Lightroom not detecting duplicates

I have all my lightroom photo's on an SSD. Recently i purchased an identical SSD and made a clone.

My plan was to take SSD 2 travelling, so I could add to my library and edit existing photo's and then once I return from travelling merge the 2.

What I've noticed is that, on my desktop machine with SSD1 as the catalogue. If I try to import files from SSD2 to my lightroom catalogue on SSD1. Lightroom will not detect duplicates. Despite the files being identical, byte for byte. With the 'don't import duplicates box checked' lightroom will still import duplicate files and rename them 'FILENAME-2.DNG'.

Why is it doing this?

Oddly, it will detect duplicate jpegs, just not duplicate DNG's.

      Don’t import photos from the clone disk. Use “Import from Another Catalog” and import the catalog from that disk (where the edits that you made on the road are stored) into your main catalog.

      This is not an acceptable answer Johan, this is a cop-out. There are plenty of times when copying from another backup is a valid part of a workflow.

      I am still encountering this problem in 2022 with version 11.3.1

       

      They are the same image, same size, same date/metadata, and same MD5 checksum. Lightroom should be able to figure this out.
