I find it hard to believe that Bridge is corrupting files, as it's job isn't to actually open files, but merely to preview and pass them on to other programs.
When you say "it only happens when in Bridge", what do you mean? Can you give a bit more detail. Maybe walk us through what's happening?
Do you have Canon DPP? Do the files still appear corrupt in DPP or in Mac Finder (or whatever it is you use on the Mac to look quickly at images)?
If it's just corruption within Bridge, then it may be that it's the preview cache which is corrupt, not the images themselves. You can purge the Bridge cache from the Edit > Preferences > Cache menu, but this won't actually fix the underlying corruption problem, which could be hardware related.
Thanks for responding. What happens is I highlight a large group of files then click on open with Bridge or in Bridge I go to the subdirectory with the files. All the files are in a filmstrip on the left side of the screen. All of a sudden the file that I am viewing becomes corrupt (that is it turns into multiple horizontal lines of colors. Then I can watch as it happens to one file after another. I would compare it to when you quickly view film strips that were just uploaded and the initial thumbnail is blurry and then slowly all the thumbnails get clear as they process. But here they appear to already be fine thumbnails but then turn into the files with horizontal lines or sometimes just 30% or so so of the pic is visible and the rest is white or gray. When I try to open it the file cannot be opened because it is corrupt. It happens to both the RAW and the JPG file (I shoot in Raw+JPG). The first day it happened to about 200 of the 1200 files. So I was able to process the 1000 good ones in Raw convertor and create JPGs with no trouble. The next day I open all the files in Bridge again to see if the bad ones are good now and files I had already opened and were perfectly fine in RAW converter start to corrupt one after another like the ones did the day before. So I doubt it is the card or hardware it only happens in Bridge. Bridge must have the capability to do something to the files. It isnt making XMF files so thats not it, it is actually corrupting the RAW and JPG files. Have you ever heard of that. I found another forum with what sounded like the same issue to someone who had a Canon: http://forums.adobe.com/thread/645620
But this happened to Windows and I use MAC.....but I do use a 7D like them. I still wonder if Bridge just doesnt work well with Canon 7Ds or something like that. The above thread never found a solution. Maybe someone from Adobe has heard of this from others and discovered a reason or solution. Until then I cant trust Adobe products at all....which really sucks after how much it cost me, but whole shoots lost is worse, I guess.
Terry, you never answered my question: have you tried to open the files in other programs, like DPP or other image viewers, to see if they are really corrupt, or just appear corrupt in Bridge?
No, I have never heard of Bridge corrupting files. Bridge opens proprietary Raw files with Camera Raw (hosted either in Bridge or Photoshop), but CR does not write to them, instead writing metadata to either XMP sidecar files (or CR database, if selected in CR preferences). If converting to DNG, CR writes metadata to the DNG but should not write to raw image data. JPEGs are opened/written with Photoshop. So, I can't see why you think it's Bridge causing problems.
Bridge creates a thumbnail and large preview images in its cache for every file it browses. If not set to use embedded images, it uses Camera Raw to create high quality versions of Raw files, and (I assume) it can generate JPEG thumbnails itself. Theses image previews are stored in a hidden cache folder for future browsing use. If these previews become corrupt, it may appear that the files themselves are corrupt. The procedure described by Omke should reset the database and cache, if they have become bad.
You haven't said where these images are stored. Is it on an internal or external drive? It still sounds like a hardware issue to me. It certainly doesn't sound like a Bridge problem.
Yammer....yes I have opened the files in other programs and it is corrupt in all of them. I even emailed a file to another computer and it looked the same....horizontal colored lines. They went bad while on my Mac hard drive. I feared a virus so I bought Norton antivirus and scanned the whole computer....but nothing was found. I feared having Bridge on my computer after my wife told me under her profile it kept bouncing on the bottom strip as if it wanted to do something. I couldnt afford to risk losing even more filres after two days of files corrupting so I uninstalled photoshop and bridge. So not sure where to go from here. If anyone has any ideas I am open to it. I think I might back up all photos (which I need to do anyways) then reinstall photoshop and bridge and see if it happens again.
You may be right, but I'm not totally convinced. Just because the images appear corrupt in Bridge, it doesn't mean that Bridge is doing the corrupting, if you see what I mean. And if you rest easy, now that Bridge has gone, you may find that the problem remains if there is a computer fault at the root of it.
But, I have very little experience with Macs, so I can't really advise what to do. If it was a PC, I'd run a disk & memory diagnostic program. You have already mentioned anti-virus and backups.
Reinstall without using the cleaner tool has no use. first deactivate PS and use the official uninstaller for Adobe, then find and read the Adobe Cleaner tool (Google for it)
Follow the instructions and then first use Apple Disk Utility (appl./utilities) and run check and repair permissions.
Then install PS again.
Always make a back up after cheking the files are good.
Can you report back how you import the images, it would not be the first time a false card reader or cable causes corruption.
Yammer....yes I have opened the files in other programs and it is corrupt in all of them.
Other users that have seen similar "corruption" usually narrowed the problem down to either a bad card reader, bad cables, or a bad drive. If you have alternate ways to read in info to computer try this.
