.NEF files "no data" oh no!

[steamy]

Camera Nikon D90

Was doing some aerial shots last week, all was going well and had taken ~350 so far.
Continued to take some more and glancing down every now and then for a quick check
of the preview on the LCD.
All good.
Then went to do a proper preview of the shots and was presented with a red box and a red cross through it and no data!
Went to small thumbnail preview and realised that about 150 shots had this red box/cross.

You can imagine the feeling!

Got back to hotel and transferred the files to the laptop and they are not recognised by any programs.

Thing is they are ~10mb in size so there must be some data in them.
But absolutely no EXIF data at all.

I have tried CardRescue app but it doesn't find the corrupted files.

Now I can't remember if I did a lens change at the time whilst the camera was still turned on
which happened by mistake and if this could have been the problem.
I tried doing this again to see if I can replicate the prob but it do it.

Could it be a SDHC card writing issue that I may have taken to many quick shots and not
giving the camera/card enough time to write the files...don't know!
It's a Kensington 32gb class 6 card so i would have thought it was suitable.


Any suggestions? Any rec on another program that might be able to recover the data.


cheers

Good luck

I'm on Mac so PC progs aren't suitable.

Would I be able to "yousendit" one file to you and see if your prog gets it back?
If it works then I could hassle a friend with a PC to spend some time with me to recover them all.

cheers

Just googled it and I think they do a mac version!

[Scotty72]

yeah, i just pm'd u

[Scotty72]

btw, I just checked the website

they offer a Mac version too

http://www.datarescue.com/photorescue/

$29 US one time fee.

worth every cent if your photos are priceless.

[steamy]

trying the demo version now

[steamy]

doesn't look good!
trying the professional mode and see if that makes any diff.

no thumbnails were rendered...so no image!

when viewing the thumbnails of the pics that are all OK
interesting to note that the last image/thumbnail before the corrupt ones
has horizontal bands from about half way down to the end of the pic,
about 6 bands of rainbow colours!

then when I open this .DEF in photoshop it renders the entire image in steps
and same bands as the thumbnail but it is all in black!

stuffed if I know, lets see what the pro mode comes up with.

Try SanDisk site too. They link to http://www.cardrecovery.com/ and Rescue Pro

Also you could try Nikon Transfer and ViewNX and see what they do with the files. I take it you can see the files on the card. Can you copy them from the card? If so that would suggest the card is readable but the image is corrupt.

[steamy]

No, can't see those images in question on the card when in the camera,
all I get is the red box with a red cross through it!!!!

I can copy the files and they show being the same size ~10mb as the good ones
but no exif data and no image or thumbnails.

Pics were the last series of bungle bungles and Argyle Diamond mine!

Have most of the Bungle ones to keep me happy and the Argyle ones,
well at the end of the day I can live without those.

[steamy]

photorescue seems to be stuck on the first of the damaged files.
here is a screenshot of the last one with that banding I was talking about...

[steamy]

also,
when I am looking at the thumbnails directly off the SDHC card the thumbnail
for that image with the banding shows that the image is all good!
it's image _DSC4350.NEF

Think you might have done the damage when changing the lens with the camera on, you might try Disk Utility to see if there is anything on there, I can't see anything in Nikon Transfer or View that will help, but Card Rescue looks promising, give that a try. good luck with it, I feel for you.

[mcdesign]

That banding is a corrupt file, no way that I know of to rescue that one

[steamy]

Tried CardRescue nothing!
Just had a look at ViewNX nothing just tells me that those files are "unsupported file type"

To be honest I can't recall exactly when I changed the lens.
But as mentioned I tried to replicate that scenario and the images were all good.

[mcdesign]

I did a google on recovery software, this in one http://www.panterasoft.com/file-recovery/index.html
and these are what came up...
http://www.google.com.au/search?hl=e...=&oq=&gs_rfai=

Just keep on trying!

this sounds promising

[steamy]

thanks will have a look
As mentioned, I'm a mac user so it does limit the progs available.

thanks for the links

[steamy]

I have also tried the Stellar Pheonix Photo Recovery app the day after all this happened
and again with no luck!

[steamy]

photorescue couldn't help me out

have tried three diff progs now
me thinks these files are well and truly stuffed and beyond recovery!

[steamy]

I wont wipe or use that SDHC card just yet and try a few other recovery progs
just in case!
