Hey David,
been having some problems with my laptop. The graphic card failed and a friend ended up fixing it by formatting my hard drive and re-installing Windows. This even though I told him not to delete ANYTHING. So I have spent weeks trying to my restore the deleted ~66GB of photos, videos etc with different software. I lost almost all of my time-lapse videos and many pictures I created with the help of CHDK. There are some left, some I may be able to recreate but some (most of the videos and maybe half the photos) are lost for good. I haven't been able to use my computer yet, as I am still thinking of new ways/software I could try to save as much as possible. I am still pretty pissed, and I won't be available to try out new things until I have acquired the use of my laptop again.
