Unable to "export unmodified original" photos to SSD

Seeing same issue trying to export videos/photos from Iphone 15 Pro to a Samsung T9 SSD. Not sure why export unmodified original has the issue, but it may be with videos/photos that were imported into my phone and not shot natively. In the couple example filenames it complained about, they were videos I had imported from another camera source into my phone at some point in the past. As a workaround, It appears that using the "Save to Files" option instead of the Export Unmodified Original seems to work and not have permissions issues. I'm not sure if there's a downside to using Save to Files vs Export.

I'm getting the same error message. Its transferred a few pictures and then stopped and keeps giving me the same - you don't have permission error.

I am having the same issue every since I replaced my old phone with iphone 15 pro max. And because of the usb c port, I figured it is finally time for me to backup all my photo to a external ssd.

Having the same issue as the OP mentioned above, I also figured the "Save to FIles" is a workaround, HOWEVER,

Save to Files will remove meta data, the time these photo and video was original taken was replaced with the time this Save action happened which is not ideal(not sure about GPS information, havent taken a look at that). Also it saves the edited files rather than the original, meaning if you have a video you edit(shortened) in you photo and use save feature, it will save the shortened one rather than the full lenght one, not ideal!!!

...hmm works for me in a quick test. exFat (MBR) SanDisk 128 GB thumb drive formatted in MacOS 14.3.1. iPad Air 2022 images "Export unmodified original" and also "Save to Files" copy OK, metadata OK.

Maybe reformatting as APFS (or as exFAT (MBR) if exFat is really needed) on the Mac would fix this?

Yeah I think the modified date will show the day it’s copied when you save to files but the picture meta data still seems to preserve the date the photo was taken and the location data. If you swipe up on the photo you can still see all the correct meta data. Then saving to camera roll from that file save still comes back into camera roll with correct meta data. So I think it’s not losing anything but correct me if I’m mistaken.

I will definitely try that. Thanks.

But when I encountered this issue, I also tried to use internal storage rather than external SSD, exporting to internal storage also gave the same error. And I assume internal storage should statisfiy whatever iOS requires.

Have you try export a big batch of files? Cuz whenever I export small batch like 10 to 50, it works. But once the file count goes to 500, or 50GB, it never worked. So I suspected the issue is related to some internal limitation of file size/count.

I have an iPhone 15 Pro Max. I can't export any other photo(s) ... iPhone continually gives me the error "...you do not have permission..." as stated by OP.

The only way I can make it work is by going to the "Library" and ALL PHOTOS. If I do it from Albums it never works.

While Apple support tells you to export unmodified originals to save to an external drive, it will not work on my iPhone 15. However, when I choose "Save to Files" instead and use "Browse" at the top left to navigate to the external drive, that works just fine. Maybe it won't export the original unedited images but at least it saves them at all.
