Review the syntax of the command again at https://www.tonymacx86.com/threads/unibeast-8-troubleshooting-notes.235489/ # 19 to see where you went wrong.

I just had the same issue and this is exactly what I posted in my terminal command: sudo diskutil partitionDisk /dev/disk2 GPT JHFS+ USB R. Ran unibeast again and it went through successfully.
