Please explain further. Be sure to include the exact version NUMBER of Lightroom and your operating system version. Do not tell me "up-to-date" or "current".
In particular, I do not understand why you are viewing the backup drives in Lightroom, shouldn't you be viewing the originals using Lightroom?
I also don't understand "disappearing". Please provide a lot more detail about where you are looking and what you see that indicates "disappearing".
Lastly, if you cannot upload photos, state exactly what happened and what the exact word-for-word error message was.
Hi , and thank you from the start. I am using Lightroom 5.7.1 on a 2013 Macbook pro version 10.11.6.
I always plug in 2 backup drives, and import my photos onto both for lightroom. (I look at the pictures and edit via lightroom, but if I'm not plugged into either, the exclamation mark comes on to say "file is Missing" Somehow, I no longer have any pictures on one hard drive from 2016, that I had backed up, as if they never were backed up on that drive. On the second hard drive (and newest from last year-Seagate 5TB)), pictures that I had worked with are now missing. The dates are greyed out, and the message is that the pictures can be found on the hard drive in my "quickbooks"accounting folder. Slowly, more and more of my files are greying out, and disappearing into that file, without my having moved any of them, and with that, are no longer existent! Yes, I looked into the quickbooks file, and there are no picture files.
When I have tried to import pictures into lightroom from my memory card, the bar on the top right fills to 3/4 of the way as if it is uploading pictures, and then stalls there. Looking at "current imports", the number remains on "0", and the program freezes. I have to "x" out of the uploading to get the program back. I have had no problem what so ever uploading the pictures onto iphoto, so I don't think it's a problem with the memory cards.
Show me a screen capture of the part where it says the message says your photos can be found in the quickbooks folder.
Also, please explain why your Lightroom is pointing to the backups instead of the originals.
Somehow, this photo was imported into the quickbooks folder, or was moved there after you imported it. I assume this was done by mistake. In any event, you need to first find the photo in your operating system, and then in the Lightroom dialog box above click on Locate and then navigate to the actual location of the photo and then select it and click on OK (or YES or whatever the affirmative is).
You cannot tell Lightroom to back up to two drives at import. You can direct Lightroom make 1 backup. The other copy that Lightroom makes is your "original" and that is what the Lightroom catalog uses.
