LRC suggesting images are corrupted...

[Grafenauer]

I have imported a large number of files from a football game into LR Classic and a few have shown up as being corrupted.  I have opened them in Bridge and in Photoshop and they're fine and I've saved them in Photoshop and they are still fine so it doesn't appear to be the card itself.  And I've used two different readers so I don't think it's the reader.  I deleted the "corrupted" files from LRC and copied them into a file on my desktop to re-import.  Some came in fine and others are still indicated as "corrupted".  I could keep doing this until they are all in LRC but this seems a tad odd.  

Anyone else experiencing this or have an explanation?

Thanks

What type of readers are you using? Are they direct USB plug in style or are you using a cable to connect them to your computer (try a different cable if you are)?

What happens if you Copy them from the card to a folder on your drive and then import them?

What happens if you connect the camera directly to your computer and either Copy them to a folder or import into LR directly?

I have not experienced this.

I have a Lexar Professional and a Delkin both of which are connected via the USB. I never connect my camera to import photos. As I mentioned, I copied the so-called corrupted files to my desktop and was able to import them into LR as uncorrupted files but some took more than one try.

[Just Shoot Me]

But do you use a CABLE to connect these card readers?

Also just for a test. Use a Different card, snap a bunch of pictures around your home (20-100) then import them from that card using either reader. What happens.

Bridge is looking at the embedded JPG file inside every RAW file.

[Grafenauer]

Pretty sure that it has nothing to do with the readers. I can't add screen shots to this reply but LRC in Library mode is showing the file as corrupted. I exported it as a jpg and it's fine. I also edited it in Photoshop from LRC and it's fine in Photoshop. I then saved it and the psd file is fine in LRC. It's something in the Library mode that thinks the image is corrupt when it isn't for any other purpose.

[Just Shoot Me]

And I did not say it was the readers. I said Try a Different Cable, if you are using one. I also said Try a Different CARD. Please Re-Read my reply above. To post images, screen shots, in this completely Stupid forum software you have to Post a reply then use the More button, link to Edit the reply and then you get a proper Text Entry dialog window/box where you can add screen shots.

I'm not sure what other cable I would use other than the one that comes with the reader but I don't think it has anything to do with how or where the image comes from because the image is not corrupted at all. It's just LRC Library mode reporting it as corrupted. As I mentioned, I was able to edit it in Develop as well as in Photoshop. I was also able to successfully export it from Library mode. I have since shut down LRC with a backup (to run the integrity check) and re-looked at the image in question and it seems to be fine now. I'm shooting a soccer game this afternoon and will see if I experience another episode of mystery corruption that isn't.

[Just Shoot Me]

Ok so if you don't want to try some solutions to the problem I don't know what else I can suggest. If this was a Wide Spread problem, a BUG in the new release of LR, there would be many more posts about it, other than just yours. It could also be the setting for the GPU in the LR preferences. Try running your system with that option turned off.

[Grafenauer]

I imported nearly 1600 images from this game from 3 cards and this problem was random with about 30 images of which I only kept a few. I haven't changed any GPU settings in the many years I've been using LR. It's the same laptop that I've used for nearly 5 years. This just started yesterday for me so I thought it might be a recent issue.

[Just Shoot Me]

From LR CC 2015 there is a GPU setting to use the Graphic card to help process images. There was none before that. It has caused problems on some system. I'm suggesting to disable it, or change the setting for it, as a TEST. And LR Classic was just updated 2 or 3 days ago to LR 8.4.1. All the best to you.

So, I see that Just Shoot Me has given you good advice that you are being argumentave about. Ok, fare to argue, but gee, try his advise.

Here is the thing. This very issue has come up before. Images just like yours. Issue in Lightroom Classic, but not apparently in Photoshop, not in Bridge, nit in Windows File Explorer, or MAC Finder.

 Now STOP

 Before you say but...

Windows File Explorer, MAC Finder, and for that matter Bridge are not showing you the RAW  image nor a preview, they are showing the embedded JPEG

STOP

but Photoshop... Are you sure that is not defaulting due to error to the embedded JPEG

Well, three main and one occasional causes have occured in past problems as reported in the  old forum

1. Bad SD card (SD, CF, whatever)

2. Bad SD card reader

3. Bad USB cable

4. Other connected USB  device causing input/output and/or IRQ conflicts (would more likely not get to use the card reader at all)

So, humor us

Do you have another card reader

 Is your card reader hard wired or can you substitute a different USB dara cable (data, not the blasted charging cable that came with a phone)

[Grafenauer]

I wasn't trying to be argumentative. I felt I had eliminated the card and the card readers (I tried both of my readers) because when I opened the image with Photoshop directly from the card, using both readers, the image came in successfully and I was able to edit it and save it successfully. This indicated to me that the image was not corrupt on the card and that the readers were not corrupting the image on import. Also, when I viewed the image that looked corrupted in LR Library module, it looked fine and was editable in the Development module which further suggested to me that the card was not corrupt and that the readers did not corrupt it on import.

This happens to me from time to time. As I use topaz for noise reduction, I can send the image to Topaz and it is accepted - nothing wrong with it - goofy LRC problem.

[GoldingD]

I am thinking several dirty words about this new web site.

Ok, went back and looked at the two ( is it 2?) sample images

 Both in a Library module correct?

 And one showing a  corrupt filmstrip but proper loop view?

 Exit, close Lightroom. Go and delete your Library previews. Then have Lightroom recreate them (as a result of restarting a Lightroom. Possible corrupt previews?

[Grafenauer]

Thanks. I'll try this if it happens again. When I closed Lightroom, I forced a backup which runs an integrity check. I didn't get any messages but when I reopened Lightroom, all was as expected. Nothing looked out of the ordinary so perhaps it was something to do with the preview just for that image. Or some other random thing.

[GoldingD]

Some online experts do not like running the integrity check when closing Lightroom. This is because that involves a backup after the check, and if the integrity check foules up, then the backup is fouled up. Instead , change how Lightroom opens. Change it from launching the catalog previously opened, to inquiring what catalog to open. when you launch Lightroom, you can then choose via a dialog screen to run an integrity check. Apparently safer that way.

[GoldingD]

And, possible GPU driver failure. Please post your system information as Lightroom reports it. /Help/System Information/Copy. Paste info from first line down to just past the plug-in info. Info after that just gobblygook as far as many care.

I shot another game yesterday and imported around 1600 shots (3 cameras, 5 cards) and had a few more alleged corrupted images from two cards. So today I did more testing. I imported the images from each card from each of my two readers..same result but not always with the same images. One reader has a fix cable and I don't have an appropriate one as a replacement for the other reader. So I imported them directly from one of my cameras using the cord that is supplied with the camera (1DX). Same result. I deleted the LR preview file and when I opened everything up, all was fine. I then deleted all the photos and tried again from the camera. Same result (apparent corruption but can make changes in Develop module) but with a different image this time. I am attaching images including system info (once I get a chance to edit this post).

[GoldingD]

Ok, for clarity and efficiency, I am reposting your system information, not as an undesired attachment, but as pasted data in a reply. The prefered method of sharing such data is by actually pasting it into a reply. Now you may need to edit your reply to get the tools required (this new web site sucks) but one of the helpful ones is that “Insert Code/Edit sample” button currently third from right. looks like </>. Click on it, paste in the system information, and you get that inside a nice box

I notice that you are running MAC OS 10.14.6. Have you installed the supplemental update. I do not suspect it is your issue, but it does solve some MAC issues that royally foul up Photo Merge

see http://osxdaily.com/2019/08/26/new-supplemental-update-for-macos-mojave-10-14-6-released/

As this is a MAC, absolutly nothing you can do about GPU drivers. All hail Apple.

Display 1920x1080, using GPU  acceleration will probably not be very helpful, hopefully will not hurt. More useful 4K and beyond.

Nothing in your plug-ins stands out as buggy. Mind you, unless your Facebook page is commercial, that Facebook plug-in is useless.

Also, when posting photos or screenshots, use the Photis button, currentlysecond from right, looks like a landscape photo, to place them in a reply. We overlook attachments, but images clearly in our face work better.
