CR2 files corrupted
« on: July 31, 2014, 09:57:03 AM »
Hi,

I'm really hoping someone can help, as I'm getting desperate now after spending days trying to recover some photos from a recently holiday to Italy, and I'm almost pulling my hair out!

I have an EOS 600D, and a SanDisk Extreme 16GB SDHD card. I inadvertently changed the camera format to RAW format (must have done this before the trip, and I wanted the top JPEG quality + RAW). When I emptied the card onto the PC, I just transferred the JPEG files (incorrectly assuming everything I wanted was there) and then formatted the SD soon after this.

I soon realised what I'd done, and managed to recover a load of CR2 files with the correct dates and times taken on (using Stellar recovery software), but it seems as though they are all corrupt. The file sizes look like other CR2's I've had before - 22 - 24Mb.

I've tried lots of different software to try and extract the preview JPEG's out of the CR2 files, but none of them let me. Now I can't even see the files on the SD card when I use recovery software - I have a feeling the card has been written to. I've not taken any more photos on it, but after formatting from the camera it creates 2 folders on the card.

My question is - is there a way I can recover these CR2 files? Am I able to post one on here for someone to look at to try and help me? They all seem to be the correct file size which is majorly frustrating, as there must be some useful data in them somewhere!

Thanks in anticipation of some help on this!

Some recovery software will not recover cr2 files properly.  I had to try several, and finally bought Image Rescue 4.  Since then,  I've heard that there is some good software that's free, but there may still be some that doesn't work for cr2 files.

Often, the issue with corrupted files is that the card reader has issues, so trying a different card reader is another possible solution.

As long as you have not overwritten the files, they are still there and safe.

You might want to let your image software copy the files from the card, good editing software will copy all, both jpeg and raw.

A similar disaster happened to me just the day before yesterday, for the first time I have to day. The first recovery (usually very good) software I tried was unsuccessful and the cr2 files just contained garbage data - sd cards seem to need different handling than hard disks.

I then succeeded with "Raise Data Recovery" for fat, after a deep scan of the sd card it managed to save all cr2 files intact. If you didn't write to the card after formatting it might very well for you the same way. Good luck!

Edit: Unlike other first-time posters writing about data recovery software, this post is not spam :->

You can try Rescue pro deluxe. It comes free with some SANDISK cards.

LOL, I guess we all can vividly imagine like *that* felt :-> ... this is one of the reasons I'd really rather have a dual-slot 5d3 than a single-slot 6d, Murphy's Law dictates that the card will wait to fail until a critical moment :-o
