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

-Path

Specifies the path to the virtual hard disk file of the virtual hard disk to be tested. If a filename or relative path is specified, the new virtual hard disk path is calculated relative to the current working directory.

Type:String[]
Aliases:FullName
Position:0
Default value:None
Required:True
Accept pipeline input:True
