There is a product called Ghost but I am sure there are others. Also there are hardware devices which will clone a drive. They are fairly cheap.

I suppose the first thing I would try is to make a copy using something like Ghost or dd in Linux. Since these are straight bit copies it probably won't help but it is what I would try first.

You need a phase reference. In an optical system you use two different paths for the light, the light reflected from an object and another beam coherent with the first but taking a different path to the recording medium thus acting as a phase reference.
Last night was a warm North Westerly wind in Christchurch NZ, you couldn't see the sunset for the smoke haze which made the whole sky a pinkish/brown. You could even smell the smoke in the air. Best wishes to all you people in Oz.
