what I did recently was cleaning the MacBook Pro with CleanMyMac 3 software.
There was also some update of the LR some days ago.
NEF files were OK before.
That can be a symptom of a pending disk failure. Make sure your backups are good!
I learned more about when NEF files are corrupted.
I have my photos stored on QNAP NAS. My LR catalogue is stored on MacBook Pro (2016, High Sierra). Access to my photos on NAS is done via VPN afp connection.
When I try to develop NEF files from my Nikon D850 the picture gets corrupted as shown on the picture above. Interesting is, that other photos stored at the same NAS of formats like iPhone jpg, Leica RWL or NEF files from older Nikons work without any problem. Also JPEG files created by D850 are OK. Size of D850 NEFs is more than 50MB.
The same file corruption I experience also when I open the NAS located photo in Photoshop Camera Raw.
Curious is, that if I download the NEF file via web interface (QNAP QTS 4.3.4.0435) and import downloaded NEF to LR or PS the file is not corrupted and everything works as it should. But if I copy the NEF file from NAS to MacBook in Finder, copied file is as well corrupted.
There must be something what corrupts the file on the way from NAS to MacBook Pro. Sounds also, that problem is not in LR but in apple file transfer system.
Could somebody help me to solve this problem?
Thank you very much,
Change the network protocol to SMB.
This is a recurring problem when the Apple AFP protocol is used. Your files are not corrupted. It is the network protocol that is being used.
Hi, thank you for the advice. You are rigth, the original files are not corrupted. They apear corrupted after transfer from NAS ro MB.
I tried smb protocol, but result is the same - the NEF file dispalied in Finder looks corrupted. On NAS I set smb 3.0.
I'm having this issue only with files on the NAS. When I try to add a folder from the NAS to the catalogue, the dialogue appears, then LR Classic freezes. I have various catalogues, same issue.
MacBook Pro, Synology 218+, connected with cifs.
Importing from USB hard drive works fine.
Thanks for any suggestions.
