Hopefully this is just something stupid I've done without realising it but...
In Library view in my 'Client Work' catalog my main image drive, a Raidon RAID unit, is no longer showing up. The drive is mounted and awake and shows up in my Personal catalog.
I've tried 'Add folder' and adding the Raidon drive at root level but the Import dialog opens and shows thousands of photographs greyed out (already in the catalog). See screenshot 1.
UPDATE: I just opened yesterday morning's backup of that catalog and have found that the Raidon drive is mounting and showing up but in an unusual way. See screenshot 2.
Has anyone seen this before?
