Digikam eats (some of) my photos when I tag them

[Peter S]

Hi,

I have an unusual issue.  I have digikam installed on a linux installation and a large collection of photos on an NTFS windows partition.  There are a few directories in the collection, one relates to photos from my phone, one from my camera, etc.  These are then displayed chronologically without reference to the folder structure by digikam.

When I tag photos from my camera only, then  close digikam, they are deleted.  Only tagged photos, and only in the directory relating to my camera - but all of those photos.  The thumbs db still has a thumbnail of them, the tag database still knows they are tagged but the original file is gone.  Digikam can't open them and neither windows or linux can see the files anymore.

Anyone seen anything like this before?

Cheers

Something very similar happened here.
Long story short: I kept my photos on an external hard drive vfat, and
suddenly all the files on disk of 2016 photos (tagged) were missing. I
had the thumbnails too, until I rebuilt the database.
Luckily I had regular backups and I was able to restore data, but I
changed the file system from vfat to ext4. So far I did not
experienced the problem again, but I'm not sure it was a filesystem
problem.

% digikam --version
Qt: 4.8.6
KDE Development Platform: 4.14.15
digiKam: 4.12.0

My collection was around 290 GB.

When you tags photo, digiKam do not touch file. Tags go to the database. You can setup DK to delegate tags writting to image through Exiv2 shared libs. Certainly this library has a problem with NTFS.
