CR2 Corrupt File Questions

OK... I recently had a failure of the OS on my NAS and one of my other backups. I was able to strip the data off my NAS's hardrive to recover all my archived RAWs. I got a new NAS and put them all back on the network drive. So, I thought all was good. I was wrong.

My problem is that 90 percent of them seem to be corrupt now. Lightroom can't read the CR2s (cannot work with this file). I tried copying some of them locally, but I get the same messages in Lightroom. I will be distraught if I lost all these RAW files.

Does anyone know what is going on with these files? Is there anything I can do to recover the data now?

Also, it seems like CR2 files are pretty brittle. Should I be converting everything to DNG or doing something in my workflow to make these files a bit more rock solid?

Thanks everyone.

Are they corrupt on your backups as well? If the NAS drive failed I would only recover the files if no other copy existed. Pulling them off the backups is safer.

Also, is it only LR that has the issue? How about DPP? Also corrupt there? CR2 files are no more fragile than any other file. They can take damage but if some key locations are hit, like the file header, all bets are off. Same with jpeg, tiff, dng, pretty much any file.


Not sure why, but call me JJ.

I do not have DDP on my computer. The Windows 8 RAW codec can't pull up the image either. The newer RAWs on my desktop are functioning like normal in Lightroom and Win8.

I find it odd that none of my music of videos were impacted. Just my RAW files.

Hmm.. I'm thinking something more global. I can't imagine that every raw file got corrupted in the same manner. Too much of a coincidence. Maybe something with LR? or some codec? Just guessing.

I'm hoping it is something along those lines. That sounds more fixable. Before the NAS crashed, I did change Lightroom to start adding the separate XML file for edits. I wonder if that has something to do with it.

Questions:
- Why is your OS on your NAS?
- Why wasn't your NAS backed up?

If you get file corruption no data format is going to help much. I suspect jpeg would be as good as anything. I keep everything important as CR2/NEF, plus DNG, plus high res jpeg, on three different disks in three different locations.

I believe Roger (OP) said his NAS operating system failed and therefore couldn't function normally.

The old NAS was a DLink 323 (linux). The OS failed, but the hardrives were RAIDed and still had all the data on them. I used LinuxReader to pull all the data from the files onto my Windows 7 desktop. It seemed to work for everything but my RAW files.

Also, all my JPegs are stored on three different machines and online. I did not lose any memories, I just lost the RAW files associated with those memories incase I want to go back and edit those memories. I am not as redundant on my RAWs because of the sheer size of the storage space I need. I have a 2 method back up for those, but one (my desktop) outright failed (HDD went bad at the same time ny NAS died) and the other was the NAS.
