Question

我有此查询扫描所有逻辑磁盘信息：

Write-Host "Drive information for $env:ComputerName"

Get-WmiObject -Class Win32_LogicalDisk |
    Where-Object {$_.DriveType -ne 5} |
    Sort-Object -Property Name | 
    Select-Object Name, VolumeName, VolumeSerialNumber,SerialNumber, FileSystem, Description, VolumeDirty, `
        @{"Label"="DiskSize(GB)";"Expression"={"{0:N}" -f ($_.Size/1GB) -as [float]}}, `
        @{"Label"="FreeSpace(GB)";"Expression"={"{0:N}" -f ($_.FreeSpace/1GB) -as [float]}}, `
        @{"Label"="%Free";"Expression"={"{0:N}" -f ($_.FreeSpace/$_.Size*100) -as [float]}} |
    Format-Table -AutoSize

The output is：

enter image description here

但是 - 我在物理磁盘信息及其分区/卷信息之后：

所以 - 对于物理磁盘我有这个命令：

Get-Disk

Result：

问题：

我想在这两个命令之间进行组合。我想在每个磁盘下面看到磁盘，和 - 它的逻辑磁盘信息：

磁盘编号1：....（info）
>其逻辑磁盘信息.....
磁盘编号2：....（info）
>它的逻辑磁盘信息.....
磁盘编号3：....（info）
>它的逻辑磁盘信息.....
等...

如何在这两个查询之间进行组合？

Answer 1

您需要查询多个WMI类以获取所需的所有信息。

Win32_DiskDrive为您提供有关物理磁盘的信息。
Win32_DiskPartition为您提供有关物理磁盘上分区的信息。
Win32_LogicalDisk为您提供有关分区内文件系统的信息。

可以使用Win32_DiskDriveToDiskPartition类将分区映射到其磁盘，并且可以通过Win32_LogicalDiskToPartition类将驱动器映射到其分区。

Get-WmiObject Win32_DiskDrive | % {
  $disk = $_
  $partitions = "ASSOCIATORS OF " +
                "{Win32_DiskDrive.DeviceID='$($disk.DeviceID)'} " +
                "WHERE AssocClass = Win32_DiskDriveToDiskPartition"
  Get-WmiObject -Query $partitions | % {
    $partition = $_
    $drives = "ASSOCIATORS OF " +
              "{Win32_DiskPartition.DeviceID='$($partition.DeviceID)'} " +
              "WHERE AssocClass = Win32_LogicalDiskToPartition"
    Get-WmiObject -Query $drives | % {
      New-Object -Type PSCustomObject -Property @{
        Disk        = $disk.DeviceID
        DiskSize    = $disk.Size
        DiskModel   = $disk.Model
        Partition   = $partition.Name
        RawSize     = $partition.Size
        DriveLetter = $_.DeviceID
        VolumeName  = $_.VolumeName
        Size        = $_.Size
        FreeSpace   = $_.FreeSpace
      }
    }
  }
}

Answer 2

这样怎么样...

Get-CimInstance Win32_Diskdrive -PipelineVariable disk |
Get-CimAssociatedInstance -ResultClassName Win32_DiskPartition -PipelineVariable partition |
Get-CimAssociatedInstance -ResultClassName Win32_LogicalDisk |
Select-Object @{n='Disk';e={$disk.deviceid}},
@{n='DiskSize';e={$disk.size}},
@{n='DiskModel';e={$disk.model}},
@{n='Partition';e={$partition.name}},
@{n='RawSize';e={$partition.size}},
@{n='DriveLetter';e={$_.DeviceID}},
VolumeName,Size,FreeSpace

受 js2010 的启发，有一些改进：

例如，Manufacturer 字段在从 Win32_DiskDrive 实例检索时似乎有一些占位符值，但在使用 Get-Disk commandlet 时具有正确的值。

function Get-Drive {

  foreach($disk in Get-CimInstance Win32_Diskdrive) {

    $diskMetadata = Get-Disk | Where-Object { $_.Number -eq $disk.Index } | Select-Object -First 1

    $partitions = Get-CimAssociatedInstance -ResultClassName Win32_DiskPartition -InputObject $disk

    foreach($partition in $partitions) {

      $drives = Get-CimAssociatedInstance -ResultClassName Win32_LogicalDisk -InputObject $partition

      foreach($drive in $drives) {

        $totalSpace = [math]::Round($drive.Size / 1GB, 3)
        $freeSpace  = [math]::Round($drive.FreeSpace / 1GB, 3)
        $usedSpace  = [math]::Round($totalSpace - $freeSpace, 3)

        $volume     = Get-Volume |
                      Where-Object { $_.DriveLetter -eq $drive.DeviceID.Trim(":") } |
                      Select-Object -First 1

        [PSCustomObject] @{
                            DriveLetter   = $drive.DeviceID
                            Number        = $disk.Index

                            Label         = $volume.FileSystemLabel
                            Manufacturer  = $diskMetadata.Manufacturer
                            Model         = $diskMetadata.Model
                            SerialNumber  = $diskMetadata.SerialNumber.Trim() 
                            Name          = $disk.Caption

                            FileSystem    = $volume.FileSystem
                            PartitionKind = $diskMetadata.PartitionStyle

                            TotalSpace    = $totalSpace
                            FreeSpace     = $freeSpace
                            UsedSpace     = $usedSpace

                            Drive         = $drive
                            Partition     = $partition
                            Disk          = $disk
        }

      }
    }
  }
}

示例用法：

Get-Drive | Format-List
Get-Drive | Where-Object { $_.DriveLetter -eq 'G:' }

输出：

DriveLetter   : G:
Number        : 5
Label         : SE-LXY2-298GB
Manufacturer  : Seagate
Model         : FreeAgent Go
SerialNumber  : 2GE45CK1
Name          : Seagate FreeAgent Go USB Device
FileSystem    : NTFS
PartitionKind : MBR
TotalSpace    : 298.089
FreeSpace     : 297.865
UsedSpace     : 0.224
Drive         : Win32_LogicalDisk: G: (DeviceID = "G:")
Partition     : Win32_DiskPartition: Disk #5, Partition #0 (DeviceID = "Disk #5, Partition #0")
Disk          : Win32_DiskDrive: Seagate FreeAgent Go USB Device (DeviceID = "\\.\PHYSICALDRIVE5")

Answer 4

我是这样做的：

[String]（[Math] :: Round（$ _。尺寸/ 1GB，2））+＆＃39; GB＆＃39;

在PowerShell中结合“Get-Disk”信息和“LogicalDisk”信息？
