Many thanks for all who responded to this. I should have been more patient. When I did not hear back for a few days, I decided to do a rebuild with a more modern Mobo, CPU, dramatically enhanced amount and quality of RAM, plus 2- 2TB m.2 drives and 2- 1TB SSD added to the new system.
The old Mobo, CPU, RAM, cooler, graphics card, NIC and power supply going to my granddaughters for their first PC build.
Truth be told, it appears that I was clearly, if somewhat unconsciously, just looking for an excuse to do this upgrade.
I apologize for not waiting longer to work on the excellent solutions provided. These wonderful responses tell me that the Unraid community is very helpful and caring about and within its members. I will endeavor to be a positive actor in that community, my inherent impulsiveness notwithstanding.
Warm Regards, Mike
