I shut  down the machine so I could open it up and see which sata port that drive was plugged into.  I was wrong earlier when I said it was plugged into one of the sata ports on the motherboard.  It was plugged into an addon card that's plugged into a pcie slot. I have a trayless hot swap mobile rack I use for drives I use for backups.  I switched the two sata  cables.  The internal drive now connects to the motherboard.  The hot swap rack connects to the sata addon card.  I rebooted and the internal drives don't show..  Apparently anything connected to the sata ports on the motherboard is treated as an internal drive and anything conneccted to an addon cars is treated as an external drive whether it is or not.
