Kodi won’t recognize my seagate

I have kodi on my firestick. I have been trying to get it to connect to my seagate 5tb external hard drive. It will not recognize it. I have looked in the external drive option as well as the root system under mnt, storage, sDard etc. But nothing. I have used my Xbox one and an Emerson tv as the medium between the firestick and my seagate. Can anyone help?
