Help with workflows and custom objects

Question

Hi!
I want to create a script or workflow that will inventory computers C: and D: drives. I would like to use a workflow so i can query many computers simultaneously.
Unfortunately I does not get the right output. I get PSComputerName and PSSourceJobInstanceID instead of my variables.
PS C:\Windows\system32> Get-HDDInfo -ComputerName Comp1, Comp2
PSComputerName PSSourceJobInstanceId
localhost d7c95049-27c5-46e2-970f-7b940a656aa3
localhost d7c95049-27c5-46e2-970f-7b940a656aa3
localhost d7c95049-27c5-46e2-970f-7b940a656aa3
localhost d7c95049-27c5-46e2-970f-7b940a656aa3
The Workfow!
Workflow Get-HDDInfo ([string[]]$ComputerName) {
$Result = @()
ForEach -Parallel ($Computer in $ComputerName) {
$WMIComSys = Get-WmiObject -Class win32_computerSystem -Property Name -PSComputerName $Computer
$WMIDiskDrives = Get-WmiObject -Class Win32_LogicalDisk -Filter "DeviceID = 'C:' or DeviceID = 'D:'" -PSComputerName $Computer
$tmpOBJ = New-Object psobject
$tmpOBJ | Add-Member -MemberType NoteProperty -Name "ComputerName" -Value $WMIComSys.Name
foreach ($DiskDrive in $WMIDiskDrives) {
$VolumeLetter = ($DiskDrive.deviceID).substring(0,1)
$VolumeTotalSize = "{0:N2}" -f $(($DiskDrive.Size) / 1GB)
$VolumeFreeSize = "{0:N2}" -f $(($DiskDrive.FreeSpace) / 1GB)
$VolumeName = $DiskDrive.VolumeName
# Variables outputs the correct values to C:\_tmp\test.txt
"$VolumeLetter $VolumeTotalSize $VolumeFreeSize $VolumeName" | out-file C:\_tmp\test.txt -Append
$tmpOBJ | Add-Member -MemberType NoteProperty -Name "$($VolumeLetter)_VolumeName" -Value $VolumeName
$tmpOBJ | Add-Member -MemberType NoteProperty -Name "$($VolumeLetter)_TotalSize" -Value $VolumeTotalSize
$tmpOBJ | Add-Member -MemberType NoteProperty -Name "$($VolumeLetter)_FreeSize" -Value $VolumeFreeSize
} $workflow:Result += $tmpOBJ
return $Result
Can anyone point me in the right direction?
Thanks!

I created a none-workflow version of the script:
Function Get-TestHDDInfo ([string[]]$ComputerName) {
$Result = @()
ForEach ($Computer in $ComputerName) {
$WMIComSys = Get-WmiObject -Class win32_computerSystem -Property Name -ComputerName $Computer
$WMIDiskDrives = Get-WmiObject -Class Win32_LogicalDisk -Filter "DeviceID = 'C:' or DeviceID = 'D:'" -ComputerName $Computer
$tmpOBJ = New-Object psobject
$tmpOBJ | Add-Member -MemberType NoteProperty -Name "ComputerName" -Value $WMIComSys.Name
foreach ($DiskDrive in $WMIDiskDrives) {
$VolumeLetter = ($DiskDrive.deviceID).substring(0,1)
$VolumeTotalSize = "{0:N2}" -f $(($DiskDrive.Size) / 1GB)
$VolumeFreeSize = "{0:N2}" -f $(($DiskDrive.FreeSpace) / 1GB)
$VolumeName = $DiskDrive.VolumeName
# Variables outputs the correct values to C:\_tmp\test.txt
"$VolumeLetter $VolumeTotalSize $VolumeFreeSize $VolumeName" | out-file C:\_tmp\test.txt -Append
$tmpOBJ | Add-Member -MemberType NoteProperty -Name "$($VolumeLetter)_VolumeName" -Value $VolumeName
$tmpOBJ | Add-Member -MemberType NoteProperty -Name "$($VolumeLetter)_TotalSize" -Value $VolumeTotalSize
$tmpOBJ | Add-Member -MemberType NoteProperty -Name "$($VolumeLetter)_FreeSize" -Value $VolumeFreeSize
$tmpOBJ | out-file C:\_tmp\test.txt -Append
$Result += $tmpOBJ
return $Result
This is the output:
PS C:\Windows\system32> Get-TestHDDInfo -ComputerName Comp1, Comp2
ComputerName : Comp1
C_VolumeName : OSDisk
C_TotalSize : 109,79
C_FreeSize : 21,59
D_VolumeName : VMs
D_TotalSize : 223,57
D_FreeSize : 55,76
ComputerName : Comp2
C_VolumeName : OSDisk
C_TotalSize : 59,91
C_FreeSize : 2,26
D_VolumeName : Data
D_TotalSize : 51,87
D_FreeSize : 10,14
This is how i want it to look.
