Macbook stating The SeaGate disk you inserted was not readable by this computer.

I'm attempting to back up my photos on my macbook. I bought a seagate backup disk but when I plug it in, my macbook is stating "The disk you inserted was not readable by this computer." I bought this backup disk specifically because it was compatible with both apple OS and windows OS.

MacBook, macOS 10.13
