I repeat a time or 2 and get the all the files imported but later some were found to be corrupted. I open LR and try to import but get Disk not ejected messages (from both hard drives and the SD card) about half way through the import. The SD card and both HD show up in the finder. And the dongle is connected to the power brick and the MacBook You also have the option from the iPad to import it directly into Lightroom (on iPad) or into Dropbox too. I then airdrop it directly to my Mac and then import into Lightroom. I put the SD card (or sometimes an XQD card) into a Lexar card reader which is plugged into a third USB connector on my dongle. I do this often using the SD card to lightning adapter from Apple. I connect another USB to a second portable hard drive labeled LR_Backup and LR is configured to import the pictures to the primary HD and deposit a backup copy on the other hard drive. Now I connect one USB cable to a portable hard drive labeled LR_primary. This dongle is supposed to be able to power portable hard drives. The dongle for the MacBook is a Kanex K181-1042 4 port charging hub with 4 USB connections and a power feed through. First the MacBook is a new 2017 12 inch with i7, 16Gb memory, and 512 Gb SSD. If the SD card reader is not working properly, your SD card, of course, won’t be able to show up on the computer.

Change SD card reader and reconnect to your PC. After my 21 day trip I had about 16100 pictures and 400 corrupted files on my hard drives. When the SD card disconnects or disappears randomly, you can retry to insert the card to the computer again to see if it’s stable to be read. My problem is that almost every time when copying files from the SD card (or XQD card) I get “Disk not ejected properly” messages. This is a long involved post so I hope you can stay with me. Some users report that the device can access the SD. I am having a problem importing from my SD card to 2 LR hard drives which are connected to the MacBook using a dongle and am looking for advice on how to troubleshoot or a better way to do save my picture files. Owners of both the new 14-inch MacBook Pro and 16-inch MacBook Pro have uncovered issues with the ability to mount and utilize some SD cards.
