Q80021801 - The ARC-8050T3-12 needs to partition it in Disk Utility it says the partition map is not supported and the partition button is grayed out.

macOS 10.13's Disk Utility 17.0 (1626) does not recognize unformatted disks unless you click View > Show All Devices, quit Disk Utility, then relaunch it. But Diskutil does recognize the drive. You use it to perform a quick, cursory format (e.g., diskutil eraseDisk JHFS+ NewDisk GPT disk0) to make the disk appear in Disk Utility. The link below found on internet.
