Unlock the wireframe by clicking the padlock icon, then use the following mouse inputs and keyboard shortcuts:

• Use Left-click to select a drive bay
• Use Right-click to rotate
• Use Right-click + CTRL to move
• Use Mousewheel or Right-click + SHIFT to zoom

This issue appears to impact multiple Add-Ins, not just WHS Disk Management. It looks like WHS sometimes has an issue reading an MSI package for the first time, and logs incorrect information in the registry.

Luckily, WHS refers to Add-In MSI files by filename. If WHS doesn't show WHS Disk Management as a valid Add-In to install after you've copied it to the \\server\software\add-ins\ folder, try renaming the MSI file to "newWHSDiskManagement.x.x.x.x.msi" or similar.

For more information see this bug I posted on Microsoft Connect.

It is important that you uninstall the previous version first. Your settings will be preserved during the upgrade process.

Step-by-step instructions:

1. Uninstall the current version using the WHS Console.

2. Download the latest WHS Disk Management MSI to \\server\software\add-ins\.

3. (Optional) Delete the old MSI.

4. Install the latest version using the WHS Console.

Click the "cog-with-green-arrow" icon in the WHS Disk Management toolbar, on the top right of the window,

Windows Home Server "balancing storage" doesn't necessarily mean spreading files evenly across all disks. One disk with significantly higher usage than others doesn't indicate a problem.

For more information see the Drive Extender Whitepaper from Microsoft.

Prior to Power Pack 1, Microsoft only counted storage inside shared folders as taking up space in the Storage Pool. WHS Disk Management looks at all the space used on individual drives, including files outside the Storage Pool.

Some combinations of disks and disk controllers do not present this information to Windows via WMI. Sometimes rolling back to the default Windows drivers will work (reverting to stock Windows drivers works for NVIDIA nForce4 chipsets).

If your SATA controller has IDE emulation or compatibility mode enabled, your disks are identified as IDE. This can mean disk locations are erroneously identified as IDE Master or Slave.

Windows identifies SATA disks (that are not using IDE compatibility mode) as SCSI. This does not indicate an problem.

A red drive bay indicates that WHS Disk Management believes that the disk associated with that drive bay is missing. You will most likely see this for USB/1394 disks that you have disconnected.

If the disk will be missing for a long time, consider marking the drive bay as "Empty" in the Settings dialog.

This can be caused by an Add-In that allows you to minimise the WHS Console application.

To resolve the issue, restart your Windows Home Server or reset the console (Options --> Reset the WHS Console from the Console login screen).

We write all our settings to D:\folders\{AD6D2DAD-BBCB-4C4D-878C-A8A19935FD0A}\ on the server. Settings are preserved through upgrades of the Add-In; uninstalling the Add-In does not remove your settings.

If you want to entirely remove WHS Disk Management from your system, you will need to delete these XML files as well. The GUID folder cannot be deleted, however; if you delete the folder, WHS will recreate it on the next boot (this is a limitation of WHS Application Folders).

Sometimes WHS doesn't successfully uninstall some Add-Ins; you end up in a state where the WHS Add-Ins tab shows that an Add-In is installed, but the Add-In isn't loaded and you can't install an updated version.

To manually uninstall any WHS Add-In, follow these steps:

1. Make a note of the name of the Add-In that cannot be uninstalled ("WHS Disk Management 1.0.4.0" for example).

2. Log into WHS using remote desktop.

3. Locate the Add-In in Add/Remove Programs and uninstall it.

4. Open regedit and locate HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Home Server\RegisteredAdditions\.

5. Locate the subfolder that references the name of the problem Add-In ("WHS Disk Management 1.0.4.0" for example) and delete it.

6. Open and then close the WHS Console from within the remote desktop session (to free up any in-use files).

7. Navigate to C:\Program Files\Windows Home Server\.

8. If present, rename the Add-In file ("HomeServerConsoleTab.DiskMgt.dll" for example) to remove the DLL extension ("HomeServerConsoleTab.DiskMgt.xxx").

9. (Optional) Install the desired version of the Add-In through the WHS Console as normal.

No, WHS Disk Management does not run as a service. This means that when the Windows Home Server Console is closed, WHS Disk Management is not running and cannot send alerts.
