Recovering DNG, but corrupt

#1 Post by barbo » 20 Oct 2016, 11:18

Hello. First of all, WOW!! Impresive work with the software and also with the forum!
I have a problem with a .DNG files, deleted by a software bug. I have been trying to recover the files with diferent software, but always same result. I can see the preview, but the complete image its corrupt. Im pretty sure the files are not corrupt in the SD card, because if I recover older (and OK) images, i receive the same kind of archive with the correct preview and corrupt image. Also all the corrupt images have a pattern in pack of six images. Look the image attached with some images and you can see the pattern. https://drive.google.com/file/d/0B1Svr- ... sp=sharing

Also i was able to extract the JPG embebed in the DNG, and view the exif info of the dng, but the RAW image always still corrupt.
I tryed selecting the TIFF options, and using the photorec_win v7.0

I have upload a couple images if you want/can take a look deeper.

Normal image from the camera: https://drive.google.com/file/d/0B1Svr- ... sp=sharing

Corrupt image after recovering: https://drive.google.com/file/d/0B1Svr- ... sp=sharing


If i can fix it or modify any parameter in the aplication to recover it correctly it will be great.

Thanks!

All the pictures are corrupted with the same pattern. First one, small part corrupt, next one the corrupt part its bigger, and next bigger, until the Sixth picture, who is almost corrupt completly. Then, new pack of six images starting for with a picture with a small part corrupt and finishing with another almost corrupt all the picture. I didnt delete manually the pictures, but I think the software do something wrong and delete the folder 100MEDIA and created 101MEDIA. (the android app to control the camera crash during the sesion). Also say, if I recover pictures who was ok inside the deleted 100MEDIA folder, i have the same problem, and i know that pictures was ok, becouse i was able to copy to my computer last day after the session.
Thanks

Can you put a small memory card in the camera, format the card, take 3 pictures, run testdisk, Advanced, Image Creation
Compress (ie. zip) the image.dd file and share it via google drive or similar
I will check if the files are stored in contiguous blocks or not.
