# Get-PhysicalDisk
# | Select-Object DeviceId,SerialNumber,FriendlyName,ObjectId
# | Sort-Object { [int]$_.DeviceId }
# | Format-List
#
# We take the last UUID contained in the ObjectId after PD, as it seems to be
# the only real(?) unique identifier that works for all kinds of disks.
#
# DeviceId might change sometimes, depending on the disks physically connected
# to the computer. SerialNumber is not unique for some disks and just reports
# 00000000000000000000.
