# Description
# This script is to be used when you have a RAW vmdk disk and fear that
# the drive identifier, i.e. PHYSICALDRIVEX might change during reboots.
# This script finds the correct name matching to a configured serial and
# will remove the old drive and remove it, create a new one and attach it.

#
# Configuration
#

# The serial of your drive. You can find this by running the command
# wmic diskdrive get name, serialnumber
# And find out which PHYISCALDRIVE yours is, then you can find the
# corresponding serial
