Same issue here with LR4

What "same issue"?
Corrupted Raw or streaks gone after adjusting exposure?

Corrupted RAWs after importing to LR4. Previously viewed in Canon's ZoomEX and there was no issue. After importing to LR4 no longer able to open in DPP either.

EDIT: forgot to add, I tried playing with them in Develop module, but unable to get rid of the issue, tried playing with exposure and few other sliders.

One of them in LR4

Hmmm. That's not good.
Never experienced something like that, so cannot help much. I'd suspect the HDD though.

Got the images backupped? If so: Can you post an affected and an unaffected copy online somewhere?

Thanks for the links.

I just finished my shoot, I'll check them out soon.

This time I'll try to import my files directly using LR4. I was always using EOS Utilities to import files before, but I want to try something different this time.

It might be my HDD, it might also be my memory card (I recentely got a new one). It might also be LR4. I will try to do my workflow slowly and make sure every file is ok.

I have seen that same corruption from both a failing CF card and a failing/failed hard drive. The CF card did it inconsistently, it seemed to have the most trouble with bursts and videos. The failing hard drive did it randomly to some images in past shoots, more in more recently written files.

If its a hard drive, be warned that this can be silent corruption and you wont notice until you open the raw in develop mode or discard all your previews and rerender them. Unless it happens to corrupt the previews, then youd notice.

Some images had the embedded jpg corrupt but not the raw itself, others had the raw corrupted and the embedded jpg ok.

Thanks very much for that post. That's actually what happend here. The baby boy image that is corrupted is actually a shoot from few weeks ago that was sitting on my HDD. I only recentely got LR4, so I decided to import this folder to LR4 and just saw one after another images being corrupted just after importing to LR4. So I panicked and quickly removed the folder from LR4, but the images stayed corrupted.

This is actually quite worring, because I suspect you might be right with the HDD. I recentely had a report from one of the utilities programmes I use that my HDD developed 2 bad sectors, but the stuff over there was remapped and this was even before this folder was created on my HDD. Since then no problems with HDD, but maybe, as you say, this is just happening behind the scene.

Damn looks like I need some more HDDs and sadly this is not a good time to be after HDDs, as the price went up last year after the floods in Thailand and stayed up since then.

Thanks a bunch, this got me thinking.

I posted this same problem some years back and never got an answer. Here is the difference with my issue that makes it all different...

So I had images that worked just fine after downloading for sometime and then suddenly became corrupt. Recently I found backups of those images prior to corruption. I had originally used LR and then stopped for a long time (having nothing to do with this issue). Recently I installed LR4 and while I had the catalog open so I can see the corrupt images I copied the good images over them. As expected the thumbnails updated and I was able to open the images without issue BUT HERE IS THE INTERESTING PART... images that originally were originally fine suddenly got the funky colors and patterns just like the poster shows. Right in front of my eyes LR rendered good thumbnails for the corrected files and then screwed up other images in the same directory. What the hell!! So, the only common thread here seems to be LR but why would it create this 'moving corruption'.

Oh and for the record the LR4 install is on a new machine with an entirely new database so I'm not importing any errors or garbage from way back when.

Discuss.

It's not the HDD. I have had the same issue with a series of images on several drives and the only common thread seems to be Lightroom (though different machines, versions of LR and databases)

Read my previous post.

Well, those of us who don't see the problem can't give much of a response!

You might log into one or more of the Lightroom Users forums, and maybe file a "Bug Report" with Adobe? See if one of the Experts has some input/feedback?

I'm not convinced and I still suspect my HDD. Recentely I found same kind of corruption on few of my old photos which never went through LR. I found them using Canon's DPP. The folders were from 2009 and 2010 and I'm 100% sure they were OK back in the days. None of those photos were imported into Lightroom ever.

I still haven't sorted out my HDD situation, so I can't even re-format my HDD and see if it'd help. I need to buy 3 HDDs first in order to sort out my situation, sadly the bill for that would be around £200 and I don't have any spare money at the moment.

I experienced the exact same issue yesterday when importing about 18gb of raw files from 2 different 16GB Sandisk cards (Extreme 30 amd 45MB/s) into LR4 from an external drive. The images are fine on the camera and when viewed directly off the card in my laptop's reader.

I deleted the folders in LR4 and the external drive. I then copied them over again from the cards onto the laptop's drive and imported into LR4 and the issue is gone.

In my case it was def the external drive. I'll prob defrag that drive before I copy anymore files to it again.

Sounds like a HDD issue to me.

LR initially shows you the jpg preview embedded in the CR2, then it renders the raw. Might be the preview is okay, the raw data isn't.

Agree

I m having the same problem since I switched from Mac to PC. I think its an LR4 and Win7 issue. I think that the problem occurs when LR renders its preview. I can open the images in PS CS6 without problems.
When I delete the file and import it again, the image is good. So I dont think its a problem on my cf card.

I just played arround a bit and here is what I found out:

1. copy files from CF card to desktop
2. import files to LR4 but dont move, just add
3. render 1:1 previews
4. some files look weird and corrupt.
5. open them in PS CS6 the files are still corrupt (I thought otherwise, but I was wrong)

If I duplicate them, they open perfectly in PS CS6 and in Lightroom 4 aswell.
The very interesting part now is, if I open the previously broken RAW, its working too.
By copying the corrupt file, I was able to open the copy and the original without any problems.

Very weird behaviour.

What I also discovered, the files get broken totally random. I did steps 1-3 5 times, and everytime I do it, I get different results. Sometimes no files at all, sometimes 5 (out of 350).

Canon DPP also says the file is corrupted. But when I create a copy, I m able to open the copy. And if I then try to open the courrupted one, it opens perfectly fine.

Maybe its an HDD cache issue?
