Question

I teach digital photography at a University. Some students work on Macs, some on Windows. There were issues copying or adding images upon import

We are working in LR Classic. Students were working on drives that were formatted to match their OS–Mac Extended Journaled for those on Macs using spinning drives, APFS for those on Macs using solid state external drives, and NTFS for those working on Windows. 

Many students were not able to copy or move files into their LR catalog upon import on both Macs and Windows–the external hard drive was not available–and showed up as red with a warning. Many of the students were not working with card readers.


The workaround we came up with was moving the photos into the desired destination folder in the finder, and then trying to import by using the “add” function. However, for several students, the “add or move” function wasn’t available and only the “copy as a dng” or “copy” were, but not to the external drive. It worked later for some of the students, I don’t know if they restarted the program or not, but this was an issue for students using both Mac and PCs. It was a full class and I was often at another student’s computer when they did it.

What’s going on? I would contact Adobe tech support, but because it’s an institutional license, that isn’t available to me–I have to go through numerous hoops to get to the University’s admin, but the students need an answer sooner rather than later.

    I can’t speak for Mac’s but for your Windows users, make 100% absolutly sure that the folder containing the catalog is NOT under OneDrive.   By default Windows puts the Pictures folder under OneDrive and by default Adobe puts new catalogs in the Pictures folder and that is a recipie for catalog corruption.   While not as prevelent on Mac’s there are similar reports when catalogs are under similar ‘cloud sync’ systems.

    AFAIK, nothing changed, but this is indeed a bit confusing. ‘Removable’ in this case is like a memory card. Lightroom Classic can be a bit peculiar with that. Add a folder called ‘DCIM’ to a flash drive and Lightroom Classic will think it’s a memory card (maybe the formatting plays a role too, I never tried that). If Lightroom Classic only offers ‘Copy’ and ‘Copy as DNG’, then that is definitely what’s going on.

    Thanks Johan. In one case, that might be the issue. She was working on a drive formatted to APFS, the standard for working on solid state drives to be used on Macs. But what if the images were not in a folder called DCIM? 

    About ½ of the students are working on photos taken with their phones, and airdropping it to their computers.

    There is a variety of different operating systems, ages, and capacity constraints involved. We formatted every drive based on the end computer they were using. There are new iMacs for students that want to use them, but not enough for the whole class to use at once.

    Students across the spectrum were having the same issue.

    I’m afraid that while I’m pretty sure I know what caused it, I do not have a solution that will work for everybody. Reading your initial post again, I noticed the part about the drives shown in red with a warning. That normally means the drive is (almost) full...

    I have to say, I always keep my photos themselves on removable volumes. My catalog is on a removable raid unit (16 tb of storage) and the most recent training shows that in the library model, it references the photographs wherever they are–external hard drives, pictures folder, desktop, etc–there’s even a way to store them on dropbox.
     

    These drives were formatted for the operating system they were on (Mac OS Extended, APFS, NPFS), and were used last semester by students using high capacity flash drives.

    Some of the students were having issues yesterday using external hard drives as well as high capacity hard drives.

    Has something changed?

    Lightroom Classic does not allow you to store images on a removable volume, so this sounds like the external drives used are not seen as an external hard disk, but as a removable (memory card, flash drive).

    Thanks Johan, for your response. However, I’m not sure about this–I’ve used external drives for years and not have had an issue. Please see response above.
