Lightroom 3 Corrupting .CR2 RAW files on import

I have never used RAW files before yesterday. About to shoot a wedding in a couple days so desperately need a fix or at least some advice for a workaround.
Here's my hardware list:
Canon 7D
SanDisk Ultra II 2 & 4 GB CF cards
Windows 7 64x
Internal card reader, not some flimsy USB thing
Lightroom 3
Problem:
After importing .CR2 RAW files using Lightroom 3, not Bridge, I found that some (not all) of the images appear to be corrupted. On the camera they look fine.
For a short moment, in Lightroom, they look fine, but then after clicking the thumbnail they instantly develop strange corruptions, like pink/yellow/opaque static.
This is not one of my photos, but the corrupted image looks just like this: http://thekuipers.org/images/IMG_2279.jpg
Used some advice and downloaded Fast Picture Viewer, which allows me to view the .CR2s in the folder I imported to, and MOST of them look fine now. Reimported to LR and now only like 8 of 200 images are corrupted. They still export to .jpg as corrupted.
I had formatted my CF cards immediately after importing, only to find the corruptions after. Using Stellar Phoenix Photo Recovery to try to reimport manually the residual data from CF cards. Will know if that works soon.

From previous posts on this forum there are several things that can cause this type of corruption on import; faulty, CF cards, card reader, cable, and RAM.
On my system it turned out to be faulty ram. Since changing my ram I have not experienced any further problems.

Corrupt CR2 RAW files

Has anyone found a fix for CR2 RAW files being corrupted? I have read all the thread postings I could google on various forums and can not seem to find any solid fix to the problem.
I purchased the Canon 400D for my trip to Asia and shot over 1500 photos, almost all in RAW. I transferred 90% of the images onto CDR and DVD media to make more room my Sandisk Extreme III 4gb card. Of the 1500+ photos, 150+ of my images remain corrupted.
I am posting this in hope that someone has found a fix.
Hardware:
Canon 400D Xti Rebel
Sandisk Extreme III 4gb
Atech Flash Technology "Pro-Gear" USB 2.0 card reader
IBM/Lenovo Z60M desktop replacement
Software:
Canon's DPP (Digital Photo Professional)
Microsoft Camera Raw Viewer (does not work with CR2)
Adobe CS2 with latest upgrades
I filled my CF card up four times during the duration of my trip.
Listed in order:
1 - 6 CDR's
2 - 1 DVD
3 - 3 CDR's
4 - straight transfer from CF card to my Z60m laptop
Of the four times I DL'ed images, the first 4 CDR's were the only folders that did not carry any corrupted files. All files were DL'ed onto a PC using my Atech card reader locally before burning.
Of all the images I took, I noticed a total of about 2 to 3 images that are shown to be corrupted when played back on my camera. I reviewed each and every file anywhere between 1 to 5 times on my camera prior to transfer and they all looked fine (maybe the camera plays back the embedded jpegs?). I would delete all images using the in camera function. I formatted the card before each fresh shoot. Originally thinking it was a CD/DVD transfer issue, that would not explain why some images from the last batch off the CF card (straight from CF card to reader to laptop) were also corrupted.
Here's my workflow (I'm new to RAW): I used Canon's DPP for a day and all the thumbnails displayed perfectly. Like CS2, I believe the software first displays the embedded jpg Thumbnails before loading the actual RAW preview. I did NOT notice any corrupted images based on the rendered thumbnails but I have not verified all my images first before making a strong claim to this.
I have not installed my copy of CS2 at this point and anxious to use Adobe Bridge, I did so the following day. After playing with some images, I began to notice some weird lost of colors in some of my thumbnail preview images. I attempted to open these files and DPP gave me a corrupt image notification. I tried it in Adobe Bridge and the images opened only to show me that either the image had part of it white, black or various colors. Some images were entirely black.
On the advice of a forum poster, I used Fastone Image viewer to see if I can save the image as jpegs and it worked but the jpeg was a smaller both in file size and dimension; not a complete lost at least. I did not recall having any image corruption with the exception of about 3 images (at most) which was witnessed on the camera itself during playback which prompted me to think that there was a bad sector on the CF card.
Notes:
- One forum poster suggested that Microsoft's RAW viewer were causing problems. Originally, I attempted to open one or two CR2 files and MS RAW viewer launched but gave me errors. I DL'ed the latest version and installed it and it will also not work on CR2's. After reading the MS page on the RAW viewer, it shows that CR2 was not supported yet. I then uninstalled the proggie after reading the posting.
- Another forum poster suggests that it is a bad card reader. I will attempt to transfer images directly from the camera going forward.
I'd hate to have this happen again but can not fathom why the problem will not reiterate itself with more RAW transfers going forward. Hopefully, someone has a good solution. Thanks. -Will

Rita,
The process for determining what is causing the files to be corrupt can be a tedious one depending on the following:
1. Can you review the images on your camera's LCD screen without problems? If not then the problem is most probably either a corrupted/faulty memory card or a faulty camera. If this is the case then your best bet at recovery (of sorts) is to use a program such as BrezzeBrowser from BreezeSys to extract the embedded jpeg versions of the corrupted RAW files from within each RAW file. Chances are, you won't manage to actually repair the corrupted RAW file but the jpegs are better than nothing.
2. If the images review ok on your camera but are corrupted when viewing on your computer and there seems to be no other problem with other files on your computer then it may be either a faulty card reader or usb/firewire cable between the card reader and the computer that is the culprit. Try the card reader with a different cable and also try a different card reader to determine the cause of the corruption.
3. If your symptoms are that you get different files corrupting over time when viewing them on your computer then the problem may be any one of either failing RAM memory, hard disk, hard disk controller or IDE/SATA hard disk cables. This is where the troubleshooting can be pretty tedious testing then eliminating each item from the list of suspicious pieces of hardware. Try the card and card reader on an altogether different computer to see if the files transfer correctly to that computer. If so then the problem lies with your computer hardware. If you haven't already done so at this stage, backup all your important data immediately (hopefully you keep backs anyway).
Hope this helps.

Preview of CR2 raw files on import window from camera

Hi
I have this problem with my Canon XTI. When I connect the camera to the computer and open the import dialog window, I can not see the previews of my CR2 raw files. But if I copy the CR2 files to he hard disk and try tho import from it, then previews are shown on the import window.
Can anybody help me?

Probably because the program is trying to write back a marker to the card as it "opens" the images for the preview and the camera won't let it.
It's not a good idea to import images directly from the camera anyway. Card readers are really cheap - and they WILL let you see the previews.

Photoshop corrupting CR2 RAW files

I opened about 80 CR2 RAW files in Photoshop to preview, tweak a few, and export as PSDs. Clicking the down arrow to see each pic, three different times I got the twirling beachball. After waiting a while I force quit PS and when I opened them again the file that was twirling became un-readable. PS says "File format module cannot parse the file." What gives? I've never seen this before on other versions of PS. I'm on Lion and am running the trial of Design Premium.

Mr D\'Errico, I think that we misunderstood each other. You are more than welcome to share your experience here. I am and have been moderator on several forums online, but, as you might have read from other's comments, I am not known to be confrontational, au contraire...
Sorry if you tool offense, I did indeed mistakenly believe you had similar issues than the OP, when you were in fact sharing previous experience.
But, I really did not mean anything bad, and am flabbergasted to the extend on which you took my posts as being confrontational, as they were intended as being helpful, as most of my posts are!
I genuinely tried to explain the reasoning of my mention of the Elements forum, in my second post, by explaining that several Elements users seeking for help arrive here, and we usually redirect them where users with more experience with that product hang out. I did not mean at all to wave you off of this place, as, everybody is welcome to hang out everywhere they want in the forums, share experience/knowledge, like you did in your first post; I just tried to explain why I made the elements forum notice in the first place.
As for my remark about optical disks, sorry, but I will stand on it: (besides my typo :"small" when I meant "slow" ): it would be quite slow to read them directly in ACR, or to write the XMP (if writing is allowed) compared to reading/writing them from the Hard drive, especially, as you mention rightfully, when some optical drives can have issues, thanks again for reporting it.
Now, can we please get back to the problem at hand? If you want, you can contact me by private message, I'd really want to settle this misunderstanding. I'll stop the coffee if you do, ok?
Thanks for the vote of confidence, Noel, Dag, Trevor and Jeff!

Lightroom ignores some RAW files on import

I know that variations of this have been discussed in a number of threads, but here is one more scenario:
In a folder I have several RAW files. In the same folder I also have some PSD versions of the same photos (these have been converted from the corresponding RAW files with ACR, enhanced further in Photoshop and then saved back as PSD files, all this before I started using Lightroom). The RAW and PSD versions have the same name except for the extension (in this case .CR2 and .PSD).
When importing from a folder with such a mix of RAW and PSD files, Lightroom always ignores the RAW version of a RAW/PSD pair (the PSD version is imported, the RAW version is not, I can see this is happing already in the Import Preview)! This seems to happen regardless if the state of the "Ignore Suspected Duplicates" flag.
After a (partial) import like this, if I try to import only the missing RAW file(s), Lightroom tells me that "The following photos will not be imported because they are already present in the library...". The list of files shows that Lightroom is actually trying to reimport the Photoshop (PSD) files even if I this time actually selected only the missing RAW (CR2) files!
I guess this must be an error of some sorts?
Jørgen Johanson

This is a well-known and discussed problem: if you have RAW plus PSD only the PSD will be imported. A workaround is to move the files that didn't import into a separate folder and import from there.

Lightroom 4 missing RAW files on import

After upgrading from lightroom 3 I'm having a problem importing my raw files. Most of the time Lightoom 4 will only recognize some of my .CR2 files and only the JPGS of the rest of them. The weird thing is that it's not my card reader. When I access the card through finder I can see all of my files. It's only in Lightroom that I can't access all the files.
It's very random about which CR2s will and will not be recognized at any give time. Sometimes it's one day only of a shoot, sometimes it's completely random photos spread across different days. I always shoot RAW+JPEG on a Canon 60D. As of now I just keep plugging and unplugging my card until all the RAWs show up for an import but this is annoying and time consuming. Anybody know what's going on?

Suggest you try the 4.1RC (available here: http://labs.adobe.com/downloads/lightroom4-1.html) as there were some bugs in this area which were fixed in the RC.

Lightroom 4 corrupting Nikon D800 RAW files on import

Has anyone experienced Lightroom 4 corrupting Nikon D800 RAW files on import?

How do you know they aren’t corrupted before you import, or the old one wasn’t already corrupted and you just regenerated the preview and could then see the corruption where what you saw, before was from the preview cache and not the current image?
Is the corruption a problem with the Previews or does LR actually choke on the file and say it is unreadable or show you a gray thumbnail or pixilation starts halfway down the photo.
Can you prove the files were intact coming off the card and only are corrupted after importing into LR? Can you get to the originals on the card, still?

Importing cr2 raw files won't work on ios 6 when it worked fine on ios5. Anyone have a solution?

I have been importing cr2 raw files to my iPad using ios 5 but importing cr2 raw files won't work on ios 6. Sees files in camera but when import stops it fails with an exclamation mark in red circle. Anyone have a solution?

Don't know if you care anymore or it applies, but I was able to get things working but it took drastic measures.
I had to do a full system reset and update by doing the following:
- Make note of all your settings in your system and apps especially accounts and forget about in app data that's only on your iPad and not in a cloud service because it will be gone after this
- Connect iPad to Mac and startup iTunes
- Hold down Home and Power buttons simultaneously for about 8 sec until the screen turns black
- Release the Power button but continue holding the Home button until there's a popup on your screen which indicates it's in recovery mode
- Follow the instructions to recover your iPad but recover it to factory state, not recover from a backup
- Reinstall all your apps and content
- Reconnect to all your services on your system and apps
I could not restore from a backup since it brought back my bad data too. It also didn't restore my music and no matter what I tried it wouldn't put my music onto my iPad. Had to start clean.
It appears over time that the system gets dirty and there's lots of bad data that can't get resolved. This is especially true if some of your apps have crashed a bunch.

After Effects CS6: Canon .CR2 RAW files not recognized as acceptable files for import?

HI Folks,
I'm trying to import as I've seen on tutorials, my RAW files from my Canon 5D3 .CR2 files. I can open them in PS and LR5….and I'd seen examples of folks opening them with AE CS6 standalone, but it doesn't seem to recognize mine.
Any thoughts? Is there something I need to update, or flag or change?
I'm on a mac, OSX 10.7.5
AE verson: 11.0.4.2
This is what my import screen looks like:
Thanks in advance,
C

I read through those linked pages, but they didn't give me any solution.
After nosing around through a LOT of sites on Adobe's site (why aren't pages dated, took forever to find the most up to date or pertinent pages)…I found this one that was slightly related, but worked for me.
http://helpx.adobe.com/bridge/kb/acr-84-bridge-cs6-metadata.html
I had to download this zip, and manually place the plugin as directed, and now, After Effects CS6 will recognize my CR2 raw files from my canon 5D3.
Thank you for the help, it led me in the right direction, but the link above was the actual solution I found that worked!!

Corrupt/Non Viewable Canon Xs .CR2 Raw files

Hi All,
I am having issues with my importing/viewing my Canon Xs .CR2 Raw files. I import them into Aperture and they do not show up correctly. I get either a black or a green and magenta static with lines for an image. I am currently running both the latest Aperture Version (3.1.1) and Digital Camera RAW (3.5.0). I have been searching for three days and cannot find a solution to this problem. I have found a few other people having issues as well. Here are some snippets/links from/to these posts:
http://discussions.apple.com/thread.jspa?threadID=2667652&start=0&tstart=0
“The latest Aperture 3.1.1 update breaks Canon's "Medium RAW" compatibility; Aperture used to be able to read the "Medium RAW" CR2 files before this update, but not anymore. Also, updating to the latest "Digital Camera RAW 3.5.0" does not solve the issue.”
If anyone can please help, it would be greatly appreciated.
Thanks,
Jeff

>in which respect is ACR4.4.1 so much better than it's predecessors?

LR corrupting my Raw Files

I've read the other discussions but haven't really seen an answer yet and the typical responses don't seem to apply to my situation. Here is my situation:
I'm am getting corrupted RAW files after importing into LR. Typically this is blamed on Hardware issues but I don't think that is the case for me. I am getting 1 corrupt file per 100 or so imported. I've had it happen using different CF cards. And the file doesn't seem to be corrupt on transfering to my hard drive. I'm using a Canon 40D. Using Lightroom 3.2 64bit. I shoot in RAW. Here is my work flow.
I import the photos to my external hard drive via the camera.
I then back up the originals before importing into Lightroom by burning them to back up discs.
I then import them into Lightroom from their location.
Upon initial look everything is fine but when you actually select an image and the preview is fully rendered you can see the corrupt image. Usually a white rectangle in the bottom right side the image. Sometimes you get the yellow and pink streaking in that same area as well.
In trying to open the original file from my hard drive using just my basic Canon Digital Photo Proffesional after it was imported into LR it also states that the image is corrupted.
Now if I get out my back up disc and copy that image to my desktop and open it in Canon Digital Photo Proffesional it opens it without problem. There is no corruption. So the file that I backed up from my hardrive shows no corruption. I think the original file is fine.
I then copied the image from my desktop to the original folder on my external hardrive overwriting it. The image in lightroom is now fine. There is no corruption.
Process of elimination leads me to believe that the corruption happens on importing into Lightroom. It isn't my cards (different cards same problem). It isn't my external hardrive as the file copied from that drive is fine. It seems random especially being that I can overwrite the file with the same file and then it is fine.
I really hope this problem is sovled quickly. This to me is a BIG deal. Any other ideas?

Thanks, I'll think I'll go ahead and invest in a new hard drive.
I know about the jpeg preview thing. The corruption doesn't show until you attempt until it renders the image at full size pulling from the raw. I know it isn't a display thing as exporting the raw to a jpeg still shows the corruption. The file is corrupted and attempting to open it with other programs shows the corruption. It seems odd that the corruption doesn't happen when being placed on the hard drive from my camera as my back up shows no corruption. The corruption is happening at a later point. Would an image start out fine on a hard drive and then end up corrupting apart from any program changing it?

CR2 raw files

My wife swears blind that when she used to drag a Canon CR2 raw file from iPhoto 08 on to the desktop she used to get a .cr2 file on the desktop, whereas now she gets a jpeg. Is this right? Is there any way to get a raw file if dragged on to the desktop? I know that export will get a raw file on the desktop but she says that's the Windows way of doing things she just wants to drag it out as a raw.
Regards,
Steve

Steve:
Welcome to the Apple Discussions. Your wife is right but don't admit it. Just tried it with iPhoto 6 and the original CR2 file is created when dragged from the thumbnail to the desktop. I won't tell if you don't.
Suggest that feature at http://www.apple.com/feedback/iphoto.html.
Do you Twango?
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
I've created an Automator workflow application (requires Tiger), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. It's compatible with iPhoto 08 libraries. iPhoto does not have to be closed to run the application, just idle. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.

every new released update of Lr from v 5.2 changed somethin in my Windows 7 Professional settings. I am stucked. Can somebody help me please? Many thanks. Andrej

Hi Jim,
yes after I imported my .cr2 raw files into new catalog it started to work. Windows 7 still does not recognize them but I can edit them as you said within the Lr5.6 and then export them into .psd or .dng files...as needed.
I bought Lr5 only because I got present - my new camera Cannon 70D and because my older Photoshop CS5.5 raw plugin does not recognize. cr2 files.
Many thanks for your help.
Andrej.

Why can't I download Canon S100 CR2 RAW files into PSE 10?

I am using PSE 10 with a Canon S100 camera. I am successful in downloading all of my jpeg files and RAW CR2 files from my older Canon Rebel, but not with the Canon S100 CR2 Raw files.
When first downloading from the Canon S100 camera into PSE 10 and later doing them manually, I receive the following messages: Nothing imported...files are not supported file types or alread in catalog. File damaged or in a format that cannot be included in the Elements Organizer.
These problems files, by the way, were automatically added to my Window's My Pictures catalog and are perfectly fine.

Thank you for the info. It worked great, once I was
able to get around a second problem that prevented updating
from within the PSE 10 application (error U41M1C212). That
problem was solved by disabling the MS Virtual WiFi Miniport
Adapter (located in the Network and Sharing Center control
panel). It just goes to show me once again, how complex
computer apps are and how much we all have to rely on each
other to get anything to work properly (frustratingly
enough, since the companies we paid good money to for
their problematic software are not very helpful). Thanks
again.

Try opening a CR2 directly from a folder by right-clicking

Canon 5D CR2 RAW Files Have Visible Artifacts

There's a digital dithering pattern that's clearly visible on CR2 RAW files even with no adjustments in Aperture. Here are two example screenshots from Photoshop. The first is an 800 ISO image and the second is a 50 ISO image. I shoot RAW + JPEG.
In the first, the JPEG from the camera, zoomed at 400% (top) and the equivalent JPG export at quality "12" (lossless) from the RAW image in Aperture with no adjustments (bottom). This is just the RAW, exported to JPEG at lossless 8 bit, same area at 400%. I experimented with 16-bit TIFF and PSD exports as well and the dithering pattern is the same:
http://www.pipsqueak.com/imagehosting/ApertureJPGBug.jpg
In the second, I took the original RAW, converted it to DNG format (I have to in order to use Adobe Camera Raw on CS 1) and imported into Photoshop using ACR "camera default" settings. I show that image at 12.5% at the very top and a detail in a window at 400% in the middle of the stack. The bottom image was created by bringing the RAW into Aperture and, without making any adjustments, exporting it as a 16-bit Photoshop file.
I picked the blue area because it's easy to see the dithering pattern in a solid color. But it's there across the image.
This is not just a high ISO or highly adjusted image problem. This is an EVERY image problem, at least with Canon 5D CR2 files.
http://www.pipsqueak.com/imagehosting/ApertureExport_Bug02.jpg
I've taken the same file, processed it using Adobe Camera RAW in Photoshop, exported it as a 16-bit PSD file and brought that into Aperture. Exports from that file are flawless. So I conclude that this has to do with the way that the OS is converting RAWs from the Canon 5D (or CR2s generally).
Can this be a priority to fix? If Aperture can't export high quality images, its other truly admirable features will be for naught.

Ian wrote a really good description of what RAW files are:
http://discussions.apple.com/thread.jspa?messageID=1303439&#1303439
Since the RAW file is encoding the chip information, and the two 1D2 and 1Ds2 cameras use different chips (they do, don't they?), then it's conceivable that they could have different results in Aperture.
On the other hand, I thought that CR2 files had the same underlying file structure, so it's strange that they encode differently.
Might it be possible to take some kind of test image with both cameras that is basically identical and has some areas that are dark? It would be interesting to compile a list of those cameras that have conversion issues and those that don't. I know the Canon 5D conversion is not so good, and that there's an Olympus problem (although I don't remember the camera). On the other hand, there are a number of Nikon users who seem pretty pleased with their conversions.
