Lightroom encountered an error when reading a catalog file and needs to quit.

Since I installed Snow Leopard, I keep getting this error. LR restarts and the catalog is fine, but I leave it running and come back an hour or so later and there is the same error.
I verified the file system on my USB drive and it is fine. It is a brand new catalog that I created from exporting an old one. I've never had this issue before.
Sorry if this is a double post, I can't seem to find the original post I thought I made.

Deleting the preference file didn't resolve the issue.
I am using USB, but the enclosure I'm using is eSATA and USB. I use to use the eSATA connector, but my eSATA control is not supported by Snow Leopard. I'll try to find a Fireware enclosure to use this weekend.
I spoke with Apple support who told me I need a firmware upgrade for the hard disk. That doesn't make any sense to me.
Thanks,
/Chris

When opening my lightroom 5- It pops up Lightroom encountered an error when reading its preview Cache and needs to quit.... Can someone walk me through the steps!?

Opening my lightroom 5.. I get a message that Lightroom encountered an error when reading its preview Cacge and needs to quit.
Can someone walk me through the steps. Im dealing with MAC computer

Go to the folder containing your catalog and delete the folder with the extension .lrdata. Then start Lightroom, and it will begin creating a new cache file.

Have a problem with Lightroom 5.4. Since the program crashed yesterday it won't launch, it comes up with the message "Lightroom encountered an error when reading its preview cache and needs to quit". " Lightroom will attempt to fix this problem next time it launches". Except that it doesn't, I keep getting the same message and the program closes. Does anyone know what I can do to repair it? Can't back up, can't do anything.

There are dozens of threads in this forum that describe the fix

What to do when get error 'LR encountered an error when reading from its preview and needs to quit'?

I have Lightroom 3 Verion 3.5 and every time I open it I get he message "LR has encountered an error when reading form its preview cache and need to quit'. When I close down the computer and restart the error continues. I read on the forum that this can be fixed by deleting the entire previews folder that is next to hte Ircat file. I have done this (the file is 1.3GB) and the error has gone but how do i go about rebuilding the previews?
Have i done the right thing?
Thanks for taking the time to help me.

Jen,
Yes, you've done the right thing. Menu item:
That will rebuild your previews. If you have a lot of images in your catalogue, it can take quite a long time.

Out of the blue lighroom is saying 'error when reading its preview cache and needs to quit' every time i open it

help!

Delete all your previews, and the previews.db and rootpixels.db files, and preferably clear the acr cache.
Then select All Photographs, and go to library/previews and choose build all new standard previews. If you have a lot of images, do this overnight.

When backing up lightroom 4 catalog, get message "lightroom encountered an error when reading from its preview cache and needs to quit" this occurs during optimization stage of backup

i upgraded from lightroom 4 to lightroom 5 and installed it on a separate hard drive. Initially had no problems util my computer crashed due to the failure of the drive on which Lightroom 5 was installed. Since having my computer rectified, i am unable to use lightroom 5 getting the message "lightroom encountered an error when reading from its preview cache and needs to quit"
I can still use lightroom 4, however, i get the same message when i try to backup the catalog. This occurs during the optimisation phase of backup.
I suspect it is related to Lightroom 5 creating a catalog from the Lightroom 4 files and cannot now locate those files or that they have been corrupted.
Would appreciate any solutions / suggestions.

You need to delete your preview cache and have Lightroom rebuild it. Cache location can be found here.

Lightroom encountered an error when reading it's preview cache

I been getting this error for over 2-3 months and thought it would go away with the new version releases, i tried all the standard fixes,deleting the catalog,compacting etc. even moving it to new folder, reinstalled the software twice. The whole nine yards. IMHO, there's a problem with the software, it may be uique with differetent type of machine setup or a corrupt file in the in the catalog and the compacting doesn't fix it.
The error always happens while in the develope and crashed, has to leave the software (sometimes it just hangs the software and you have to kill the task manually). You have at least 10-15 seconds before going back in, otherwise it will still crash, a thread is still occuring from the orginal crash and still completing it's task. That's the error, annoying as heck.
My only hoping is a new version of LR comes out soon (4.0) and it goes away, otherwise, I'm going to find something else-- driving me crazy, I spend about 10-15% of my time each week getting out and back in to make go away, then can go for a day(s) sometimes and no problems. I tried recreating the problem on specific photos where I think it might be corrupt, that doesn't give any clue, there is no pattern to this at all, it happens randomly on new photos and old photos, yet i can go back to those photos again and no problems.
Any NEW ideas would be appreciated (no compact, no new catalogs, new installs, turn off various options cache preview etc. move to new folder and more.....done that etc.).

The error is exactly what's it in the title of the post, Lightroom encountered an error when reading from its preview cache and needs to quit. That's it.
I don't know what else to tell you, i wish I had more. This is all over the internet, I followed pretty much all the solutions, delete the catalog or delete the preview folders (tried both). Tinker with the cachee preferences.   Most people kill the preview folders and the catlog gets recreated and there problem is resovled, doesn't work for me.
No cloning, totally two different catalogs (not networked etc.) a good question though.
When I am refering to catalog and cache, I strictly talking about LR only, nothing outside of that or in the operating system, just LR files only, here they are:
I have a   LR catalog folder called--->   C:\Users\Mark\Documents\LightRoom Catalog\LR_Catalog
you have another folder called: LR_Catalog Previews.lrdata   (with many subfolders underneath at)
and I have LR catalog filein C:\Users\Mark\Documents\LightRoom Catalog\LR_Catalog
LR_Catalog.LRCAT
That's it, a file and a folder with many sub-folders. I'll get a screen print with error next, but it's basically what I said earlier in the beginning, you can be in develope or even the library, and error occurs in a message box, you hit ok and the application exits. On average it can happen 6-7 times with an hour and sometimes not at all, working with same the photos. Sometimes it can happen within mintues, sometimes not at all for over 2 hours. There is no specific pattern to it.

Error Launching LR 5: "Lightroom encountered an error when reading from its preview cache and..."

Error Launching LR 5: "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."
I've tried renaming my catalog.lrcat file. I've copied over my most recent backup of the catalog.lrcat and that didn't work either.

On Mac:
PS - to open the previews "folder" (a "package" is just a "special" folder) on Mac, ctrl-click and choose "Show package contents.." - same way you open any other special folder, like .app or .lrplugin..

When I tried to open Lightroom 5.4 today I got a msg that says "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 lauches". What do I do? I get the msg each ti

"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 lauches". What do I do? I get the msg each time I try to open it.

It isn't a file, it's a folder. It will have the same name as your catalog, but will have the extension data. It will be in the same folder along with your catalog. If you need to use the search feature to search for *.lrdata.

I get the following window on loading Lightroom 5.7 -
Lightroom encountered an error when reading from its preview cache and needs to quit.
Lightroom will attempt to fix this problem next time it launches.
I have tried several restarts, without success. Also reinstalled Lightroom; no joy
Any suggestions?

Using your system browser (Windows Explorer or Finder), open the folder that contains your catalog. In Windows it is in your pictures folder and then in a Lightroom folder. Inside of the Lightroom folder you will find another folder that has the extension .lrdata. It will have the same name as your catalog except for the extension. You need to delete that folder, and then start Lightroom again. Lightroom will generate a new previews folder, and you should be back in business.

Open the folder containing your catalog. In that folder you will find another folder with the extension .lrdata, and you need to delete that folder. After you do that, Lightroom should start normally and will create a new preview cache.

LRCC Error: Lightroom encountered an error when reading from its preview cache and needs to quit.

I just upgraded from LR 5.7.1 to LRCC a couple of days ago. After working with a collection of images in Lightroom CC, this message popped up: "Lightroom encountered an error when reading from its preview cache and needs to quit." What do I need to do to remedy this? Thanks!

Quit Lightroom
Then trash the preview cache. It’s in the main catalog folder.
Delete the folder with the ending Previews.lrdata
The default location for the Lightroom folder is normally Pictures/My Pictures if you did a standard installation.
Re-launch Lightroom after deleting the Previews folder.
N.B. do not touch files ending .lrcat

Ightroom 5.7 "lightroom encountered an error when reading from its preview cache and needs to quit"

I got this error message after start in Lightroom 5.7 "lightroom encountered an error when reading from its preview cache and needs to quit". It seems also catalog .lrcat disappears from disk. Also preview catalog .lrdata doesn't exists. So I try to reinstall Lightroom without success, I am still receiving the same error. How I can reset Lightroom to new catalog? I have backup of lrcat file, but I am not able to start Lightroom due to this error.

It seems solved. I have copied backup .lrcat to Lightroom data directory and I still have received error mentioned above. But when I doubleclick on .lrcat file in Explorer the catalog have been opened without problems.
