Sorry to hear you may have lost tags.  We've had sporadic reports of
users losing metadata in situations like you describe (see e.g.
http://trac.yorba.org/ticket/2968), but have been unable to reproduce
this problem ourselves.

A few questions:

- What version of Shotwell are you running?
0.72


- Do you have metadata writing enabled in Shotwell?
Where is this option selected? - I've had a look in preferences, but
it's not there.

This feature was new in 0.8, so I'm not surprised you didn't find it.  :)

- Do you have auto-import enabled?
I don't think so - as with the above, I can't see an option in
Preferences for this.

Similarly, auto-import is only in 0.8.

- When photo files are unavailable, Shotwell marks the photos as
Missing.  When the files become available again, Shotwell should
automatically unmark them as Missing so that they appear normally
again.  Did that not happen in your case?
When the directories were essentially moved somewhere else by my clumsy
attempts to get another disc drive mounted, Shotwell said all the files
in these directories were Missing (at least, I believe it was those and
only those - I didn't check them all!).

OK, good - that was expected.

I chose to Import the directories, from their new location. After a few
hours, I found that there were still some 22000 images in the Missing
Folder, although the ones I'd just imported were now available to view
in the normal way. Very few of the tags I'd applied to the files
survived the process, although I think some of the missing ones did come
back.

Right. When you reimport photos from a new location, it would be nice if Shotwell would resurrect the files out of Missing Files and apply the old tags to the photos. Unfortunately this isn't working at the moment. We're still hoping to fix this for 0.9:

http://trac.yorba.org/ticket/3132

Finally, I worked out how to mount my external hard drive in the same
part of the directory structure as it had been before, and Imported
again.

All appears to be OK now, apart from 22834 photos in the Missing box.
(Clicking on the Photos icon I find I have 22783 photos). My tags have
apparently been restored to the situation before I messed things up!

That's great!


- You said that 'only some of the tags have been recovered'.  Does there
seem to be any pattern as to which tags were recovered?  For example,
were those only tags for photos in certain directories, or only tags
which existed in the photo files before you imported them into Shotwell?
Sorry, I haven't got a handle on that. I think that the tags that were
present only referred to photos which had been imported from my camera
into Shotwell, and were in a sub-folder of my home directory, but I have
a feeling that one or two tags reappeared when I imported the first time
(i.e. from the renamed directory).

I'm reluctant to empty the Missing folder at present, but I'll obviously
have to do so in due course.

Right. If all the tags on the photos in the main Photos view seem OK, then you should be able to empty the Missing folder with no problem. Of course, it might be prudent to back up your Shotwell library before doing so if there's any chance that you still might need the tags on photos which are Missing.
