Random "Lightroom encountered an error when reading from its preview cache" message
I am getting this error randomly. When I restart LR everything is fine, until I get this error again. This problem has recently started occurring frequently when I exit LR during the backup. Sometimes it occurs when LR is just sitting there and I ma not interacting with it. I have not seen a pattern as to when I get the error.
My system drive is a SSD with the LR catalog and preview cache are on another SSD used exclusively for LR. My main data drive is RAID 0 with images and catalog backup to a NAS. I'm running LR 5.5 64-bit on Windows 7.
I've tried deleting and rebuilding the cache which takes a while at I have 42,000 images consuming almost 6 Tb but this does not seem to have any effect.
While this is not a show stopped, it is annoying as every time the problem occurs I need to exit LR and restart.
Any help will be appreciated.
Could be the Previews.lrdata file which stores the previews? How about moving it out of it's existing location and see if you still get the error.

"Lightroom encountered and error when reading from its preview cache and needs to quit"
I keep receiving this error every time I open LR, "Lightroom encountered and error when reading from its preview cache and needs to quit" and the app won't open. It said LR would try and fix this error next time I opened it but the error remains. I tried uninstalled and installing the app and the error remains.
Any Ideas here? Is there another app that may be telling it where to look for the cache and it no longer there? I was using a ramdisk for a bit but ditched it. Not sure if that has something to do with it but it seems suspect.
Your thoughts?

Use Windows Explorer to open the folder containing your catalog. The normal location is Pictures\Lightroom. Locate a folder with the extension .lrdata and delete that folder. Then you should be able to start Lightroom again, and Lightroom will begin building and new previews folder. Do not delete anything else.

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..

I recently updated my HP laptop's OS from WIndows8 to WIndows8.1. When I went attempted to open Lightroom5 I got the following message:
"Lightroom encountered an error when reading from its preview cache and needs to quit. "
"Lightroom will attempt to fix the problem the next time it launches"
Every time I relaunch I get the same message. I'd like to understand what might be causing the problem so I can remedy and get back to my photo editing. Any clue as to how to fix this problem would be greatly appreciated.

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.

You don't delete a file, you have to delete a folder. Is that what you did?
If you deleted the folder specified above, and you still get the message, then it's the wrong folder. Use your operating system's search function and find ALL folders on ALL disks whose name ends with Previews.LRDATA, delete each one found, and then try opening Lightroom. -

"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.

Every time I open lightroom I get a pop up message saying "Lightroom encountered an error when reading from its preview cache and needs to quit" and it closes. Ive already tried reinstalling, nothing seems to work. Help please!
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.
