Just to give a feedback to you.
Yesterday I converted all my .CR2 files to .DNG and uploaded again. It seems that this worked. The device scanned all the files again but it didn’t get stuck on those on portrait orientation. Until now everything is working fine.
Thomas,
I see your RAW photos are CR2 too (Canon). What is your camera? Mine is a Canon 6d.
I think I will replace my device for a My Cloud Home. The wd staff replied me telling that it doesn’t use ufraw-batch
