Powershell Format Arrays to two dimensional Arrays - arrays

Question

i had a problem a few days ago where my script that is supposed to extract all hostnames from an AD OU and then check for the space used and free space on disks for every single host. Since this is the first time i do something with powershell i ran into many problems. The Problem that i got now is that the script cant find the hostnames listed in an array. I think i found out why it wont work because it uses the wrong hostname.
Error message i get for every hostname:
Write-Warning : Es wurde kein Positionsparameter gefunden, der das Argument "#{Name=BUCHHOLZMVZ}" akzeptiert.
In Zeile:16 Zeichen:5
+ Write-Warning "Server " $server "nicht erreichbar"
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidArgument: (:) [Write-Warning], ParameterBindingException
+ FullyQualifiedErrorId : PositionalParameterNotFound,Microsoft.PowerShell.Commands.WriteWarningCommand
When i only use the command to get all hostnames of all servers i get:
Name
----
someserver
someserver1
someserver2
(and so on...)
Here is the script:
$servers = Get-ADComputer -Filter * -SearchBase "OU=ServerOU, DC=somedomain, DC=somedomain, DC=somedomain" | Select-Object Name
$allDisks = foreach ($server in $servers)
{
try {
Get-WmiObject Win32_LogicalDisk -ComputerName $server -Filter DriveType=3 -ErrorAction Stop |
Select-Object #{'Name'='ComputerName'; 'Expression'={$server}},
DeviceID,
#{'Name'='Size'; 'Expression'={[math]::truncate($_.size / 1GB)}},
#{'Name'='Freespace'; 'Expression'={[math]::truncate($_.freespace / 1GB)}}
}
catch {
Write-Warning "Server " $server "nicht erreichbar"
Continue
}
}
$allDisks |Export-Csv C:\Servers.csv -NoTypeInformation

Use the following for your first line:
$servers = Get-ADComputer -Filter * -SearchBase "OU=ServerOU, DC=somedomain, DC=somedomain, DC=somedomain" |
Select-Object -Expand Name
Using Select-Object without -Expand or -ExpandProperty outputs an object that contains properties and values. If you only want to output values of the selected properties you must use -Expand or member access ($servers.Name).
