Lightroom Classic: Not all images are being imported from my card

The import process appears to go smoothly with the slider showing progress until complete. After import, the card is ejected. If I put the card back in the reader, all the images that have been imported are greyed out. As I scroll down the images, I find several that have not been imported. I run the import again on these images, repeat the process of removing and replacing the card, and all images are now imported. I know I have lost images prior to my discovering this. All the images are in one folder on the card and the images that are not imported are in random locations on the card, not at the beginning or end.

Lightroom has known issues with file handling, and these are exacerbated by the latency issues memroy cards have.  I never import from memory cards.  I verify-copy using the OS to an external RAID array (which is twice-backed up) and then use Lightroom to import from the drive.

Once I confirm the import was complete, and the RAID array has been backed up to the first back-up array, then and only then do I format the memory cards.

I've never lost an image following this workflow.  I also never ask Lightroom to perform functions it simply isn't any good at.

Thanks, I will mirror your workflow. I was not aware until now that Lightroom had these issues.

It's just a safer method.  I never allow LR to move anything; I would rather use the OS and then have LR locate the missing folder.  Locating it does well; moving...not so much.  If LR hangs, freezes, or crashes, anything in a move or copy process is subject to loss.  Drag & Drop under LR is worse.  If it hangs then, you're generally screwed.  (See the many posts regarding this problem.)

The OS, at least Mac OS, maintains the source AND the destination unless and until the move has been completed.  If, using a Mac, you chose to verify the move or copy, it will take a little longer, but you're guaranteed success.

The final point regarding the memory cards is they are not designed for high-speed continuous file operations.  Their duty-cycle is less than 85%.  LR has no idea, and simply pulls files without any verification.  Why Adobe designed LR to essentially bypass critical OS file management is beyond understanding.

Going from card to drive via the OS at least ensures that if the memory card has a latency issue during the file transfer, the source image is not lost forever as the OS is designed not to delete the source unless the destination file is present.

on Import, Not from ‘Device’, specifying mounted volume (with include subfolders), all images imported in my case.
