Hardware inventory – Add firmware property to WMI class Win32_Diskdrive in ConfigMgr


There was a question on the Tech konnect facebook group the other day if there was any way of collecting disk name and firmware version from your clients in ConfigMgr.

Yes you can do this with the help of Hardware inventory and the Win32_DiskDrive WMI Class and use the following properties Caption and Firmware Revision but the thing is that the property Firmware Revision isn’t available by default so we need to add this
to the Win32_DiskDrive class in ConfigMgr Hardware inventory and i’m going to show you how to do this with the help of Powershell.


Getting started

First of all lets have a look on a Win10 client pc just to show of the information we want to gather. Caption is a good way of finding out the name and model of the disk tho different manufactures has there own way of naming things and then Firmware Revision to find out what firmware its running.


Get-WmiObject -Class Win32_DiskDrive | Format-List -Property Caption, Firmwarerevision




If we turn to ConfigMgr and Hardware Inventory classes Administration – Client Settings – <Your Client Setting> – Properties – Hardware Inventory – Set Classes

We can see that under the Win32_DiskDrive class we already have Caption but there’s no Firmware Revision property to be found.




Adding Firmware Revision to the Win32_DiskDrive class in ConfigMgr


We are going to this with the help of Powershell and here’s the script

Note: Make sure to modify the $Namespace variable so that the Site_Code is correct for your environment



#Modify Namespace to your correct Site ID
$Namespace = "root\SMS\site_TS1"

$Win32_DiskDrive = (Get-WmiObject -Namespace $Namespace -Class SMS_InventoryClass -ComputerName localhost | Where-Object {$_.ClassName -like "Win32_DiskDrive"})
$Classprop = [wmiclass]"$($Namespace):SMS_InventoryClassProperty"

$Prop = $Classprop.CreateInstance()
$Prop.PropertyName = 'FirmwareRevision'
$Prop.IsKey = $false
$Prop.Type = 8
$Win32_DiskDrive.Properties += [System.Management.ManagementObject]$Prop


Run the script on your ConfigMgr Siteserver



Go back to ConfigMgr and Administration – Client Settings – <Your Client Setting> – Properties – Hardware Inventory – Set Classes

and under Win32_DiskDrive you will now find “FirmwareRevision” and lets mark that checkbox and press “ok”



 Now you need to wait for the next Hardware inventory data to get back in to ConfigMgr and onces thats done you can go to “Assets and Compliance – Devices – <Right click on a Client> – Start – Resource Explorer”




 And from here go to “Hardware – Disk Drives” and double click on the row to the right which indicates the different disk and you will get a list of all properties and there you also have Firmware Revision




Now when you have the data in ConfigMgr  you can make a report out of it or build collections and so on.
