fool proof =
You have a 1TB WD Blue SSD, and a 1TB WD Blue HDD.
The install shows Disk 0 -1TB, and Disk 1 - 1TB.
Which to select and install to?
If you're like me, you choose the Disk 0 because I always put the desired OS drive in the lowest number SATA port, just for consistency sake. I know what drive is the OS drive.
Not everyone is that diligent or consistent.
And I still have all other drives disconnected during the OS install.
