Was recently asked to retrieve hard drive (type=3) information from a supplied list of servers for backup planning.

Following is a script used to gather this information.
Now if I could only find a way to get the file count.....

function Get-DriveInventory
{
PROCESS
{
#get drives from WMI
$drives = gwmi win32_logicaldisk -comp $_ -filter "drivetype=3"
#construct output objects
foreach ($drive in $drives)
{
$obj = New-Object psobject
$obj  Add-Member NoteProperty ComputerName $_
$obj  Add-Member NoteProperty DriveLetter $drive.deviceid
$obj  Add-Member NoteProperty VolumeName $drive.VolumeName
$free = $drive.freespace/1MB -as [int]
$obj  Add-Member NoteProperty AvailableSpace $free
$total = $drive.size/1MB -as [int]
$obj  Add-Member NoteProperty TotalSpace $total
Write-Output $obj
}
}
}

function Get-FileName
{
$computer = Read-Host "Filename of computer names?"
return $computer
}
# get the filename
$f = Get-FileName
Get-Content $f  Get-DriveInventory  Export-Csv "C:\Users\Public\Documents\DriveInventory.csv"
