corrupt in Lightroom only????

My last 2 imports have had many corrupt files. I'm pretty sure it is not the card because they are only corrupt in Lightroom. However I have put the card aside for now. I can open it in Irfanview, Photo Gallery, the thumbnail is fine, everything but Lightroom is fine. Any thoughts? I have never had only one program think it is corrupt. It has always been an all or nothing deal. I know others have posted problems, but never heard the solution.

I just went back, ACR didnt have a problem with them, but now it is the same as Lightroom.

Example...

In Library module or Develop module? ACR definitely opened and edited them ok? The other programs may have just been looking at the embedded jpeg.

Every view in Lightroom is like this. The library, the thumbnail at the bottom tray, the preview window top left, and the large one you edit on.

If the jpg is built off the raw, would it not be corrupt as well?

I am thinking now it just might be the card gone bad.

I can't tell from what you posted here -- are these .CR2 previews?

And, when you say they worked at first with ACR and then went bad, do you mean you first opened them in ACR, or viewed them first with Bridge and they were good, but then went bad?

Just asking, because as Victoria pointed out, the first thing you see in ACR and Lightroom is a preview from the jpeg, but Lightroom quickly converts it to a new preview from the Raw file. And, if you open it in ACR you also generate a fresh preview. I'm not sure how quickly the Bridge browser generates a fresh preview without opening in ACR, but the other browsers you mention are not Raw converters, right? If they are just browsing they would only "see" the imbedded jpeg.

Problems with cards do indeed happen, as do problems with transferring the images from the card.

Try some tests and see if this repeats itself. Try different cards and card readers if it does. And, maybe install DPP to see how it reacts to these images.

Yes CR2's. I rarely use bridge. When I saw them turn this way in Lightroom I opened Photoshop, then "open.." wich will open them in ACR. I looked at a few and they were fine. I go back now and they are the same as above. I may not have waited long enough for the preview to flip from the jpeg to the raw preview in ACR.

I have not had a shoot for a bit so I have not imported anything. But tomarrow I have some time and will be doing some tests. I think my card is still under warrenty so B&H will be getting a call if that is the problem. Luckly they are just some personal stuff from an outdoor movie party we went to and not a customers job.

The use of the jpg embedded in RAW is primarily for the camera to display when you ask it to review captured images on the LCD. Other apps such as bridge and lightroom build their own from the RAW data and so far as I know, without reference to the embedded jpg.

You may be able to use Michael Tapes 'Instant Raw from Jpeg' to pull out the embedded jpeg, if that's ok.

And don't just look at the card - card reader or cable is another likely candidate, although there are all sorts of hardware issues that can corrupt files.

I understand . But the camera does not take 2 images. It takes a raw then quickly makes a small jpeg from the raw. So the jpg should be the same as the raw, corrupt or not. That is my point of the question.---- and now that I am typing it in, and thinking the process through... I realize the jpg is made before the image even gets to the card.

Correct, and so the problem could be with the card/reader/download corrupting the Raw data without touching the jpeg. But such analysis is hard to tell without Raw analysis software.

Multiple tests with different cards/readers/connecti​ons a lot of times at least shed light on where the problem is happening.

I thought I had time today to do some tests. But it will have to wait now Maybe monday.

Strangely, this issue still exist in Lightroom 3.2. I've been using Lightroom since version 1.0 and I encounter the same issue on all the versions. Do think it is an hardware issue, since it happens on my internal harddisk, external harddisk and NAS.

Anyone have a fix for this issue?

Thanks in advance.

Example...

I have the same exact problem using SANDISK 16MB/S EXTREME 16GB, Windows 7 PC,
This is the first time I had this problem after my first corporate shoot with senior executives. I've used RAW+JPG, the JPGs are fine. Viewing the CR2 in Picasa 3 was fine. The previews of the CR2 were also fine until LR did little thinking and the corrupted images came up. In my MACBook Pro the CR2 in LR looked fine.

My HD has about 7GB out of 1TB left. Someone previously mentioned hard drives causing this issue. I suspect that my HD is failing too. I've reimported the same corrupted images several times to the same HD, all fail. But when I import to a different HD is was ok. So corruption thankfully was in the cheaper HD and not from the expensive Camera.

Backing up HD right now.

OK. Scratch what I said previously. I just change the exposure setting on the RAW file in Lightroom and the streaks are gone. and it might be related to creating previews from the RAW files with the right exposures?

I got the hint from this forum

I'm seeing the same thing. Perhaps 1 image like this in 1500 photos. I thought it was a bad card but recently went back to a shoot from year ago shot with a different card and an image that had been fine, suddenly 'jumped' into this state. I went back to an old backup and renamed the file and imported it. It was fine. On a hunch I removed the corrupt file and re-imported it and it was also fine. Very odd. I've tried this on a few of the other 'corrupt' files but they remain corrupt after being re-imported. All very odd and worrying.

Hi Guys,

I am having the exact same problem. Was there any resolution or any idea as to what is causing this?

Thanks
