List physical drive space

Question

I have around 200 servers and I need to get the disk space & logical drive space details (free space, used space & total space).

Here is my PowerShell query.

Answer 1

I would like to point that there is several places where error could occur. The purpose of this answer is to address the unknown number of headers. I would recommend that you run this in place to see what it is trying to show you before you attempt to integrate this.

# Gather all wmi drives query at once
$alldisksInfo = Get-WmiObject –query "SELECT * FROM Win32_DiskDrive" -ComputerName $servers -ErrorAction SilentlyContinue | Group-Object __Server

# Figure out the maximum number of disks
$MaximumDrives = $alldisksInfo | Measure-Object -Property Count -Maximum | Select-Object -ExpandProperty Maximum

# Build the objects, making empty properties for the drives that dont exist for each server where need be. 
$servers | ForEach-Object{
    # Clean the hashtable
    $infoObject = [ordered]@{}

    # Populate Server
    $infoObject.Server = $_    

    # Add other simple properties here
    $infoObject.PhysicalMemory = (Get-WmiObject Win32_PhysicalMemory -ComputerName $infoObject.Server | Measure-Object Capacity -Sum).Sum/1gb

    # Add the disks information from the $diskInfo Array
    $serverDisksWMI = $alldisksInfo | Where-Object{$_.Name -eq $infoObject.Server} | Select-Object -ExpandProperty Group

    for($diskIndex =0; $diskIndex -lt $MaximumDrives;$diskIndex++){
        $infoObject."PhysicalDisk$diskIndex" = [Math]::Round(($serverDisksWMI | Where-Object{($_.DeviceID -replace "^\D*") -eq $diskIndex} | Select -Expand Size)/1GB)
    }

    # Create the custom object now.
    New-Object -TypeName psobject -Property $infoObject
} # | Export-Csv ....

Since this uses the pipeline you can easily add export-CSV on the end of this.
