Hello all, about two years ago I bought a PNY USB flash drive, 64 gb. I dumped about 15K worth of photos from my MBP and put the flash drive in my desk where it sat.

Today I opened the flash drive to view what photos I had. I went to add about 75/100 more from the photos app and could see in finder the new photos I had added.

I successfully ejected the drive once I was done. Well none of the new photos saved to the flash drive. I can see all the photos from before but none of the newly imported.

I repeated the process, inserted the flash drive, opened finder. Then I open photos and drag the photos I want into finder under the flash drive name. I'm pretty sure this is what I did to import them last time.

Am I doing something wrong?
 
I think dragging to external drives from photos directly might not actually work. If you try to drag your photos out on the desktop and then try to move to the flash drive, that might work

Just tried an experiment here.

1. I opened Photos
2. I selected a couple of pics (from within the Photos app)
3. I then "drag and dropped" them into an icon representing an SD card mounted in a USB connector (the SD card is NOT normally used for pics and was not formatted in a camera).
4. The two images "copied" fine from the source (Photos) to the target (SD card in USB adapter).

To repeat the test, I attached an OLD Sandisk USB flash drive, and tried copying from Photos to the flashdrive.
Again, it worked.

So my -guess- is that the OP either
1. Did something wrong during the original copy
or
2. Has a possibly-defective flashdrive
or
3. Has something else of a problem.

Some questions:
What format is the flashdrive?
Is it possible the flash drive is almost filled up with files?
When you tried to do the copy, did the "+ sign" appear over the icon of the flashdrive as you dragged-n-dropped?

WHY I asked that last question:
I have seen instances where I mounted a USB device (in my case the SD card in a USB adapter above), and when I attempted to do a drag-n-drop copy, there appeared a small "prohibited" sign over the device icon, and the files would not copy.
However, if I ejected the device and then re-connected it, the copy went ok.

My advice:
Try A DIFFERENT flash drive or external storage device.

By the way, DO NOT "trust your photos" to only one device.
Not even two "is enough".
You need THREE COPIES:
1. Copy 1 in the Photos library
2. Copy 2 on your primary backup
3. Copy 3 on the secondary backup.

Thanks for the reply. I’m actually thinking the flash drive may have went bad?

Didn’t have any issues two years ago when I imported a bunch of photos the first time. And those I can view no problem.

And yes, the + sign does appear when I drag and drop over the flash drive icon.

I can see the photos on the flash drive. Then when I eject and re insert the drive all the newly imported photos are gone.

I’m gonna but another drive and try the methods described above.

All my photos are in the cloud, on an extra iPad I own, on my Mac and saved on my time capsule.

But I wanted a flash drive with a good amount on them too.

Thanks
