I was backing up some files from an iPad Air 3 to a flash drive 128 gb usb 2.0. It backed up a few dozen graphic files without any problem. I did about a dozen at a time. It did need to be plugged into the outlet and I have the dongle, of course.
Then I increased the number of files to back up at a time. It was spinning far too long I thought so I stopped it. Since that point the flash hasn’t been working. It will tell me on other devices (an iPhone and an iPad mini) that there is not enough power. It does not recognize it all on the iPad Air.
Is there anything I can do? My Apple devices are running just fine, knock wood.
