Has anyone experienced Lightroom 4 corrupting Nikon D800 RAW files on import?
Thanks so much, no, importing from 32 GB San Disc Extreme via card reader into LR. I've read some of the other "issues" but none match this exactly. It's happened about four times and tonight suddenly a two year old Nikon D300 image got corrupted during import. It wasn't being imported, was already in the catalogue.
Hi Jim, thanks, no, I'm familiar with that phenomenon. In this case, the file is actually being ruined. At first I thought it was just the LR preview but checked the RAW file and it was also damaged. I can watch it during import and looks fine, then suddenly goes corrupted. Have used LR for five years without such an issue.
How do you know they aren’t corrupted before you import, or the old one wasn’t already corrupted and you just regenerated the preview and could then see the corruption where what you saw, before was from the preview cache and not the current image?
Is the corruption a problem with the Previews or does LR actually choke on the file and say it is unreadable or show you a gray thumbnail or pixilation starts halfway down the photo.
Can you prove the files were intact coming off the card and only are corrupted after importing into LR? Can you get to the originals on the card, still?
The Preview looking ok is just the camera-embedded JPG which is near the beginning of the file, before the RAW data, and the corrupted view is the raw data attempting to be interpreted, so this doesn’t mean the file was corrupted during import, it could have already been corrupted on the card or coming off the card.
Thanks very much. Files are okay on card and they were backed up before importing to LR. The older file has been fine and been used in various collections, exported, etc. in PS for two years so this corruption is absolutely new. I thought the corruption was just the previews but LR does say unreadable and shows multi colored banding/pixelation on the photo preview AND now in the actual file. All are backed up and can be restored but this is frightening to wonder what else is/has been corrupted. All this since installing LR 4.
