I cannot open a number of D80 .raw files in my hard disk, either with Capture NX or Photoshop CS3. In both cases I get an error message, as if the files were corrupted. I don't know if this is a problem of my hard disk or of the original files. I would be grateful if someone could give me advice about how to open these files before deleting them. Some pictures were not bad and it would be a pity to loose them. Thanks
 
If you send one of them to rawfiles (at) pixelfixer.org I'll try and take a look at it for you.

If it's any help, your raw files contain a full-size basic quality JPEG when they come out of the camera, so you might be able to salvage those. You can use Pixel Fixer ( http://www.pixelfixer.org ) to extract them.

I sent you one file in several chunks to your address. I could extract the jpeg from the same files thanks to your program, so at the worst I can get the jpeg also from the others.
 
I use Photoshop CS2 to process RAW files from my D70s without a problem. I learned that the plugin Capture NX installs in not compatible with Adobe Camera RAW so I dumped the Nikon Capture plugin. I'd like to know whether you used CS2 without problems and, since upgrading to PS CS3, are suddenly unable to open RAW files.

D70S
AF-S DX ED 18-70mm f3.5-4.5 G IF
AF-S 70-300mm f4.5-5.6G IF-ED
SB-800
 
I used to use CS2 and capture nx for D70s files with no problems (the camera raw plugin, both in CS2 and CS3, is not incompatible with capture: it simply ignores any editing made in capture). Then I switched to the D80 and installed CS3 because NX could not open these damned files. But even CS3 can't, so I suspect I have damaged sectors in the HD, or that there is some problem with the camera. Unfortunately I deleted the original files from the memory card so I cannot verify this hypothesis.
 
It's very strange... I tried opening it in CS2 and it says an unexpected end-of-file was encountered, but I can't see anything wrong with the file at all. My program is able to extract all the raw data without any problems and the overall structure of the file is fine as far as I can tell. I can't explain why you can't open it, but if I were you I wouldn't delete any of those files because whatever problem they have is probably very small.

Yes, CS3 gives the same message. Is there a way to recover all the raw data or only jpeg is possible?
Thanks

If it's of any help, I use a D80 and have no trouble opening my RAW files in CS3.

I think I've found a solution, although I don't know if it'll work on all of the affected files. I ran the NEF through Pixel Fixer and was surprised to find that I was able to open the new file in CS3! Start Pixel Fixer and go into Tools-> Options and add the camera, and then Edit the camera and add a hot pixel (any location will do). Then just pretend you have a hot pixel you want fixed, and ask it to fix your files. You'll never notice the pixel that has been changed, but tell Pixel Fixer to preserve the original file just in case.

I'm still trying to work out why Pixel Fixer can read it but CS3 can't!
 
This trick seems not to work but maybe I made some mistake:
  • I added the camera D80 from a bad file, not from a good one.
  • I created a hot pixel without changing any default value (X:0 Y:0, etc.).
  • Strangely enough, when I open the file sometimes PixelFixer quits abruptly.
  • I tried this procedure for the file I sent you and another one.
Let me know if some of the above steps are incorrect.
 
Hi!

Recently I had a similar problem with some D80 files.

Since I have three SD cards and it happened with files from only one of them I suspected it was a defective/incompatible sd card.

Anyway, I could never open the raw file with Capture NX (haven't tried CS3) but I could savage the JPEG with PreviewExtractor.

The only raw converter I could use with such files was Capture One. They have a trial version in their website, you could give it a try.

Actually you are right: CS3 can open the new file. Capture NX, however, cannot. If anything else works, I will use this trick. Thanks to all you guy, and when you have time please have a look at my gallery at

That's ok, it doesn't look at raw data at that point.

That's fine, I did the same.

Ok, that definitely shouldn't happen. When/where exactly does it quit?

What you've done sounds right. Can you see any errors in Pixel Fixer's log file? It's possible it might not work on all of them, but it definitely works on the one you sent me. I'll send you a link where you can download the fixed version. The raw data actually seems to be corrupt about 93 pixels from the end of the image, but you'll never actually see that because there are extra pixels around the edge of the image that raw converters don't show you.

The total size of raw data is actually correct in the file you sent me, but it starts to contain negative values towards the end. Pixel Fixer just interprets those as zero, and keeps going. I'm surprised CS3 can't handle it, and I'm really surprised that NX has a problem with it.

You could also try copying the file back onto the camera and see if the camera itself can read it. I believe the D80 has a Retouch menu that allows you to make JPEGs from NEF files in the camera?

If you still have them, try running a copy of them through Pixel Fixer and see if it helps.

That's strange... I don't have NX so I "transplanted" the raw data from your NEF (and later, the fixed version) into a D200 NEF to see if I could open it in Capture 4.4.2. It wouldn't open the original but it opened the fixed version (although the colours were wacky because the layout of the colour-filter-array is different on the D80).

After reinstallation of Capture NX 1.0.1, the programme can open the files processed by pixelfixer. I verified that also NX 1.1 can. Thank you all guys!
