HELP!!! Corrupted Files ARW sony A7R

[Giancarlo Bianchi]

Hello,

 

I just recently went on a trip to Thailand, and took a small PC for making backup of the cards,

and new memory sticks.

The problem is that my first card (which I did have formatted because I had 3 backups) is corrupted,

the size of the files were the same as of the card, but now they seem corrupted and the computer

recognize the ARW files, they will show as blank.

Is there a way to fix the ARW files or extract the embedded JPGs?

 

I searched many forums and tried different programs, but none that does what I am looking for.

 

any help or recommendation will be truly appreciated.

 

Giancarlo Bianchi.

Ciao Giancarlo,

 

I usually use "Data Rescue 3", now version 4 is available. Sometimes a deep scan could help even when the card has been formatted afterwards.

 

Regards,

Marcel

Thank you very much, will trie that.

 

I hace tried Wondershare and Disk Warrior with no luck.

Is there any way to extract the embedded jpgs in the arw?

embedded JPGs in a7rii ARW only 1616 х 1080 btw

Does the replay function show the raw or the embedded jpg?

I'll give another vote for Data Rescue.

It's the only Mac software I know of that can rescue (most) of the files from a formatted disk (depending upon how much has been written to it since formatted).

It did, the thing is. That I felt safe having 3 backups, and now it seems that the files are corrupted.

The size of the files is there, but somehow my Mac wont detect it like image files.

I have tried to rescue the information from the original card, but it was written over.

What I would like to know, is if there is a program that could checksum the files I have and "reencode" for proper reading.

I know I am asking for a miracle, but I cant think of any other option.

Thanks, will try with that one.

Like I wrote earlier, I felt safe because I had 3 backups, so I used again the card.

Have tried with 4 programs with no luck, they just show the latest card. Hope to have better luck with data rescue.

I ask myself have the replys worked while shooting. And the files go dead while copying to the backup.

[Giancarlo Bianchi]

I could see the files working alright on camera, so it is some kind of transfer error.

Although, I did all 3 backups directly from the card, and they all have the same files corrupted.

[Giancarlo Bianchi]

Tried Data Rescue 4, no luck retrieving the files, did a deep search and nothing.

Can anyone advice anything else?

A program to try to restructure the files that I have?

What are you reading the files with on the Mac?

[addicted2light]

It's a long shot, but if you're comfortable with the command line you might try dcraw (it is available for every major operating system):

 

DCRaw

 

If you're on a Mac (and possibly even on Linux) try something along these lines, running the following command in the same folder where the pictures are (maybe copy them first on an hard drive). This will take quite a bit of time, dcraw is not exactly a speed demon.

 

 

for filename in *.ARW ; do dcraw -H 0 -w -o 4 -q 3 -6 -T "$filename" ; done

 

Good luck!

What are you reading the files with on the Mac?

FIle system does not recognize as pictures, Neither Lightroom or Photoshop I also tried with Image data converter 4.

with no luck. Do you have any suggestions? Please tell me you do, I am really desperate, and dont want to loose

the information on that card.

You have files on a SD Card? You can copy them to you Mac? But they are not processed by any software, probably because they are corrupt.

 

I suggest you copy one of these files to Dropbox or similar and perhaps someone here will take a look and see if they contain any useful data.

Sorry but no luck with:

 

dcraw, uFraw, Photoshop CS6, RawTherapee, RPP64, Preview, DNGconverter

 

I think you will have better luck using some kind of recovery software directly on the SD card.

 

ExifUntrasher or Rescue pro are the first that come to my mind.

The file is all 1's, so no useful data to be recovered.

 

It could be possible that the file system is corrupt, pointing to un-used space on the card, and that the photos are still on the card ... and repairing the file system might make them recoverable. But you need to google a bit to find a tool you are comfortable with.

If you can read it in your camera, plug the card in your camera and use a cable to connect to your PC for the download.

Plug the card in your cents and use a cable to connect and download to your PC.

I could also sent through wifi... the problem is that as I did 3 independent backups I formatted and wrote over the card,

just when I got back home, I noticed the data was corrupted, not the same computer I had on my trip, unfortunately,
