Using Win 10. When importing from sd card to external hard, some of the raw files are imported and others are not. I have used two different readers and changed ports and it seems to still not help. In order to import all images I'm required to redo task more than 10 times, each import with different amounts of images. In the middle of importing, LR will stop and sd card disconnects and reconnects. Error messages are then displayed: corrupted files, images missing, no disk space etc. I'm not sure if it's the sd card itself or what. I would like to avoid having to put images on computer before importing. Please help!
