G Drive interface error

I have a 6TB G thunderbolt drive. Mac sees it as SATA interface. How do I change it to a thunderbolt interface?

@Peter_Hogarth,

That is correct, it sees it as a SATA interface because it is being recognized over the Thunderbolt interface(which is direct to the PCI bus). That is correct and intended and you will be getting full Thunderbolt speeds.
