"Preserving" means checking integrity and authenticity
No it doesn't. Look at every definition of "preserve" and "preservation" on the planet Earth. What you are doing is integrity checking of preserved data. There is a difference. I spent my entire childhood in museums helping to preserve tens of thousands of artifacts, as my father was director & currator of several museums in our area. I know real preservation.
I am not either, as I clearly stated in the thread and explained why. There is no post read manipulation done to the data. You stuck your foot in your mouth and tried to claim that the image posted by DrCoolZic was modified, and its not. Adding the post read normalization cures the generational copy issue.
Not much comment to me they look the same
Therefore my advice cleanup the disk before sampling
Yep, I told you it was important! ... and look at the SCP dump after cleaning - still superior to Kryoflux.
I can switch sampling rates with SCP on the fly, from 25ns to 100ns samples, in 5ns increments. Perhaps I should make that an option that is available? You *will* see a difference in the image data, and it only makes sense. If a bit cell time is 4001ns and you are sampling at a 50ns rate, that bit cell time will appear as 4050ns, and even with multiple reads of the same data there is no way for the hardware (or software) to know that it was only 1ns off from being 4000 instead of 4050. That's the reality.
