What causes 'Unexpected end-of-file' error?

[RogierBos]

Hi,

I am a photographer and an avid Lightroom user. I have two camera's (Nikon D700 and D300) and two computers, a desktop PC and a MacbookPro. Lightroom is installed on both computers.

For the last three photoshoots I have had this problem where 1 in 3 to 1 in 5 images in Lightroom on my desktop PC suddenly gives a 'Unexpected end-of-file' error. First I thought it was my camera. But then I loaded the images onto my MacbookPro and they worked fine. Then I took some images with my other camera, loaded them on to my Desktop PC, and, voila, same problem.

The problem specified: the image stops rendering a preview. A dull preview appears. At the top of the screen the message appears: "An unexpected end-of-file occurred." The histogram window stays empty and the image can not be developed.

I have browsed through this forum some looking for the cause and the fix. There are some mentions of it, but they all date back to 2007.

I run LR 2.2 on Windows XP SP2 and on a MacbookPro with OS X, version 10.5.8.

Please help me understand the cause of this problem, and help me find a fix?

Thanks,

There is a plug-in that will help validate if anything has changed with a raw file, but only if you have already computed a checksum/hash value:

I received a new D750 for Xmas.   I have taken 22 shots with it so far.  I removed the card and inserted into the internal card reader on my iMac and attempted to load those images into LR 5.7. I received the "unexpected end of file" error on 7 of those images.  Got the same results when loading the image on PSE 13.    I have loaded images from a D300s and a D800 and have never gotten this error.  based on research, looks like this is a new situation with the D750 but I still need to do more experiments to confirm this.
