1. Overview Get-VHD is a PowerShell cmdlet used to retrieve information about one or more Virtual Hard Disk (VHD/VHDX) files. It is essential for administrators managing Hyper-V virtual machines, storage migration, or performing disk health checks. The cmdlet works on both locally stored and remote (SMB) virtual hard disks. 2. Syntax (Common Usage) Get-VHD [-Path] <String[]> [-ComputerName <String[]>] [-CimSession <CimSession[]>] [<CommonParameters>] 3. Key Parameters | Parameter | Description | |-----------|-------------| | -Path | Specifies the full or relative path to the VHD/VHDX file (wildcards supported). | | -ComputerName | Targets a remote Hyper-V host (default is local computer). | | -CimSession | Uses a CIM session instead of WS-Management for remote queries. | | -DiskNumber | Retrieves VHD info by the disk number mounted in the host OS (Windows 10/Server 2016+). | 4. Output Object Properties Get-VHD returns a Microsoft.Vhd.PowerShell.VirtualHardDisk object with critical attributes: $child = Get-VHD -Path "C:\VMs\child

| Property | Description | |----------|-------------| | Path | Full path to the VHD/X file | | VhdFormat | VHD (legacy) or VHDX (modern) | | VhdType | Fixed , Dynamic , or Differencing | | FileSize | Current file size on disk (bytes) | | Size | Maximum virtual disk capacity (bytes) | | ParentPath | Path to parent disk (if differencing) | | DiskIdentifier | Unique GUID of the virtual disk | | BlockSize | Block size in bytes | | LogicalSectorSize | 512 or 4096 bytes | | IsAttached | Boolean indicating if the VHD is currently attached to a VM or the host | a. Basic Disk Information Get-VHD -Path "D:\VMs\Server01\disk.vhdx" b. Batch Inspection Get-VHD -Path "D:\VMs\*\*.vhdx" | Select Path, FileSize, VhdType c. Differencing Disk Chain Validation Get-VHD -Path "C:\ClusterStorage\Volume1\child.vhdx" | Format-List ParentPath, VhdType d. Remote Server Query Get-VHD -Path "\\HV02\D$\VMs\Disk.vhd" -ComputerName HV02 e. Health & Block Status $vhd = Get-VHD -Path "E:\Data\disk.vhdx" $vhd | Get-VHD -Detailed | Select-Object *Block*, *Sector* 6. Practical Examples Example 1: Find all dynamically expanding VHDX files larger than 100GB The cmdlet works on both locally stored and
