Outputting to table format?

God, I feel like a newbie again with Powershell.

I have the following script to get disk data

 function GetData($drive) {
 #This function receives a drive object from the Win32_LogicalDisk WMI class and calculates the total size, freespace, amount used and 
 #the associated percentages.
     PROCESS {
     $obj = New-Object PSObject
     $total = [Math]::Round($drive.size/1gb,2)
     $free = [Math]::Round($drive.Freespace/1gb,2)
     $used = [Math]::Round(($drive.size-$drive.Freespace)/1gb,2)
 
     $PercentUsed = ($used/$Total)
     $PercentUsed = "{0:P2}" -f ($used/$Total) 
 
     $PercentFree = ($free/$Total)
     $PercentFree = "{0:P2}" -f $PercentFree
     $obj | Add-Member NoteProperty Server($drive.systemname) -force
     $obj | Add-Member NoteProperty Drive($drive.name) -force
     $obj | Add-Member NoteProperty Total($total) -force
     $obj | Add-Member NoteProperty Used($used) -force
     $obj | Add-Member NoteProperty Free($free) -force
     $obj | Add-Member NoteProperty "% Used"($PercentUsed) -force
     $obj | Add-Member NoteProperty "% Free"($PercentFree) -force
     $obj | Add-Member NoteProperty Volume($drive.volumename) -force
     Write-Output $obj 
 
 }
 }
 
 $currentdate = get-date # Get the current date
 Write-Output "SERVER DISK USAGE AS OF" $currentdate   #Write the title
 
 $servers = gc c:\temp\test.txt
 
 
 foreach ($server in $servers) { 
 $disks = Get-WmiObject Win32_LogicalDisk -ComputerName $server | Where-Object {$_.DriveType -eq 3} 
 
 foreach ($d in $disks) {
     GetData $d
     }
 }
 

The output, however, comes out like this

Server : D02DI0908216R
Drive  : E:
Total  : 6.17
Used   : 0.05
Free   : 6.11
% Used : 0.81 %
% Free : 99.03 %
Volume : SDMCACHE

From what I've read on MSDN it SHOULD output in a table format (rows and columns) with column headings but I can't see to get it to do that.  Any idea what I'm doing wrong?

Well, I've managed to do it like this now

 $drives = gwmi win32_logicaldisk -filter "drivetype=3" -ComputerName (gc c:\temp\test.txt) 
 
 $total = @{n="Total";e={"{0:N2}" -f ($_.Size/1GB)}} 
 $free = @{n="Free";e={"{0:N2}" -f ($_.FreeSpace/1GB)}} 
 $used = @{n="Used";e={"{0:N2}" -f (($_.Size-$_.FreeSpace)/1GB)}} 
 $server = @{n="Server";e={$_.__SERVER}} 
 $drive = @{n="Drive";e={$_.NAME}} 
 $volume = @{n="Volume";e={$_.VOLUMENAME}} 
 $PercentUsed=@{Name=”% Used”;Expression={‘{0:P2}’ -f(($_.Size/1gb-$_.freespace/1gb) / ($_.size/1gb))}}
 $PercentFree=@{Name=”% Free”;Expression={‘{0:P2}’ -f(($_.freespace/1gb) / ($_.size/1gb))}}
 
 $drives | Select $server,$drive,$total,$used,$free,$PercentUsed,$PercentFree,$volume | ft | Out-File c:\temp\diskspace.txt
 

That works just fine but it seems a bit messier than the object-oriented method above (which I can't get to work).

OK, here's the final version I've settled on but there's ONE issue.

 Get-WMIObject Win32_LogicalDisk -filter “DriveType=3" -computer (Get-Content c:\temp\serverlist.txt) | ` 
 Select @{Name="Server";Expression={$_.SystemName}},` 
 @{Name="Drive";Expression={$_.DeviceID }},`
 @{Name=”Total”;Expression={([string][Math]::Round($_.size/1gb,2))+ " Gb" }},`
 @{Name=”Used”;Expression={[string][Math]::Round(($_.size-$_.freespace)/1gb,2)+ " Gb"}},`
 @{Name=”Free”;Expression={[string]([Math]::Round($_.freespace/1gb,2)) + " Gb"}},`
 @{Name=”% Used”;Expression={“{0:P2}” -f(($_.size/1gb - $_.freespace/1gb)/($_.size/1gb))}},`
 @{Name=”% Free”;Expression={“{0:P2}” -f(($_.size/1gb - $_.freespace/1gb)/($_.size/1gb))}},VolumeName| Format-Table -auto 
 

This produces output like this

Server Drive Total Used Free % Used % Free Volume
------ ----- ----- ---- ---- ------ ------ ------
SERVER1 C: 14.66 8.49 6.18 57.88 % 42.12 % SYSTEM
SERVER1 D: 53.67 0.36 53.31 0.67 % 99.33 % DATA
SERVER1 E: 6.17 0.05 6.11 0.88 % 99.12 % SDMCACHE
SERVER2 C: 14.66 7.95 6.72 54.19 % 45.81 % SYSTEM
SERVER2 D: 53.67 0.08 53.59 0.14 % 99.86 % DATA
SERVER2 E: 6.17 0.03 6.13 0.54 % 99.46 % SDMCACHE

And I would prefer a blank line separating the servers, so like this

Server Drive Total Used Free % Used % Free Volume
------ ----- ----- ---- ---- ------ ------ ------
SERVER1 C: 14.66 8.49 6.18 57.88 % 42.12 % SYSTEM
SERVER1 D: 53.67 0.36 53.31 0.67 % 99.33 % DATA
SERVER1 E: 6.17 0.05 6.11 0.88 % 99.12 % SDMCACHE

SERVER2 C: 14.66 7.95 6.72 54.19 % 45.81 % SYSTEM
SERVER2 D: 53.67 0.08 53.59 0.14 % 99.86 % DATA
SERVER2 E: 6.17 0.03 6.13 0.54 % 99.46 % SDMCACHE

Any ideas how to do that?

I think to get a space between each server, I would do it like this (untested):

Get-Content c:\temp\serverlist.txt | %{ gwmi Win32_LogicalDisk -Filter "DriveType=3" -Computer $_ | INSERT MASSIVE SELECT STATEMENT HERE | Format-Table -auto; ""}

That "" on the end should output a blank line after each server has been processed.
