Find Volume number in Powershell

Question

I want to link volume number and drive letter on a remote device.

The output from diskpart is like this

Volume ### Ltr Label Fs Type Size Status Info

---

Volume 0 E DVD-ROM 0 B No Media
Volume 1 System Rese NTFS Partition 350 MB Healthy System
Volume 2 C NTFS Partition 49 GB Healthy Boot
Volume 3 D Data NTFS Partition 99 GB Healthy
Volume 4 L Logs NTFS Partition 49 GB Healthy
I want to retrieve the the Volume## value for a given drive letter. So if I'm interested in drive letter D I want Volume 3 returned.

I tried running diskpart remotely using this
$part = Invoke-Command -Computername $vm -scriptblock {$commands=@('list volume');$commands | diskpart}

$part comes back as a System.Array and I can't seem to do much to separate the strands.

I can't seem to find the correct WMI call to retrieve the Volume information. Does anyone know what it is?

Hi，

The diskpart volume number cannot be found in the WMI class Win32_Volume. You have to parse the output of diskpart

$letter = "C"  
$command = "select vol $letter"    
Invoke-Command -Computername $vm -scriptblock {  
    $using:command | diskpart| foreach{  
        if($_ -match "Volume \d+"){  
            $Matches.Values  
        }  
    }   
}
