Corrupted CR2 files repairable?

[norbi]

Thanks, Phil!

One thing I overlooked last time is that aside from those 3 jpgs, there is also a block of 16-bit uncompressed image data (the dimensions are 362x234). This block is pointed to by the third top-level IFD. So I fixed-up a couple offsets, made the 3rd IFD the only IFD (pointed to by offset at position 4). Then I just changed extension to tiff and most programs were able to open it. The resulting image itself is very dark (almost black), but so is the same image extracted from another valid CR2, so it seems the purpose of this block is something other than preview. I used auto-adjustment in FastStone to make it brighter. Colors may be wrong (because of the damage), but I'm not sure. The result is attached.

Hi phil, i also have a corrupted file problem,

ive taken 900 photos but half of them are corrupted with no preview and an error in exiftool.
I believe it happened when i was taking raw images too fast and i couldnt write properly.

This is one of the images if you could please take a look at them thank you

hopefully the JPEG can be extracted but i dont know how

johnnyyn,
I downloaded your image and unfortunately, it's full of 0xFF bytes, so there is nothing to save whatsoever  , not a single bit of information. Maybe other damaged images are different, but only you can tell.

I confirm Norbi's conclusions.
