|Hope you are feeling OK after your hip surgery.|
I don't see where you are repeating the information I asked for. You still haven't provided it.
"Windows Disk Management" shows more than just the capacity of a hard drive. The information you posted only refers to the model and capacity.
The number your provided in #5 above is NOT the motherboard model but the chipset number. The Motherboard should be printed directly on the printed circuit board, not on one of the chips.
Verify the model of the second hard drive please.
