Description
The Test-VHD cmdlet tests a virtual hard disk for any problems that would make it unusable.
Examples
Example 1
PS C:\> Test-VHD -Path Diff2.vhdx
Tests whether the virtual hard disk chain is in a usable state that starts with the virtual hard disk associated with Diff2.vhdx.
Parameters
-CimSession
Runs the cmdlet in a remote session or on a remote computer. Enter a computer name or a session object, such as the output of a New-CimSession or Get-CimSession cmdlet. The default is the current session on the local computer.
Parameter properties

| Value from pipeline: | False |
| Value from pipeline by property name: | False |
| Value from remaining arguments: | False |
-ComputerName
Specifies one or more Hyper-V hosts on which the virtual hard disk is to be tested. NetBIOS names, IP addresses, and fully qualified domain names are allowable. The default is the local computer. Use localhost or a dot (.) to specify the local computer explicitly.
