Question

我正在尝试获取C：\的总大小和可用空间，但是它没有追加到CSV文件中。

使用DeviceID和Devicetype尝试过，不确定哪一个是正确的

$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

这将满足我的要求。我仍然不确定您的实际问题是什么，因为您没有包括您所引用的所有代码。

我想您所指的问题是如何标识系统驱动器。我从Get-CimInstance -ClassName CIM_OperatingSystem得到了驱动器号，然后用它来过滤对Get-CimInstance -ClassName CIM_LogicalDisk的调用的结果。

我只有一个系统，因此响应全部来自该系统。 [咧嘴]

$IC_Scriptblock = {
    $CIM_ComputerSystem = Get-CimInstance -ClassName CIM_ComputerSystem
    $CIM_OperatingSystem = Get-CimInstance -ClassName CIM_OperatingSystem
    $CIM_LogicalDisk = Get-CimInstance -ClassName CIM_LogicalDisk |
        Where-Object {$_.Name -eq $CIM_OperatingSystem.SystemDrive}

    [PSCustomObject]@{
        ComputerName = $CIM_ComputerSystem.Name
        SysDrive = $CIM_OperatingSystem.SystemDrive
        SysDrive_FreeSpace_GB = '{0:N2}' -f ($CIM_LogicalDisk.FreeSpace / 1GB)
        SysDrive_FreeSpace_Pct = '{0:N0}' -f (($CIM_LogicalDisk.FreeSpace / $CIM_LogicalDisk.Size) * 100)
        SysDrive_Size_GB = '{0:N2}' -f ($CIM_LogicalDisk.Size / 1GB)

    }

$RespondingSystems = foreach ($CL_Item in $ComputerList)
