Lightroom: Metadata write errors
Hello all,
Having constant issues with both Mac Lightroom 5 and Lightroom CC (2015.7) being unable to write metadata to sidecar XMP for my RAW files. I will sync my files, then Command-S to make sure all changes have been saved, before exporting.
Preferences are set to “Automatically write changes into XMP”. Files are on a networked server. Permissions on folders are always correct (Read and Write), however when Lightroom writes XMP, I get the following error message, usually with random files, but not all: “Could not write metadata. Unknown file I/O error.” If I sync the metadata (on the same files) using Bridge (using copy and paste), I get no errors. I don’t want to use Bridge, but that does show me the problem is linked to LR.
Was previously using Lightroom 5, and read that the error was a common LR5 issue, so initially went back to Lightroom 4. LR4 worked! Did not have the issue using LR4, but realized to my horror, after exporting multiple files, that all the edits I made in LR5 were incompatible with LR4 (for example, clone and heal tools were completely off their marks). Aargh! My fault for not checking backward compatibility. So, finally gave in to the cloud subscription thing (Lightroom CC (2015.7). But, issue is no better. Any suggestions greatly appreciated!
Thanks!
Sara

However here, I have never gotten an error message... After saving metadata, it will just reshow the badge gain - or in the smart collection I use for it, it will disappear for a second, then reappear.
One thing I have done to fix these lately (discovered about a couple weeks ago) was to delete all snapshots and reset the image - and just start over. That fixes it here. So I'm thinking it must be some errant develop instruction that might be causing this.
