Get-WmiObject -ComputerName $ip -Credential $credential -Class Win32_logicaldisk
这会让我看到“我的电脑”中的磁盘，例如。 C：，D：，E： 现在我如何获得相应的底层物理磁盘？
如果我运行以下命令
Get-WmiObject -ComputerName $ip -Credential $credential -Class win32_diskdrive
我得到磁盘0，磁盘1，磁盘2
那么如何找出哪个逻辑磁盘在哪个物理磁盘上？
另一个问题是如何找出卷号？如果我运行diskpart并执行“list volume”，我会得到以下输出
Volume ### Ltr Label Fs Type Size Status Info
---------- --- ----------- ----- ---------- ------- --------- --------
Volume 2 C NTFS Partition 59 GB Healthy Boot
...
如何找出逻辑磁盘C：是第2卷？
最好的问候，Primoz。

试试这个
Get-WMIObject Win32_LogicalDisk | Foreach-Object {
Get-WmiObject -Query "Associators of {Win32_LogicalDisk.DeviceID='$($_.DeviceID)'} WHERE ResultRole=Antecedent"
} | Format-Table
这为您提供了WIn32_logicalDisk的相关实例，其中Win32_LogicalDisk是关系中的依赖实体。因此，您将获得Win32_DiskDrive实例。

这是我创建的完整脚本，用于列出逻辑磁盘，分区和分区偏移量，以检查磁盘对齐问题。 （来源：我的博客http://sev17.com/2009/02/disk-alignment-partitioning-the-good-the-bad-the-ok-and-the-not-so-ugly/）

如果您不关心 mountpoint卷，那么WMI关系的其他答案是好的，因为WMI没有可能直接将mountpoint卷与分区或磁盘相关联。
但是有一个注册表项可以帮助你弄清楚一些可以帮助你建立连接的信息，就像windows一样：
function getVolumeInformation{
param($hostName, $credential)
$volumeInformation = getVolumeInformation -computerName $hostName -credential $credential
$WMIRegistryMountedDeviceInfo = WMIRegistryMountedDeviceInfo -computerName $hostName -Credential $credential
foreach($volumeSerial in $volumeInformation.keys){
if($WMIRegistryMountedDeviceInfo.containsKey($volumeSerial)){
$volumeInformation[$volumeSerial]["diskPartitionStartingOffset"]=$WMIRegistryMountedDeviceInfo[$volumeSerial].diskPartitionStartingOffset
$volumeInformation[$volumeSerial]["diskDriveSignature"]=$WMIRegistryMountedDeviceInfo[$volumeSerial].diskDriveSignature
$volumeInformation[$volumeSerial]["wmiValueRegistry"]=$WMIRegistryMountedDeviceInfo[$volumeSerial].wmiValue
}
}
return $volumeInformation
}
function getWMIVolumeInformation{
param($computerName, $credential)
$diskToVolumeAssociation = @{}
$regexGetVolumeSerial = ".*Volume{(.*)}.*"
$wmiVolumes = $null
$wmiVolumes = Get-WmiObject Win32_Volume -Credential $credential -ComputerName $computerName -filter "DriveType != 5" -ErrorVariable errorWMIVolume -ErrorAction SilentlyContinue
$volumeInfo = @{}
$wmiVolumes | Foreach-Object {
$wmiVolume = $_
if($wmiVolume.DeviceID -match $regexGetVolumeSerial){
$wmiVolumeSerial = $Matches[1]
$volumeInfo[$wmiVolumeSerial] = @{}
$volumeInfo[$wmiVolumeSerial]["wmiInfo"] = $wmiVolume
$volumeInfo[$wmiVolumeSerial]["volumeDirectoryName"] = $wmiVolume.Name
$volumeInfo[$wmiVolumeSerial]["label"] = $wmiVolume.label
$volumeInfo[$wmiVolumeSerial]["serial"] = $wmiVolumeSerial
$volumeInfo[$wmiVolumeSerial]["capacity"] = $wmiVolume.Capacity
$volumeInfo[$wmiVolumeSerial]["freeSpace"] = $wmiVolume.FreeSpace
}
}
return $volumeInfo
}
function WMIRegistryMountedDeviceInfo{
param($computerName, $mycreds)
$MountPointRegistryInformation = @{}
$hklm = 2147483650
$registryKeyMountedDevices = "SYSTEM\MountedDevices"
$regexMountPoint = ".*{(.*)}.*"
$wmi = get-wmiobject -list "StdRegProv" -namespace root\default -computername $computerName -credential $mycreds
$wmiMountedDeviceKey = ($wmi.EnumValues($hklm,$registryKeyMountedDevices))
foreach($mountedDeviceRegistryName in $wmiMountedDeviceKey.sNames){
if($mountedDeviceRegistryName -match $regexMountPoint){
$wmiValue = ($wmi.GetBinaryValue($hklm,$registryKeyMountedDevices,$mountedDeviceRegistryName))
if($wmiValue.uValue.Count -eq 12){
$diskDriveSignature = [bitconverter]::ToUInt32($wmiValue.uValue[0..3],0)
$diskPartitionStartingOffset = [bitconverter]::ToUInt64($wmiValue.uValue[4..11],0)
$MountPointRegistryInformation[$Matches[1]]=@{"serial"=$Matches[1];
"mountedDeviceRegistryName"=$mountedDeviceRegistryName;
"diskDriveSignature"=$diskDriveSignature;
"diskPartitionStartingOffset"=$diskPartitionStartingOffset;
"wmiValue"=$wmiValue.uValue}
}
}
}
return $MountPointRegistryInformation
}
此代码应该为每个签名返回一个哈希表，其中包含与mountedDevice关联的磁盘的磁盘驱动器签名。它还返回DiskPartitionStartingOffset，它与与mountedDevice相关联的partition.StartingOffset相同。
如果你想自己编写代码，这个注册表SYSTEM \ MountedDevices值的前4个字节是磁盘驱动器签名，但要注意little-endian。接下来的8个字节是PartitionStartingOffset。
使用此信息，您可以使用WMI获取磁盘驱动器信息并将所有内容插入到一起，以便获得与您拥有的所有物理驱动器相关的所有卷，而不管它们是如何安装的。
这对跨区音量不起作用。
在那种注册表中玩非常小心。

检查Win32_LogicalDisktoPartition这将为您提供逻辑磁盘到Totecedent中该磁盘上的物理磁盘和分区的映射。只获取每个磁盘驱动器的标签
gwmi win32_volume | select name,label

这是另一种使用内核的替代方案。 Microsoft建议再次强调但它已经证明可以非常有效地捕获跨越的卷，挂载点和其他卷类型信息，以帮助关联磁盘和卷。
