I went into linux mint. I am certain, CERTAIN, that a windows 10 update probably caused a fundamental HD failure on my old computer. I have hard drives much older and more used than the one I had, yet that HD, which was the main HD I had started to fail. It gave enough life for me to back it up into a massive 14TB backup drive (I keep that one unplugged when not in use) so I didn't lose any data.

But HD failures are rare for me. I am fucking glad I was able to save the data. I need to put that drive to some old fashion electronic recycling.
