Mount Point in PowerShell
===

I'm trying to create a mount point using Powershell. it's done locally, and here is the code & issue i'm having.

    $choice = "t"
    New-Item -ItemType directory -Path "E:\Data\Riptide\Ariis\Ris\Docs\interPrimary1\"
    $orgdrive = "E:\Data\Riptide\Ariis\Ris\Docs\interPrimary1\"
    $driveLetter= $Choice + ":\"
    $driveinfo=get-wmiobject win32_volume | where { $_.driveletter -eq $choice + ":" } | select-object DeviceID
    Mountvol $orgdrive $driveinfo

When executed, I get that the parameter is incorrect. 

Thanks in advance.
