Powershell：如何结合 2 个命令的输出将磁盘字母与磁盘 MediaType 相关联？

Question

我正在使用以下命令获取磁盘信息：

get-ciminstance -ClassName Win32_LogicalDisk

问题是，它不包含MediaType 属性（HDD、SSD 或分别为数字形式 4、3）。

我想我需要将它与另一个命令结合（关联），例如：

• Get-PhysicalDisk 或
• Get-WmiObject -Class MSFT_PhysicalDisk -Namespace root\Microsoft\Windows\Storage

我从 Node.js 调用这些命令，因此我可以运行单独的命令并在之后组合结果。它不必是 1 个命令。我只是不确定如何关联它们，因为 Powershell API 不一致：

这个返回数字

(Get-WmiObject -Class MSFT_PhysicalDisk -Namespace root\Microsoft\Windows\Storage).DeviceID

这个返回驱动器号

(get-ciminstance -ClassName Win32_LogicalDisk).DeviceID

我在另一个thread 中找到了这段代码，但我不确定如何在其中添加MediaType 属性：

Get-WmiObject Win32_DiskDrive | ForEach-Object {
  $disk = $_
  $partitions = "ASSOCIATORS OF " +
                "{Win32_DiskDrive.DeviceID='$($disk.DeviceID)'} " +
                "WHERE AssocClass = Win32_DiskDriveToDiskPartition"
  Get-WmiObject -Query $partitions | ForEach-Object {
    $partition = $_
    $drives = "ASSOCIATORS OF " +
              "{Win32_DiskPartition.DeviceID='$($partition.DeviceID)'} " +
              "WHERE AssocClass = Win32_LogicalDiskToPartition"
    Get-WmiObject -Query $drives | ForEach-Object {
      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 1

我不知道是否有更复杂的方法，但我认为它提供了您期望的结果。

$PhysicalDiskList = 
    Get-PhysicalDisk
$LogicalDiskList = 
    Get-CimInstance -ClassName CIM_LogicalDisk | 
        Where-Object -Property 'DriveType' -EQ -Value 3
$Result = 
foreach ($LogicalDisk in $LogicalDiskList) {
    $DiskPartition = 
        Get-CimAssociatedInstance -InputObject $LogicalDisk -ResultClass CIM_DiskPartition
    $PhysicalDisk = 
        $PhysicalDiskList | 
            Where-Object -Property 'DeviceID' -EQ -Value $DiskPartition.DiskIndex
    [PSCustomObject]@{
        DriveLetter = $LogicalDisk.DeviceID
        VolumeName  = $LogicalDisk.VolumeName
        Size        = $LogicalDisk.Size
        FreeSpace   = $LogicalDisk.FreeSpace
        DriveModel  = $PhysicalDisk.FriendlyName
        MediaType   = $PhysicalDisk.MediaType
    }
}

$Result | 
    Format-Table -AutoSize

它在我的系统上返回以下内容：

DriveLetter VolumeName          Size    FreeSpace DriveModel                 MediaType
----------- ----------          ----    --------- ----------                 ---------
C:          System      254493077504  49397727232 SAMSUNG MZNTY256HDHP-000L7 SSD
D:          Data       1000067821568 643155914752 WDC WD10SPCX-08S8TT0       HDD

在获取 mediatype 和其他属性方面，我的结果好坏参半。一些系统返回实际值，而另一些系统则返回整数。这是我的脚本中的一个 sn-p，可以帮助您解决这个问题。

Get-CimInstance Win32_Diskdrive -Filter "Partitions>0" | ForEach-Object {
    $disk = Get-CimInstance -ClassName MSFT_PhysicalDisk -Namespace root\Microsoft\Windows\Storage -Filter "SerialNumber='$($_.SerialNumber.trim())'"

    foreach($partition in $_ | Get-CimAssociatedInstance -ResultClassName Win32_DiskPartition){
        foreach($logicaldisk in $partition | Get-CimAssociatedInstance -ResultClassName Win32_LogicalDisk){
            [PSCustomObject]@{
                Disk          = $_.DeviceID
                DiskModel     = $_.Model
                DiskSize      = $_.Size
                HealthStatus  = $disk.HealthStatus
                BusType       = $disk.BusType
                MediaType     = "{0} ({1})" -f $_.MediaType,$disk.MediaType
                Partition     = $partition.Name
                PartitionSize = $partition.Size
                VolumeName    = $logicaldisk.VolumeName
                DriveLetter   = $logicaldisk.DeviceID
                VolumeSize    = $logicaldisk.Size
                FreeSpace     = $logicaldisk.FreeSpace
            }
        }
    }
}

在返回代码的时候，可以改为运行。

$mediatypelist = @{
    '0' = 'Unspecified'
    '3' = 'HDD'
    '4' = 'SSD'
    '5' = 'SCM'
}

$healthstatuslist = @{
    '0' = 'Healthy'
    '1' = 'Warning'
    '2' = 'Unhealthy'
    '5' = 'Unknown'
}

$bustypelist = @{
    '0' = 'Unknown'
    '1' = 'SCSI'
    '2' = 'ATAPI'
    '3' = 'ATA'
    '4' = 'IEEE 1394'
    '5' = 'SSA'
    '6' = 'Fibre Channel'
    '7' = 'USB'
    '8' = 'RAID'
    '9' = 'iSCSI'
    '10' = 'Serial Attached SCSI (SAS)'
    '11' = 'Serial ATA (SATA)'
    '12' = 'Secure Digital (SD)'
    '13' = 'Multimedia Card (MMC)'
    '14' = 'This value is reserved for system use.'
    '15' = 'File-Backed Virtual'
    '16' = 'Storage Spaces'
    '17' = 'NVMe'
    '18' = 'This value is reserved for system use.'
}

Get-CimInstance Win32_Diskdrive -Filter "Partitions>0" | ForEach-Object {
    $disk = Get-CimInstance -ClassName MSFT_PhysicalDisk -Namespace root\Microsoft\Windows\Storage -Filter "SerialNumber='$($_.SerialNumber.trim())'"

    foreach($partition in $_ | Get-CimAssociatedInstance -ResultClassName Win32_DiskPartition){
        foreach($logicaldisk in $partition | Get-CimAssociatedInstance -ResultClassName Win32_LogicalDisk){
            [PSCustomObject]@{
                Disk          = $_.DeviceID
                DiskModel     = $_.Model
                DiskSize      = $_.Size
                HealthStatus  = $healthstatuslist["$($disk.HealthStatus)"]
                BusType       = $bustypelist["$($disk.BusType)"]
                MediaType     = "{0} ({1})" -f $_.MediaType,$mediatypelist["$($disk.MediaType)"]
                Partition     = $partition.Name
                PartitionSize = $partition.Size
                VolumeName    = $logicaldisk.VolumeName
                DriveLetter   = $logicaldisk.DeviceID
                VolumeSize    = $logicaldisk.Size
                FreeSpace     = $logicaldisk.FreeSpace
            }
        }
    }
}
