Question Formatting a 4tb drive

How would I go about formatting this drive?
Thanks.

From the commandline, diskpart and the clean command.

How to Diskpart Erase/Clean a Drive Through the Command Prompt | Support Seagate US

This article explains the Microsoft Diskpart Erase utility. The command that erases the drive during this process is "Clean". In this article "Clean" and erase are used interchangeably. Cleaning or erasing a storage device removes all data and partitions from the drive.
