Hard Disks column either blank or showing zero drives

Question

The Hard Disks column in the SCE 2010 console is either showing 0 - OK on some of the clients is it monitoring or in the servers group some of the servers have nothing at all displayed in the Hard Disks column. There are also a could of servers showing 0 - OK as well.
Some clients and some servers show the correct number of Hard Disks and if any are over the 50% or 75% thresholds, for example, this is shown in the column as well.
The machines I am monitoring are running a variety of Windows versions and are from a variety of hardware vendors.
I can't see a pattern to be honest. For example, I have some PowerEdge M600 blades and one shows "1 -1 > 50%", another shows "0 - OK" while a third is blank in the Hard Disks column. A PowerEdge 6650 is also blank. They're not exactly obscure hardware kit.
If there's any more info or investigation you would like, let me know.

Some background on the inventory collection in Essentials.
The majority of inventory information, including hard disk information is collected by the Windows Update agent and forwarded to the Essentials server. If the Windows Update agent is not reporting back information then most of the inventory information will not display. The exception is Asset Tag and BIOS Serial number - this inventory information comes from the Monitoring (Ops Mgr) agent.
You can check the basic health of the agents used by Essentials by selecting a computer in in the Computers workspace and then in the preview pane at the bottom, in the Health section click on the link to the right of the word Agents. This will open the Health Explorer window. 
You will see that the Health Explorer shows the health for the 3 agents used by Essentials:
OpsMgr Agent (for monitoring)
Windows Update (for updates, software deployment and inventory)
Virtual Machine Manager (for virtualization on virtual machine hosts)
The Health Explorer will automatically expand items in the tree that don't have a Healthy state. 
In this case, I'm expecting that under the Availability node, the Windows Update Agent will have a warning icon next to one of the 4 monitors used to determine it's health.
The 4 things being checked for are:
Agent Configuration
This checks the group policy to point the Windows Update agent to the Essentials server is in effect and the computer has been added to the correct security groups in Active Directory
Agent Connection
This checks if the Windows Update agent has connected to the Essentials server in the last 24 hours
Proxy Configuration
This checks that makes sure that if a proxy is being used
Service State
This checks that the Windows Update service is running on the comptuer
The Resolutions section of the Knowledge tab for each of the monitors provides some initial troubleshooting steps. Additional troubleshooting can be done by looking at the windowsupdate.log on the computer.
