Do you have a backup catalog that you could use?
Yeah, but it's about 30 hours old, which means everything done yesterday that wasn't written to the files will be lost.... Hopefully not too much wasn't written, but what's going to keep LR from doing this AGAIN?
OH, and the LATEST WONDER.............
While synchronizing the .dng files, LR hung with the following popup:
Lightroom encountered an error when reading from its preview cache and needs to quit.
Lightroom will attempt to fix this problem the next time it launches.....
Jeez, what's next?
It sounds like your preview cache got corrupted when you had your system crash while LR was running. Delete the previews (folder named <something>previews.lrdata next to your catalogue) and relaunch LR. Tell it to rebuild your previews and let it run overnight or however long it takes to finish the job.
Yeah........ Um, NOT a great answer.. I'm HOPING for a fix that DOESN'T involve making the system unavailable and
unusable for DAYS. 'Cause the last time I had to rebuild previews that's what it took....... We're talking Lightroom here.
Sorry, mate, but it's the best answer I have.
Me too. I just don't like it! I'm still hoping SOMEBODY out there has a better answer than the brute-force and massive-ignorance,
Up 'til now I've thought V3 was at least usable. But this tells me there's a big problem in there...
Well, I blew away the catalog and started over. It took a "while", but it appears to be rebuilt. And, for the moment at least until the next time LR crashes the system, it appears to be working......
I am curious, how long had you been operating LR3 when this occurred?
How many images are in your catalog?
I started using LR3 when beta2 came out. Never had a problem. I installed the production version a
week or two after it became available. So, it's been on the system a couple weeks or so. As far as
I can tell, when things crashed, I wasn't doing anything particularly heavy, just my version of "normal"
editing....... Except it crashed..... TWICE....... Of the, "push a button, nothing happens, then a second
later the BSOD"
The catalog I was working with has about 42000 images in it, around 38,000 .dng, and the rest .psd or
I got the message after importing 55 .tif files I had scanned and didn't see previews for.
When I selected one and went into the Develop module, I was able to see the preview - which appeared in the Library module afterwards.
I repeated this for all 55 images; however when I exited LR3.3, while the catalog was optimizing and backing up, I got the error.
Opening LR again showed blank previews ONLY FOR THE NEWLY IMPORTED IMAGES. Everything else was fine.
There clearly was a problem in the preview creation process, which I repeated this morning (the bar doesn't move), but I wonder why the preview isn't saved after being generated by the Develop module.
I'm going to follow the advice given regarding the deletion of the preview cache, however this is something that should be looked at (debugged). It's a waste of time and I'm not the only one who's been affected.
OS X 10.6.6, LR3.3
For me this problem just came out of the blue when going to develop mode. Every time I now restart LR I get the error message "error when reading from its preview cache & needs to quit". The faulting preview shows, but the others in the strip are blank. Yesterday I was editing the same set om import images without problems. Following the advice on deleting previews, would it not just be enough to delete all previews with yesterdays date (when I did the import)? The previews are organized in nonsense catalog names, but I can see the first 5 or so in each catalog bearing yesterday's date. Has anyone tried deleting just these and then restaring LR 3.3 (W7)?
I don't think it would do you any harm to try. If after deleting them, LR still has trouble, you wouldn't be in any worse shape than you are now. At that point, you could just blow the entire folder away and let LR rebuild it, taking however long that will take.
Easy fix! I ran a search for all lrprev files, deleted those created during the last 10 minutes, and then restarted Lightroom. Everything works fine! Actually I think it was only one preview that caused the problem, since I got the error message everytime I tried to view this picture, and then it began to appear when starting Lightroom, i.e. no way around.
Thanks for sharing your solution with us.
it worked!! thanks!
Im running a mac, can someone explain to me how to search all preview files and delete the ones from the last 10 minutes????????
I am a Windows user, but the method I’d use is the same as this, where instead of Finder, I’d use Explorer:
Use Finder, or whatever search-by-filename facility your computer has, to find all the files on your computer with a .lrprev extension. They should all be in folders a few levels under the folder where your LR catalog resides, if you know how to restrict the search to only that folder and below.
Sort the search results by file-modified date-time with newest on top. This may require a details view of some sort.
Highlight the search results with the date-time range you want to delete and delete those files using whatever keypress or menu option is used to delete files.
If your LR is crashing when you start it up, and you didn’t get a corrupt-preview message at some point just prior, then it is likely some other issue that removing the recent previews won’t help. The usual advice is to remove the preferences file in case it has become corrupted. The preference file is the com.adobe.Lightroom.plist file, located in the username/Library/Preferences folder.
