Remote Diskpart using Powershell

Question

I am trying to issue the following command (which works fine locally) remotely without the help of WinRM:
$Commands = @"
rescan
exit
$Commands | diskpart.exe
This is what I currently have:
$Computer = "myserver"
$Credential = Get-Credential
$Commands=@"
rescan
exit
iwmi -Path win32_process -Name Create -ComputerName $Computer -Credential $Credential -ArgumentList ($Commands | diskpart.exe) | Out-Null
But it fails with:
Invoke-WmiMethod : Invalid operation
At line:8 char:5
+ iwmi <<<< -Path win32_process -Name Create -ComputerName $Computer -Credential $Credential -ArgumentList ($Commands | diskpart.exe) | Out-Null
+ CategoryInfo : InvalidOperation: (:) [Invoke-WmiMethod], ManagementException
+ FullyQualifiedErrorId : InvokeWMIManagementException,Microsoft.PowerShell.Commands.InvokeWmiMethod
Does anyone know what is happening or have a better method for accomplishing this task?

Hi!
I had a similar need today.  Just published
PSDiskPart.  Long story short, it dumps a diskpart script on the remote system, uses WMI under the covers to launch diskpart, redirects output and errors to independent files on that system, pulls these files in from the remote system.
A quick example, bringing disk 2 online:
On a side note, thanks for the diskpart parsing details Adam, very helpful!
Cheers!
