Thunderbolt/Firewire adapter backwards compatible?
So I just bought a new 4TB G-Raid w/ Thunderbolt. Additionally, I bought a Thunderbolt to FireWire adapter, so I can connect my Firewire 800 equipped mac to the hard drive. IT DOESN'T WORK 😟. I've read that they only work with a Thunderbolt equipped mac, to a female fw 800 cable. However, the deeper I've dug, I've heard that they are indeed backwards compatible (specifically with the G-tech drives), or that there can be software drivers that can make them backwards compatible. Anyone have any ideas??
