories were all empty but slowly recovered over a 4-6 hr period (Lacie d2 quadra). Nevertheless, I would like to take a conservative approach on a filesystem that held 25k originals. I have a recent backup, but it is one import behind my current catalog, and I do not have a catalog backup that matches the backed up photo library. But I still have the originals from the last import.
One idea I had was to save the recent (uncataloged) subfolder, recover the photos from backup, re-add the subfolder, then open LR with the most recent catalog. Would that work?
Although I was an experienced Unix DBA & backup & recovery expert, there is not a lot published on LR internals & db recovery.
Any advice or references would be appreciated.
