Using Lightroom Version 4.2 RC on a Windows 7 64bit. When I import pictures (Nikon RAW) into Lightroom they appear fine but as I switch into Develop Module lines appear in my pictures. Some are white and some are black Sometimes 1 line and other times 2 lines. Has anyone else experienced this?

Marc, that sounds like some kind of corruption. Can we see one?

If the raw images are sound, my advice would be to purge the ACR cache.

Hi Victoria, John,

Thanks for the quick responses!

I don’t have an image with me right now (I’m at the office) but I’ll add some screenshots tonight. I have a doubt though because, the NEF files (Nikon RAW) were on a PC that had never rendered RAW files so no jpeg or thumbnail was ever created from the RAW file itself. I kept the RAW files as a backup to my in-camera produced JPEGs because I knew that one day I would find the time to learn LR (which I did this past month) and start working on my pics!

When I imported the pictures into LR 4.2RC the pictures were fine. As soon as I opened the Develop Module for 1 of my files, that picture and a whole bunch of others suddenly had lines appear through them...

The lines aren’t really pure white or black; they actually have tiny specs of colour. I will add a few screenshots for when I get home tonight... I will also try and use the Nikon software that came with my camera to see if it also has problems rendering my RAW files

I'm no LR expert and I’m also new to RAW files but it would be weird corruption that would allow you to open a file but then have line going through it but the rest of the picture is fine, no? (Then again I have no idea how NEF files are built...)
In order to purge the ACR file, I assume I can shut down LR and delete the file itself and restart?

Thank you both for your time!

Marc

Here's a typical picture with a line appearing across it. Please don’t judge its artistic merit; I just wanted to show the lines... I have yet to open the RAW files using different software to see if it’s constant. That will be my next step...

Here's a bit of freaky news... If I take an original NEF file (one that has never been opened in Lr) and open it with Nikon's Capture NX2, the picture is fine. If I then open the same NEF in Lr 4.2, a line appears in the picture.

Now here's the kicker, if I take the same file after having done NX2 (picture is fine) then Lr 4.2 (line appears) and now go back to NX2, the line now appears in NX2...

Conclusion Lr is corrupting my NEF files!

I need to test this in Lr 4.1 to see how it goes... more to come...

Hi Marc,

I assume you are working with NEF directly in LR (not converting to DNG etc). If you are not turn on "Write date or time changes into proprietary raw files" in Lightroom's catalog settings dialog (it is off by default). Then the chance of Lightroom actually corrupting your original NEF is zero. Lightroom never modifies the original proprietary raw files.

Lightroom might handle the file corruption issues differently from other applications. That might explain the difference. We would like to get a copy of one of your problematic files. Do you see the last modified date of the original file changed because of working in LR?

Do you have your catalog settings configured to write date/time changes into the original file? That's the only way Lightroom even touches the file, and even then it is unlikely to cause this. But its worth checking - and if you have that set, then turn it off and see if the problem goes away. That will at least offer a clue.

Finally, which Nikon model are you shooting with?

Thanks,
Becky

Follow up on Simon and Becky's feedback...

My understanding was exactly as you describe it, Lightroom DOESN’T modify the RAW file so I spent quite a bit of time reading up about this and talking to Lr users and all agreed that the huge advantage of the Lr approach is that your original remains untouched... Of course this has me even more perplexed...

My current hypothesis is hardware... Due to size constraints, my catalog is currently on an external disk (1Tb Iomega Prestige 2.5” portable hard drive). It isn’t a pro-grade drive but it has been up to the task and faithful up to this point... Don’t really know how to approach the troubleshooting of this yet but I will start looking into it... I can make a copy of the corrupt file available (as well as a copy of the non-corrupt one) if someone has tools that can analyse them... They are big though, 72MB each

I’m currently playing with a Nikon D800E so the NEF files are huge and the drive is relatively slow but still, speed (or lack thereof) doesn’t equate to corrupted files... The drive works, I can still access all my old JPEGs, my music, and tons of other stuff...

Thanks for the info about the “write date or time changes into proprietary raw files” I didn’t know about this but no, I haven’t checked that box...

Has anyone ever seen this type of situation where limitations in the hardware were selectively corrupting files?

Thanks for the insight and help Becky, Simon!

I am now getting the same kind of corruption in my D800e images. But I typically open them in NX2 first.

I get the exact same kind of line(s). Always straight thru the image and some times multiple lines thru them. Once I save the image in JPG the line is there too.

So I am wondering if it is my computer. Because my laptop does not show them from the nef or when saving as JPG. But the JPG's saved form my desktop have the line clearly on my laptop too. I was wondering if the line is really there or not and thought maybe my monitor was having an issue. But clearly when I save a JPG on my desktop the line exists and is present on my image regardless of display device. Ipad, Iphone, Laptop (PC) and Desktop (PC).

Did you ever figure this out?

Sorry for the tardy reply Martin! I'd like to give you some constructive news but no, I never did find a solution to this problem... I'm still thinking that I was related to the initial hardware I copied the raw images to... luckily I kept my memory cards from when I had this issue and the files on these cards appear to be in good shape... other than that, I’m enjoying my D800E!

Marc - No worries. Thanks for the reply.

I have narrowed it down and can create the issue repeatedly. It is a bad External Drive.

My normal workflow is to MOVE (My bad - copy only from now on) my images to my external drive (which is subsequently backed up to a secondary drive.

As long as I go to my local HD or one of my SCSI drives with my image copy I am good. But as soon as I copy to the drive in question I get the same corruption.

I am going to contact Toshiba but it is probably out of warranty. I was REALLY worried it was my D800e. Thankfully it is not. My faith has been restored!

Awesome Camera that D800e!! :-)

Martin, good to hear there is a conclusion for your case.

I am having the same issue with a bunch of photos I shot at a wedding last weekend. I shoot Sony and as long as I open the raw file in Sony's software, the lines do not appear, but when I pull them up in lIghtroom 5, they appear after the photo has been loaded for a few seconds. They do not appear at first, which is weird. I keep all my files on an external hard drive, so it is interesting to see that you think that that was your problem. I'm going to try and load them straight to my laptop's internal hard drive and then load them into lightroom and see what happens.

It would be interesting to note what make of external hard drive we are all using... I have the same problem, I also use a D800, and also initially freaked out thinking it was the Nikon at fault, and then thought Adobe was to blame.

I too, by process of elimination, worked out that the problem was occurring during the file transfer from Memory card to External drive. I have also found that my images are degrading whilst they are on the drive (more lines appear each time I access the image in lightroom) and am frantically looking for a more reliable solution. I have tried defragmenting the drive to see if that helps, will update if it does. My laptop drive is out of the question as an immediate backup solution since it is loaded with CS6 Production Premium and Lightroom it is permanently on the verge of falling over, so I am looking around for alternatives...

My dodgy drive is a western digital My passport 2Tb.

I am using a 1tb my passport. What is baffling me is that my wife and shoot with the exact same model of camera and the lines only appear on images from my camera. I thought I had a work around where I could remove the image from the lightroom catalog and then rename the raw file and then re-import the image. It worked once, but then I wasn't able to get it to work again.

The drive I was having the issue with was a Toshiba 2TB external Drive. I have not had the issue reoccur with my new Seagate External Drives.

Keep in mind the drives that are in the various brand external drives could be the same. I think my drive inside the Toshiba is actually a Western Digital.

Allen Adams - Do you both use the same computer and drives? Do you both use the same method of transferring images from your cards in the exact same way? For a while I thought it was my internal CF cardreader on my PC.

Yes, I upload the images from her camera and mine to the same folder on my external hard drive and then import them into lightroom from there.
The frustrating thing about this is that it is totally random. I can go several shoots and not have a single issue, and then all of the sudden there will be several images messed up in the next shoot..

I've actually even started shooting with a new camera model since I had first posted and I still have issues. The issue is not with a certain camera, but definitely how lightroom is handling the import of files located on an external hard drive.

Hi Allen, have you tried replacing your drives? Most issues of file corruption are hardware failure, or low level driver, related.

Yes. I've gotten new 2tb ones because my 1tbs where full and am still experiencing the same issue.

Okay, so its not a thorough case study, but it is looking like the problem may be linked to western digital... I note that I have never had a problem with my Seagate drives.

Hi Marc, Martin, Allen and Tamara

Did any of you resolve this issue? I ask because I have the same problem with black lines appearing on various photos when working in Lightroom 4. It all started when I removed my photos from my Mac HD (to allow for space) and used a WD external HD (My Book Duo 2T) for storage of my photos. I transfer photos direct from my camera to the external HD. The black horizontal lines usually appear from a longer than usual loading period on Lightroom.

Could anyone please provide the best course of action?

Many thanks,

Are the lines showing in the library module or develop module?

And which LR version are you using?
