SD card problem - images lost !
Discussion
I bought a 4gb kingston sd card for my D50 just before i went on holiday. The first 186 raw shots (about 1gb exactly) are fine, but after that, when taking a shot i still get the preview of the shot on the screen, but if i want to zoom in or look at the image later, it says "File does not contain image data". I've read online that the D50 does not support or format 4gb cards, but the first 186 files are fine, its the ones after that i cannot view even though they are 5+mb filesizes as i'd expect. Rawshooter and CS2 wont open the files. Is there anything i can try or am i stuffed? Be a real shame to have lost all my snaps from (Steve Irwins) Australia Zoo 
Here's a link to a non-viewable raw file (5.3mb) if anyone knows how to get the image from it

I've had sucess with this in the past.

I'm not sure if it will work with your problem but It's worked for me.
They used to do a demo version to see if it works.

That file contains a regular pattern of bytes (xx DC 03 00 - where xx increments by 1, starting at 01 and ending at 80) repeating every 512 bytes throughout the file. I don't know what a raw file ought to look like, but I strongly suspect it ain't like this...

Bad Cards & Accidental Erasures
One of the worst things that can happen on a shoot is to find oneself with a corrupted or accidentally erased memory card. I'll tell my own anecdote in a moment, but first I should mention that when you have 50 photographers working together for three weeks, and the giggage mounts up, accidents and misadventures are bound to happen.
We had at least a half dozen instances of people who had corrupted memory cards, or who needed to recover files from cards once they had been reformatted. Fortunately a couple of people had a program on their laptops called Photorescue, which in every instance was able to save the day.
Other data recovery programs, such as those now provided free by card makers such as Sandisk and Lexar just didn't cut it. Sometimes a few files could be recovered, but not always, and not all files. With PhotoRescue a complete recovery was possible almost every time. As soon as I got home I downloaded a copy – it's available for both Windows and Mac OSX. Don't leave home without it. A review on Imaging Resource tells you all about this fine and inexpensive program.
My own near disaster occurred after the first day ashore shooting in South Georgia with the Hasselblad and P45 back. My usual routine is to copy cards to a hard drive and then once safely copied, to start reviewing them. But since I have now changed my workflow to Lightroom, and like its ability to import from a card reader to two drives simultaneously (thus making a backup in real time), this is what I did, along with shots made with my Canon 1Ds MKII.
That evening in my cabin after dinner, once the files were all copied over, I started reviewing the thumbnails on screen. Everything looked fine, and so pouring another glass of wine I popped the CF cards into the P45 and reformatted them for use the next day.
I then saw one particular thumbnail that looked interesting and clicked on it to view at full size. Oh oh! Nothing happened. What I quickly discovered was that Lightroom had only imported the P45's built in thumbnails, not the entire file. (P45 files are not "officially" supported by Lightroom. Thomas Knoll had kindly put in preliminary support for P45 files for Bill Atkinson and me for our Lightroom shoot in Iceland in summer '06). Please note that this bug does not exists with any other type of camera files.
I tried two file recovery programs that I had on my Macbook, but nothing would recover the files. I then went to the ship's bar (our evening hang-out), and asked if anyone had any stronger medicine. A couple of people had Photorescue, and within the hour 97 of 102 files on the card had been rescued.
This story was to be repeated throughout the trip, with someone every day or two having either a corrupted or accidentally formatted card, and every time full or almost full recovery was possible. Forewarned is forearmed.
Ps: The P45 / Lightroom solution was to go back to what I had always been doing, which is to copy the files from the card to a hard drive, and then Import into Lightroom, rather than to use the program's auto-import function. Of course Auto-import worked perfectly with all my other camera files.
