Export-csv column format

I’m trying to export to csv all disks for each computer from my list. I have computers configured with one, tow of tree disks. Now when I export the result of my script to csv file,I get it in formatted as list format:

ComputerName, Disk
Comp1, C:
Comp1, D:
Comp2, C:
Comp2, D:
I would like to know if it is possible to export this list but as table? If there are more then one disk in computer add a column to the table, something like this:

ComputerName, Disk1, Disk2…
Comp1, C:, D:
Comp2, C:, D:
Comp3, C:

Here is my script :

$computers = ‘Comp1’,‘Comp2’

$out_csv =@()

foreach ($computer in $computers) {

$disks = Get-WmiObject -Class win32_logicaldisk -ComputerName $computer| select deviceid, volumename

foreach ($disk in  $disks) {

    $ou = New-Object -TypeName psobject -Property @{

        'Computer' = $computer
        'drive' = $disk.volumename
        'ID' = $disk.deviceid

    $out_csv += $ou


$out_csv | Export-Clixml -Path ‘C:\Users\Administrator\disk.csv’


Actually, the way you’re doing it now is the better, “right-er” way to do it. What you’re producing is technically hierarchical data, where every computer has one or more drives. CSV sucks for hierarchical data - it’s designed for flat data. What you’re doing now - one row per computer+drive - is “flattening” the hierarchical data in the best way.

What you’ve asked to do, where you’d have a column for each possible drive, would result in some computers having empty columns (what if one doesn’t have a D: drive, but has an E: drive?), and is harder because you essentially have to combine objects to form an aggregated row.

XML is actually a lot better than storing this kind of data than CSV, because XML supports hierarchies.

If you want to see it graphically, as a report, you can use HTML (ConvertTo-HTML) to generate a report or use an XML Stylesheet: http://www.w3schools.com/xml/xml_xsl.asp

Thanks a lot for your response.
