I have downloaded photos dozens of times into LR--no problem. Until today. When I hit Import it will show the photos on the card already downloaded, but no others. (I forgot to clean the card by formatting.) Any advice?
This just happened to me today for the first time.
I import through an external card reader, and eject the card when it is done.
I had imported a couple of dozen shots from the card, then proceeded to edit them.
Card was ejected; PS was also open, LR was still open.
I went away, and shot another dozen. Then when I went to import them, LR failed to see them. It only saw the previous shoot.
I tried a few " look here - look there", then back to the card with no success.
Eventually I used Windows file Explorer to move them to the folder I wanted, then I did a "sync folder" which saw them all.
I eventually closed Lightroom & PS.
Before I wrote this, I took another shot on the same card.
I reopened LR, asked it to import -- and it showed the new photo, no problem.
Go figure.
I believe it might be related to the current bug of LR having issues with ejected cards and hard drives.
Solution - close LR after you are done processing and reopen it for a new import.
