  • Are you ever disappointed with your photos? Do you get frustrated when you’re editing because you’ve been told to move certain sliders, but never been told WHY? Do you wish you could transform your photos without having to spend hours in front of the computer? In my new book, Adobe Lightroom CC - Edit Like a Pro, you’ll learn:
    • how to to analyze a photo like a pro, saving you hours of frustration.
    • WHY you might want to move specific sliders, instead of just following recipes.
    • what the sliders are doing behind the scenes.
    • how to use sliders together, instead of in isolation, so you can get the optimal result
    The book is based on the cloud-native Lightroom CC desktop and mobile apps, but the principles also apply to Lightroom 6 and Lightroom Classic. The sliders are arranged into slightly different panels, but there's an included PDF that shows you where to find them in Lightroom Classic/6.

I have experienced this error since LR 3.0, and on several different Windows versions, storages and even on OS High Sierra on Mac.

Anyone got a clue why this is happening?

This is data corruption. The cause of it is unknown without more information.
The basic questions are when does this occur? After you have edited the images, during import, after import....

I don’t really know.
I ‘ve been testing a lot some years ago, without any conclusion.
My best shot would be it occurs when opening the image from grid view. I have not found any link to actually editing the photo.
It happened both to jpeg’s and NEF.

If the problem is internal to Lr, then this likely is a video card problem.
Otherwise, the data is corrupted before Lr gets uses it. In the library module, Lr uses built in previews of the file, and previously generated previews.
The develop module uses the actual raw data of the image (from a simple perspective, there actually is a series of file caches involved to increase performance).

So was the file always this way? When you compare the image file to your backup, are they the same at a bit level?

I’ve Steen this on different Windows PC’s and finally also on my iMac. The iMac even got new RAM to try to sort this out.
Code:

This could be, but still I have experienced the photos being edited in LR Developers module, all good. Went back to the to-be-corrupted photo selvrealisering mintes later, opening it for more developing, and Boom! It’s cortuoted.

The backup seems fine, and when swapping the files it seems to be fine.
How do I check at a bit level?

Thank you for all your answers.
Still I would like to know how I can prevent such errors in the future? I have several of these - far too many to not try to sort it out.

I don't know if it's possible to prevent file corruption. However, it is possible to discover it in an early stage with the mentioned tooling.
To minimize the chance on file corruption you should use good quality hard disc's and replace them after a few years.

I know. My current disk on the NAS is 2 years now, and is not too busy (private usage).

Do you have trouble finding the corrupted images?
When you do, it is possible to use the (free) DNG converter from Adobe to trace them.
Can you explain this?
You suggest to convert all files to DNG?

I checked this image (top of thread) and if I get it right, LR do not write to NEF files.
The HDD do not report any sector/HW fault.
Then, what is causing this?

Yes, Lightroom is non-destructive. All edits are saved in the database as instructions. The original file is not touched so the cause of the corruption must be outside of Lightroom.

Sector/HW faults are not the only cause for file corruption. A virus is also possible for instance but in most situations it's some kind of hardware problem.

I am experiencing a very similar problem with images imported via LR on my IPAD. My workflow is to import images from the SDCARD to LR on my IPAD then let them synchronize to LR Classic CC on my PC.

When the images sync and download to Lightroom Classic CC on my PC, some are being corrupted. The file corruption is clearly in the downloaded files because it is present when I access the image in the develop module and also when I export the original NEF and view it in another program (Photoshop or ON1).

This is only happening with a few images and appears to have started in March and has continued into April. This is only happening with files synced from the cloud.

All of my Adobe software is up to date (according to Help). My IPAD software is up to date at 4.2.1

The file corruption is not present on my IPAD or in the "cloud" stored images when accessed via Lightroom CC. If I download the original NEF image from the cloud via Lightroom CC there is no corruption.

Hi cknight819, welcome to the forum!

In Classic, can I please get you to go to Help menu > System Info just to confirm the version number? Sometimes the CC app says it's up to date when it's not. The reason I ask is there was a very similar sounding bug fixed a while back. It's possible it's resurfaced in a different way though.

This is a good discussion but makes me think it would be useful to know to check the integrity of the file on the card in case there is a problem with the camera or the card. I had a quick look but couldn't find any external tool that could check the image files on a card or directory. Does anyone know of one?

I would doubt that there is a problem with the integrity of the file on the card because it transferred to ipad photos then to IPAD Lightroom then to the cloud correctly.

The corruption is present solely in the file synchronized from the cloud to Lightroom Classic CC. This was visible both in Lightroom Classic CC and when viewing the downloaded file with other software (ON1 and Photoshop). When I dowloaded the original file from the cloud via Lightroom CC there was no corruption.

This process would tend to isolate the problem to the cloud synchronization process within Lightroom Classic CC.

The date range on affected images seems to be from 3-08-19 to 4-16-18 which could indicate this is a transient problem associated with some update.

I will report this occurrence to Adobe but at this time I am not able to reproduce it.
