I've run into the "unable to display" problem a few times, where I've moved photos from the SD card to my computer. Then when I put the SD card back in the camera, the files are out of sync with the internal database. I figured out a few ways to fix that (see below) but now I'm stuck with some videos which will not delete.
In the playback menu, the videos show up with a big question mark. When I click on them it says "unable to display". If I try to delete (singly or as multiple images) it says "deleting images..." but then it's still there, and the file counter is still the same.
Does anybody have an idea how to get rid of these phantom videos? Here's what I've tried so far, which was successful for cleaning up photos but not videos.
- The camera pops up an error when I first insert the SD card and offers to correct the problem. There is an ominous warning about damaging or deleting data which was added by another device, but it mostly works OK. If not... (or if I accidentally click cancel)
- Manually delete each phantom image. Delete by date doesn't work because the date is corrupted and appears as --/--/-1 I had about 2000 images, so I lost patience with this option fairly quickly...
- You can manually trigger the database recovery by doing:
Menu - suitcase icon - 5 - Recover Image DB
- Apparently you can format the SD card, but I still have lots of other images on there, so I'd like to avoid that if possible
Bonus points for anyone who can come up with a good reason why Sony would have this database in the first place???
This is a Sony a6000, but I've read about the database issue with several other Sony cameras, so I don't think it's specific to this model.
