The following simple script will iterate though your vCenter environment and remove the floppy disk from VMware guest machines that are in a powered off state.

Script text: I used Windows PowerShell ISE

Set-ExecutionPolicy RemoteSigned #may require running as administrator
Import-Module VMware.VimAutomation.Core
Connect-VIServer -Server ‘your.server.here’

$off = Get-VM | where {$_.powerstate -eq “PoweredOff”}
$floppy = Get-FloppyDrive -VM $off
Remove-FloppyDrive -Floppy $floppy -Confirm:$false

Purpose:

The purpose of removing the floppy is to remove potential attack channels to the guest VM itself. It has also been noted that removing such devices will save kernel resources.
