Did all sorts of self-help stuff first to identify, then fix the problem. This included testing the RAM and my numerous reinstalls. Possible that this drive just doesn't play nice with WIndows 10 for some reason.
It was very fast and worked well for a few months; Through August and most of September I had no problems
Then I started getting error messages about Windows being corrupted; Next thing I know the drive is completely wiped; I reinstall Windows on it, woks fine for a day or two, then has registry issues; Wiped it myself this time and reinstalled again.
