.SYNOPSIS
    Warning Destructive - Created to run in WinPE OSD to Clear-Disk and assign OSDDiskIndex to task sequence Disk Advanced Option Partition Variable
.DESCRIPTION
    Runs in WinPE OSD to find, sort and format disk drive(s) and assign fastest and smallest disk as OSDDiskIndex variable to be used in the
    task sequence
