My DLink DNS 320 NAS Raid 1 fail recently with status degraded and unable to rebuilt for some unknown reasons (It just refuses to complete and will restart into an endless loop). I took out one disk to testdisk and created a image which I am am using photorec 6.14 to recover the files.

As I used the NAS for archiving purposes, I mainly store two type of files inside the NAS, the CR2 (EOS 7D Raw) and XMP files (from lightroom) plus a few other mis files like psd files. Photorec looks to be able to recover files as shown in the screenshot:



But when I copy out one CR2 files to test, Lightroom & Photoshop are not able to open them. Even when I preview them (I have installed the windows program to preview RAW files), I get a black image.

Yet I have no issues with opening the XMP files

Is there something I am doing wrongly? Please advice.

Thanks in advance.

Can you try PhotoRec 7.0-WIP and tell us if you still have the problem or not ?

Hi,

I am experiencing the same symptoms when trying to open CR2 files that have been recovered using PhotoRec 7.0-WIP

I can supply sample files if required.

Using preview, I am shown a black window with the file name (.cr2) followed by Locked in the tool bar.

File sizes are around 22mb.

Kind regards,

Andrew

Yes, please provide some unmodified file samples.

To whom may help me out!
I was moving (command-move : mac) a folder of image (CR2) files from a folder on the computer to an external hard drive, the process seemed to be complete so I ejected waited for the disk image to unmount and disconnected the hard drive - there were no alerts or warnings.
Upon reconnection of the drive the destination (new) folder was not accessible (greyed out).
I managed to force open the folder through menu>services>open only to find that during the transfer process somewhere 2 folders of images vanished.
The original folder and all contents were gone.
I used photorec and found many CR2 files INCLUDING ones from approximately the correct dates. however the file sizes are very small - less than 5mb where usually they are around 20mb and cannot be opened.
Is there any thing I am doing wrong?
I also used blacklisted_site Photo recovery - it found similar files but upon recovery the files were mostly over 100MB to 4GB and these images will not open either!!
Any help would be most appreciated
Many thanks,
Tony
