if you assembled the raid as was shown on the screenshot, then it's wrong because you started from 0, when with MD raids you need to start from some offset.

from the last post it seems that the MD partition is this - /dev/sda3 133 243138 1951945693 83 Linux
which starts from sector 243138.
but then there's MD metadata, so there's no way to tell what is the raid offset based on what you posted.

also it seems that r-studio could not parse MD super block (it should appear automatically, but i don't see anything on the screenshot).

at this point i can only suggest to download ufs expolorer demo, and check MD raid parameters from it. then u can enter them into r-studio and do RAW scan again

I would recommend ReclaiMe Free RAID Recovery for finding MD RAID parameters.
