I'm attempting to help a friend recover some jpegs which spontaneously became corrupt (and of course no backups were made :Q). One day seemingly random photos would show up with varying amounts of gray covering the photo (ex. http://www.cgsecurity.org/mars2_small.jpg ). Some thumbnails are intact. Unfortunately, there are hundreds of corrupt jpeg files.
Some picture show no thumbnail and refuse to open with any software. The files of this kind still report a size of several megabytes.
I have opened them with a hex editor and they do contain data; they lack an EXIF marker, however. Photoshop give an error stating "JPEG does not contain valid marker"
Is anyone familiar with any recovery options? I have tried a handful of automated recovery programs with no success.
From some reading I've done, it seems that "data carving" might do the trick. PhotoRec is able to do this, but I can't find some comprehensive instructions on how to utilize it.
Any help or link with information is greatly appreciated.
Thanks 🙂
