Wasting my time?

 Trying to use this device to back up my iPhone SE.    

 Specifically, photos. I’ve wasted many an hour.  

Most photos keep the busy wheel going for minutes on end then fail to copy.    

  1. formatted on PC “exFAT”

  2. turned off iCloud

  3. when it does copy a photo or two, it takes many minutes.  

Please help!

are your files on iCloud? do you have a stable internet connection?
