In a previous post I showed how to get remote disk information with PowerShell. The script works nice until you execute it on a server with Mount Points. When executing the following script on a server with Mount Points:

Get-WmiObject win32_logicaldisk -computer <computername> | 
select-object DeviceID, VolumeName, @{Name="Size";Expression={$_.Size/1GB}},@{Name="FreeSpace";Expression={$_.FreeSpace/1GB}},
@{Name="PCTFreeSpace";Expression={
$_.FreeSpace/$_.Size*100}}|Sort-Object -descending PCTfreespace|format-table

I get the following result:

Knowing the sizes of my databases, I knew the numbers were wrong. So I opened a RDP session to the server and found this picture in Disk Management:

At that moment I realized I wasn’t getting the information from the Mount Points, just from the Disks that had a drive letter assigned to them.
So let’s find out how we can get that information with Windows PowerShell. I still need the wmiobject but instead of the win32_logicaldisk I’m going to use the win32_volume. I also replace the DeviceID and VolumeName objects with Name and Label:

get-wmiobject win32_volume -computer <computername|
select name, label, driveletter

The result looks like this:

As you can see, the drive letter properties are empty for my Mount Points and in the name column I can find the file and folder where they are mounted.
So let’s find the space, free space and percentage free space of the volumes. I can use the calculations from my previous script only Size needs to be replaced with Capacity:

get-wmiobject win32_volume -computer <computername|
select name, label, @{Name="Capacity (GB)";Expression={$_.Capacity/1GB}},@{Name="FreeSpace (GB)";Expression={$_.FreeSpace/1GB}},
@{Name="FreeSpace (PCT)";Expression={$_.FreeSpace/$_.Capacity*100}} |
format-table

The result now shows the drives and Mount Points with all the requested information:

To be able to reuse the script I do what I did in the other two PowerShell post:

param(
	[string] $compname = $(Throw "Provide a Server name as first parameter")
)
Get-WmiObject win32_volume -computer $compname |
select name, label, @{Name="Capacity (GB)";Expression={$_.Capacity/1GB}},
@{Name="FreeSpace (GB)";Expression={$_.FreeSpace/1GB}},
@{Name="FreeSpace (PCT)";Expression={$_.FreeSpace/$_.Capacity*100}} |
format-table

End that’s it, the next request for free disk space is a matter of seconds again.
