I have a late 2012 Mac Mini running macOS Sierra (10.12.6). It came with a 1TB fusion drive. I recently removed that drive to replace it with a 960GB SSD. All is working fine except for two issues.

If I restart while hiding down the option key, it shows up there too.
In Terminal, in
diskutil list, it shows up as
disk0. The replacement SSD shows up as
Is there anyway to keep the 'phantom' disk from showing up?
