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.
