Powershell Script to check C: drive capacity and write to CSV file - powershell

Question

I'm trying to get C:\ total size and the free space, but it is not appending to CSV file.
Tried using DeviceID and Devicetype, not sure which one is true
$path="C:\server" #Split-Path $MyInvocation.MyCommand.path 
#$cred= get-credential 
$Computers = get-content "$path\computers.txt"   
foreach ($Computer in $Computers)  
{  
$Disks = Get-wmiobject  Win32_LogicalDisk -computername $Computer
}

Answer 1

this will do what i think you want. i am still unsure what your actual problem is since you did not include all the code that you referred to.
i THINK the problem you were referring to was how to ID the system drive. i got the drive letter from Get-CimInstance -ClassName CIM_OperatingSystem and then used that to filter the results from a call to Get-CimInstance -ClassName CIM_LogicalDisk.
i've only one system, so the responses are all from that one. [grin]
