Cannot partition external drive in high Sierra

Under 10.13.13 macOS HIGH SIERRA, disk utility cannot restore (restore will fail with errors) or partition (greyed out)  external hdd

solution:
1. issue diskutil list to find which dev for corresponding hdd, eg. dev12
2. issue  diskutil erasedisk hfs+ External GPT /dev/disk12 
after erased to GPT hdd, go back to disk utility, all should be set
