[<CommonParameters>]Description
The New-VHD cmdlet creates one or more new virtual hard disks in either VHD format or the newer VHDX format. The file name extension you specify determines the format.
Examples
Example 1
PS C:\> New-VHD -Path c:\Base.vhdx -SizeBytes 10GBThis example creates a dynamic virtual hard disk in VHDX format that is 10 GB in size. The file name extension determines the format and the default type of dynamic is used because no type is specified.
Example 2
PS C:\> New-VHD -ParentPath c:\Base.vhdx -Path c:\Diff.vhdx -DifferencingThis example creates a VHDX-format differencing virtual hard disk with a parent path of c:\Base.vhdx.
Example 3
PS C:\> New-VHD -Path C:\fixed.vhd -Fixed -SourceDisk 2 -SizeBytes 1TBThis example creates a 1 TB VHD-format fixed virtual hard disk at the specified path. The data for the virtual hard disk is populated from the disk identified in the system by the number 2. You can list the disks attached to the system and the number associated with each disk using the Get-Disk cmdlet.
Example 4
PS C:\> New-VHD -Path c:\LargeSectorBlockSize.vhdx -BlockSizeBytes 128MB -LogicalSectorSize 4KB -SizeBytes 1TBThis example creates a new 1 TB VHDX-format dynamic virtual hard disk at the specified path with a block size of 128 MB and a logical sector size of 4 KB.
Example 5
PS C:\> $vhdpath = "C:\VHDs\Test.vhdx"
PS C:\> $vhdsize = 127GB
PS C:\> New-VHD -Path $vhdpath -Dynamic -SizeBytes $vhdsize | Mount-VHD -Passthru |Initialize-Disk -Passthru |New-Partition -AssignDriveLetter -UseMaximumSize |Format-Volume -FileSystem NTFS -Confirm:$false -ForceThis example creates a new 127GB VHD and then mounts, initializes, and formats it so the drive is ready to use.
Parameters
