testdisk complains about geometry. I have tried (as
suggested) 16,32,64,128,240,255 heads per cylinder, and none of these results in anything useful; it still complains about "bad ending head".
With the following values (256 cylinders, 255 heads, 63 sectors per track, 512 sector size), what I see is this:

Are there any other values of heads I should try, and if not, what else remains to do? I have created the image.dd file so far.
