A few older files seem to have lost their edits
Looking at my older photo shoots I can see that a few of them have lost all their edits. I still have low resolution JPG exports as a reference but all the RAW files are back as they were straight out of my Nikon camera. I can see all the XMP files are still there alongside the NEF files but when I open them in a text editor I can clearly they have all been reset.
I should point out that these files have been transferred to an archive drive, but this is something I do on a regular basis but the edited XMP files always transfer to the new drive along with the RAW files. I can see the majority of all my other shoots have retained all their edits.
Unfortunately I don't have any Lightroom catalog backups going back to 2014 so I am assuming these will need to be re-edited if I want to restore the work I have lost. I don't mind doing it for a small shoot but I would be distressed to see this happen on a big shoot so I really want to prevent this from happening again.
What could cause just the odd shoot to lose data from the XMP file?
