HDD GURU FORUMS

I have some video footage that I would like to recover. This is from a SD card in my digital camera. I have pictures from before, after and a shorter video I took after are intact. When I transferred the files over the I ended up with a 0k file which should have been the video file I am looking for - somehow was not copied properly - but I have no reason to believe that the data wasn't being written to the sd while the video was actually being shot.

I have used a tool to create an image of the entire SD and believe the data is there - but somehow there is either an error somewhere in the data which broke the file...maybe the header or index got corrupted?

I don't know enough about the structure of how this data would be formatted to describe what is wrong - but what I am looking for is some tool where I can compare the front and tail end of the data block where this video should be (it should be obvious and a very large file relative to the pictures and the other short video I took after this one) so I can either hex edit in a working header to it or use some other technique to make this a complete contiguous file which I can get working.

Thanks in advance for any tips you can offer.

ok have you tried a really good program called isobuster that will work with these type of files

the file you have is not the correct one

then do a scan of the card
and your files should come up

if your only getting half of files then the card has written to the blocks already

What format is it (.avi, .mov etc) ?

Shoot a small test movie and then examine its structure with a hex editor. Then you'll know what to look for.
