+### Format a storage volume as a Dev Drive from the command line
+
+As an alternative to using Windows Settings, there are two options for creating Dev Drive storage volumes from the command line. Both options require that you open the command line as an Administrator. You must be a member of the Admin group to format a hard drive. These command line formatting methods may be preferred when creating multiple Dev Drives or as an admin for multiple machines.
+
+1. Using the [Format.com](/windows-server/administration/windows-commands/format) command line tool from Windows CMD or PowerShell:
+
+  ```CMD
+  Format D: /DevDrv /Q
+ ```
+
+2. Using the [Format-Volume](/powershell/module/storage/format-volume#-devdrive) cmdlet from PowerShell: 
+
+```PowerShell
+Format-Volume -DriveLetter D -DevDrive
+```
+
+These code samples require that you replace `D:` with the drive location you wish to target. See the links for more options and command parameters.

 ## How does Dev Drive work?
 
 A [Storage Volume](/windows-hardware/drivers/ifs/storage-device-stacks--storage-volumes--and-file-system-stacks#storage-volumes) specifies how data is stored on the file system, via directories and files, in a particular format. Windows uses NTFS for the system drive and, by default, for most non-removable drives. The [Resilient File System (ReFS)](/windows-server/storage/refs/refs-overview) is a newer Microsoft file system format, designed to maximize data availability, scale efficiently to large data sets across diverse workloads, and provide data integrity with resiliency to corruption. It seeks to address an expanding set of storage scenarios and establish a foundation for future innovations.
