Back later - time for wifey and I to head to church.
Oops, I forgot to add one thing: I’ll likely also install a copy of Win 11 Pro on the 3rd drive, as a quick “reserve” in case a Windows Update kills the OS on the C: drive. That came in really handy when the Win 10 Pro machine got whacked: I was back up and running (for the most part) within minutes.
