What I would like is to ‘archive’ video metadata after I have moved video files to an external drive. And then when I feel the need, I can reattach the drive, and reload metadata for the media that is currently stored offline on the drive. 

My understanding is that when you do a scan of the video directories, that the metadata for missing files(archived to external disk) is wiped out of the video metadata table(has been so in the past.

Mythadder was very useful in keeping offline video metadata available in a table indexed by the drives UUID  that was then accessed when the given drive was plugged in again in the future.

The key is ‘remembering’ the video metadata for video that was moved off to external access. And then being able to reload that data when plugging the drive back in in the future.

Regards!
