Yet another corrupted file story - Any hope ?

[theseb]

Hello,

I have noticed that a small portion of my NEF files library has suddenly become corrupted. These were photos taken from a Nikon D700, and I use a Mac.
I have put in this folder (https://www.dropbox.com/sh/o7ou32jkjpjn6f3/AAB04XEheaz2rux4Ohp3wgMga?dl=0) 3 pictures : one is fine, the second one partially corrupted, and the last one unreadable.

Any chance there is a way to fix the damaged files ?
Thanks !!

The last file is entirely binary zeros, so nothing can be done with this.  The end of the raw data in the second one is similarly binary zeros.  From the second one you may recover a full-sized JPEG preview (exiftool -jpgfromraw -b -w _jfr.jpg FILE), but the missing raw data is not recoverable.

Hi Phil,

Thanks a lot for your answer and all your hard work helping people on this forum.
Does anyone know how these files get suddenly corrupted and zero-ed out ? Is there any way to prevent it from happening ? I'm sort of scared about my other pics now !

Almost always a hardware failure.  Check your card reader, cables and RAM.
