PowerShell Formatting Output

Hey Experts,

I have a PowerShell script that pulls WMI information for a server to get the specs of the machine.  When I query win32_logicaldisk I get back the information on disk space, it comes back as:

DriveSpace: @{DeviceID=C:; Size=64422408192} | @{DeviceID=E:; Size=32209104896}

But I'd like for it to show up as:
C: 64422408192 | E: 32209104896


If at all possible I'd rather have it in GBs but when I try to use any sort of calculation on it, it doesn't bring back anything for the drive space.

Below is the script I'm using:

cls
$serverlist = @("Server1")
foreach ($server in $serverList ){ 
$CPU = gwmi win32_processor -ComputerName $server -Property "systemname","deviceID","maxclockspeed","addressWidth","numberOfCores","NumberOfLogicalProcessors" | Select "systemname","deviceID","maxclockspeed","addressWidth","numberOfCores","NumberOfLogicalProcessors" 
$Disk = gwmi win32_logicaldisk -ComputerName $server -Property "DeviceID","Size","FreeSpace","VolumeName" | Select "DeviceID","Size","FreeSpace","VolumeName" | Where-Object {$_.Size -ne $null}
$ServerSpecs = "" | Select Computer,NumCPUs,CPUSpeed,Bit,DriveSpace
$ServerSpecs.Computer = ($CPU | Select systemname -Unique).systemname
$ServerSpecs.NumCPUs = (($CPU.NumberofLogicalProcessors) | Measure-Object -Sum).Sum
$ServerSpecs.CPUSpeed = ((($CPU.maxclockspeed | Measure-Object -Average).average)/1000.0).ToString() + " GHz"
$ServerSpecs.Bit = ($CPU.addressWidth | Measure-Object -Average).average
$ServerSpecs.DriveSpace = ([string]::Join(' | ',($Disk | Select "DeviceID","Size")))
$ServerSpecs
}

Open in new window


Which brings back the following information:

Computer   : Server1
NumCPUs    : 2
CPUSpeed   : 3.456 GHz
Bit        : 64
DriveSpace : @{DeviceID=C:; Size=64422408192} | @{DeviceID=E:; Size=32209104896}

The reason you're getting that output is because you're joining (complex) objects (i.e. with properties), rather than just simple string objects.

Try substituting this for line 11.
$ServerSpecs.DriveSpace = ($Disk | % { "{0} {1:N2} GB" -f $_.DeviceID,($_.Size / 1GB) }) -join " | "
