Initialize and format windows disk with powershell

Sometimes you may need to automatically create windows disk for a virtual server using an automation mechanism. With the below powershell you can initialize a new emtpy disk with GPT partition and format it according to your needs.

You can get your available disks using:

Get-Disk

You can use the below powershell and change the below settings:

DriveLetter : What your drive letter will be
AllocationUnitSize: Default is 4k, but in my case I define 64k
DiskNumber: number of disk from Get-Disk command
NewFileSystemLabel: name of the volume

 Initialize-Disk -number 4 -partitionstyle GPT ; New-Partition -DiskNumber 4 -UseMaximumSize ; Format-Volume -DriveLetter G -FileSystem NTFS -AllocationUnitSize 65536 -NewFileSystemLabel Volume-Name

After applying the volume will be created and initialized.
