PowerShell脚本将所有磁盘和驱动器详细信息（包括安装点）以及名称，可用空间和容量导出到CSV文件

Question

Is there a way to get PowerShell script to export all disk, drive and mount point details (including name, freespace and capacity) to a csv file.

$serverlist = Get-Content .\servers.txt
Write-Output "disk details"
foreach ($server in $serverlist) {
    $a = Get-WmiObject Win32_Volume -ComputerName $server
    foreach ($drive in $a) {
        $b = $a.Name
        $c = $a.Label
        $d = $a.FreeSpace
        $e = $a.Capacity
    }
    Write-Output "$server, $b, $c, $d, $e " | Out-File C:\EAM\ram.csv  -Append
} 

The CSV file should be in the below format:

Server Name       Disk Name          FreeSpace        Capacity
Server1            Disk1             X GB              Y GB
                   Disk2             A GB              B GB
Server 2          Disk 1             C GB              D GB
                  Disk 5             Z GB              N GB
...               ...                ...               ...

You're overcomplicating things. This will do what you want:

$serverlist = Get-Content .\servers.txt
Get-WmiObject Win32_Volume -Computer $serverlist |
    Select-Object __SERVER, Name, Label, FreeSpace, Capacity |
    Export-Csv 'C:\output.csv' -NoType

If you need particular column titles instead of the regular property names or values in a particular format use calculated properties to change that:

Get-WmiObject Win32_Volume -Computer $serverlist |
    Select-Object @{n='Server Name';e={$_.__SERVER}}, @{n='Drive';e={$_.Name}},
        @{n='Disk Name';e={$_.Label}},
        @{n='FreeSpace';e={'{0} GB' -f [int]($_.FreeSpace/1GB)}},
        @{n='Capacity';e={'{0} GB' -f [int]($_.Capacity/1GB)}} |
    Export-Csv 'C:\output.csv' -NoType
