Wanted to let you know that I haven't given up on trying to get my data back. Just went through a large wave of distractions, AND an admittedly significant wave of Linux-fatigue. I'll get back to this in the near future - because I need it. But right now am working on getting rid of a small but significant set of lingering priorities. Once I have those settled - hopefully within the next few weeks - I'll be back on this recovery.
I think the first thing I will do is go back through all of our communications and document all the commands that were tried before, and try to make sense out of all of it and create something of a "flow".
Hope you're doing well and not impacted by COVID-19.
