The Win32_LogicalDiskToPartition association WMI class relates a logical disk drive and the disk partition it resides on.
Methods
Win32_LogicalDiskToPartition has no methods.
Properties
Win32_LogicalDiskToPartition returns 4 properties:
'Antecedent','Dependent','EndingAddress','StartingAddress'
Unless explicitly marked as writeable, all properties are read-only. Read all properties for all instances:
Get-CimInstance -ClassName Win32_LogicalDiskToPartition -Property *
Most WMI classes return one or more instances.
When
Get-CimInstancereturns no result, then apparently no instances of class Win32_LogicalDiskToPartition exist. This is normal behavior.Either the class is not implemented on your system (may be deprecated or due to missing drivers, i.e. CIM_VideoControllerResolution), or there are simply no physical representations of this class currently available (i.e. Win32_TapeDrive).
Antecedent
KEY PROPERTY WIN32_DISKPARTITION
Reference to the instance representing the properties of a disk partition where the logical disk resides.
Get-CimInstance -ClassName Win32_LogicalDiskToPartition | Select-Object -Property Antecedent, Dependent
Dependent
KEY PROPERTY WIN32_LOGICALDISK
Reference to the instance representing the properties of a logical disk that resides on a physical disk partition.
Get-CimInstance -ClassName Win32_LogicalDiskToPartition | Select-Object -Property Antecedent, Dependent
EndingAddress
Indicates the end of the high-level extent in lower-level storage. This property is useful when mapping non-contiguous extents into a higher-level grouping.
For more information about using uint64 values in scripts, see Scripting in WMI.
Get-CimInstance -ClassName Win32_LogicalDiskToPartition | Select-Object -Property Antecedent, Dependent, EndingAddress
StartingAddress
Indicates the beginning of the high-level extent in lower-level storage.
For more information about using uint64 values in scripts, see Scripting in WMI.
Get-CimInstance -ClassName Win32_LogicalDiskToPartition | Select-Object -Property Antecedent, Dependent, StartingAddress

Selecting Properties
To select only some properties, pipe the results to Select-Object -Property a,b,c with a comma-separated list of the properties you require. Wildcards are permitted.
Get-CimInstance always returns all properties but only retrieves the ones that you specify. All other properties are empty but still present. That’s why you need to pipe the results into Select-Object if you want to limit the visible properties, i.e. for reporting.
Selecting Properties
The code below lists all available properties. Remove the ones you do not need:
$properties = 'Antecedent',
'Dependent',
'EndingAddress',
'StartingAddress'
Get-CimInstance -ClassName Win32_LogicalDiskToPartition | Select-Object -Property $properties
Limiting Network Bandwidth
If you work remotely, it makes sense to limit network bandwidth by filtering the properties on the server side, too:
Get-CimInstance -Class Win32_LogicalDiskToPartition -Property $property |
Select-Object -Property $property
Selecting Instances
To select some instances, use Get-CimInstance and a WMI Query. The wildcard character in WMI Queries is % (and not “*”).
The parameter -Filter runs a simple query.
Listing all instances where the property Caption starts with “A”
Get-CimInstance -Class Win32_LogicalDiskToPartition -Filter 'Caption LIKE "a%"'
Using a WQL Query
The parameter -Query uses a query similar to SQL and combines the parameters -Filter and -Property. This returns all instances where the property Caption starts with “A”, and returns the properties specified:
Get-CimInstance -Query "SELECT Antecedent, Dependent, EndingAddress, StartingAddress FROM Win32_LogicalDiskToPartition WHERE Caption LIKE 'a%'"
Any property you did not specify is still present but empty. You might need to use
Select-Objectto remove all unwanted properties:Get-CimInstance -Query "SELECT Antecedent, Dependent, EndingAddress, StartingAddress FROM Win32_LogicalDiskToPartition WHERE Caption LIKE 'a%'" | Select-Object -Property Antecedent, Dependent, EndingAddress, StartingAddress
Accessing Remote Computers
To access remote systems, you need to have proper permissions. User the parameter -ComputerName to access one or more remote systems.
Authenticating as Current User
# one or more computer names or IP addresses:
$list = 'server1', 'server2'
# authenticate with your current identity:
$result = Get-CimInstance -ClassName Win32_LogicalDiskToPartition -ComputerName $list
$result
Authenticating as Different User
Use a CIMSession object to authenticate with a new identity:
# one or more computer names or IP addresses:
$list = 'server1', 'server2'
# authenticate with a different identity:
$cred = Get-Credential -Message 'Authenticate to retrieve WMI information:'
$session = New-CimSession -ComputerName $list -Credential $cred
$result = Get-CimInstance Win32_LogicalDiskToPartition -CimSession $session
# remove the session after use (if you do not plan to re-use it later)
Remove-CimSession -CimSession $session
$result

Requirements
To use Win32_LogicalDiskToPartition, the following requirements apply:
PowerShell
Get-CimInstance was introduced with PowerShell Version 3.0, which in turn was introduced on clients with Windows 8 and on servers with Windows Server 2012.
If necessary, update Windows PowerShell to Windows PowerShell 5.1, or install PowerShell 7 side-by-side.
Operating System
Win32_LogicalDiskToPartition was introduced on clients with Windows Vista and on servers with Windows Server 2008.
Namespace
Win32_LogicalDiskToPartition lives in the Namespace Root/CIMV2. This is the default namespace. There is no need to use the -Namespace parameter in Get-CimInstance.
Implementation
Win32_LogicalDiskToPartition is implemented in CIMWin32.dll and defined in CIMWin32.mof. Both files are located in the folder C:\Windows\system32\wbem:
explorer $env:windir\system32\wbem
notepad $env:windir\system32\wbem\CIMWin32.mof
