My MBP is also getting very warm easily. But HD is deeply tested with TechToolPro, Diskwarrior en DiskUtlity and all looks great
Occurs only after files are edited, not each one but a lot of them get theb corrupted.

Almost certainly the images /are/ corrupt before import, either on the original media, or during transfer.

You don't say how you imported these. You don't say what format these files are (raw or JPEG). You don't supply an unimported original so we can see for ourselves. Please update this thread with these details. Try yousendit for sharing images.

But Lightroom doesn't just read the embedded preview that most other apps do when opening image files. It reads the data and metadata thoroughly, and so is more likely to find actual image corruption when the embedded preview is sound.

In the many years people have been using Lightroom, I have never seen a case where corruption like this was caused by simply importing an image. Every single time it has been the media, the transfer or something else unrelated. It is just that Lightroom is more likely to uncover the hidden corruption.

If the originals are corrupted beyond repair, you can try to extract the previews with EXIFTool. At least you will have a camera-prepared JPEG version that way.

Where do the images appear corrupted?
Is it just the thumbnails, or do the files fail to open?

John and Chris,

My answers:
Original images were Full HiRes Raw. (Canon 5D MKII with the latest firmware update from Canon).
Not only thumbnails were corrupted. The images fail to open also.
I think they get corrupted after extensive retouching in PSD 5, before they were OK (now I am not sure)

Sorry I deleted those files in the mean time: impossible to send it.
TIP: is a very nice way of sending big files! Try it!

As solution I deleted a lot of fonts, give my entire system a clean update and installed a new OS and reinstalled PSD again

In the mean time Adobe Support team provide a solution for future occurrences:
To re-create the preferences files for Photoshop, start the application while holding down Command+Option+Shift.
Then, click Yes to the message, "Delete the Adobe Photoshop Settings file?"

It seems solved my problem, I will be testing this weekend.

Thanks you both for your help.
