The Win32_DiskPartition WMI class represents the capabilities and management capacity of a partitioned area of a physical disk on a computer system running Windows. Example: Disk #0, Partition #1.
Methods
Win32_DiskPartition has 2 methods:
| Method | Description |
|---|---|
| Reset | Requests a reset of the logical device. |
| SetPowerState | Sets the desired power state for a logical device and when a device should be put into that state. |

Properties
Win32_DiskPartition returns 40 properties:
'Access','AdditionalAvailability','Availability','BlockSize','Bootable',
'BootPartition','Caption','ConfigManagerErrorCode','ConfigManagerUserConfig','CreationClassName',
'Description','DeviceID','DiskIndex','ErrorCleared','ErrorDescription','ErrorMethodology',
'HiddenSectors','IdentifyingDescriptions','Index','InstallDate','LastErrorCode','MaxQuiesceTime',
'Name','NumberOfBlocks','OtherIdentifyingInfo','PNPDeviceID','PowerManagementCapabilities',
'PowerManagementSupported','PowerOnHours','PrimaryPartition','Purpose','RewritePartition','Size',
'StartingOffset','Status','StatusInfo','SystemCreationClassName','SystemName','TotalPowerOnHours',
'Type'
Unless explicitly marked as writeable, all properties are read-only. Read all properties for all instances:
Get-CimInstance -ClassName Win32_DiskPartition -Property *
Most WMI classes return one or more instances.
When
Get-CimInstancereturns no result, then apparently no instances of class Win32_DiskPartition 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).
Access
Media access available.
Access returns a numeric value. To translate it into a meaningful text, use any of the following approaches:
Use a PowerShell Hashtable
$Access_map = @{
0 = 'Unknown'
1 = 'Readable'
2 = 'Writeable'
3 = 'Read/Write Supported'
4 = 'Write Once'
}
Use a switch statement
switch([int]$value)
{
0 {'Unknown'}
1 {'Readable'}
2 {'Writeable'}
3 {'Read/Write Supported'}
4 {'Write Once'}
default {"$value"}
}
Use Enum structure
Enum EnumAccess
{
Unknown = 0
Readable = 1
Writeable = 2
ReadWrite_Supported = 3
Write_Once = 4
}
Examples
Use $Access_map in a calculated property for Select-Object
<#
this example uses a hashtable to translate raw numeric values for
property "Access" to friendly text
Note: to use other properties than "Access", look up the appropriate
translation hashtable for the property you would like to use instead.
#>
#region define hashtable to translate raw values to friendly text
# Please note: this hashtable is specific for property "Access"

$Access_map = @{
0 = 'Unknown'
1 = 'Readable'
2 = 'Writeable'
3 = 'Read/Write Supported'
4 = 'Write Once'
}
#endregion define hashtable
#region define calculated property (to be used with Select-Object)
<#
a calculated property is defined by a hashtable with keys "Name" and "Expression"
"Name" defines the name of the property (in this example, it is "Access", but you can rename it to anything else)
"Expression" defines a scriptblock that calculates the content of this property
in this example, the scriptblock uses the hashtable defined earlier to translate each numeric
value to its friendly text counterpart:
#>
$Access = @{
Name = 'Access'
Expression = {
# property is an array, so process all values
$value = $_.Access
$Access_map[[int]$value]
}
}
#endregion define calculated property
# retrieve the instances, and output the properties "Caption" and "Access". The latter
# is defined by the hashtable in $Access:

# ...or dump content of property Access:
$friendlyValues = Get-CimInstance -Class Win32_DiskPartition |

Use the Enum from above to auto-translate the code values
<#
this example translates raw values by means of type conversion
the friendly names are defined as enumeration using the
keyword "enum" (PowerShell 5 or better)
The raw value(s) are translated to friendly text by
simply converting them into the enum type.
Note: to use other properties than "Win32_DiskPartition", look up the appropriate
enum definition for the property you would like to use instead.
#>
#region define enum with value-to-text translation:

with a "Foreach-Object" loop, and use the iterator variable
$_ instead of $instance
#>
# query the property:
$rawValue = $instance.Access
#region using strict type conversion
<#
Note: strict type conversion fails if the raw value is
not defined by the enum. So if the list of allowable values
was extended and the enum does not match the value,
an exception is thrown
#>
# convert the property to the enum **Access**
[EnumAccess]$rawValue
# get a comma-separated string:
[EnumAccess]$rawValue -join ','
#endregion
#region using operator "-as"
<#
Note: the operator "-as" accepts values not defined
by the enum and returns $null instead of throwing
an exception
#>
$rawValue -as [EnumAccess]
#endregion
Enums must cover all possible values. If Access returns a value that is not defined in the enum, an exception occurs. The exception reports the value that was missing in the enum. To fix, add the missing value to the enum.
AdditionalAvailability
Additional availability and status of the Device, beyond that specified in the Availability property. The Availability property denotes the primary status and availability of the Device. In some cases, this will not be sufficient to denote the complete status of the Device. In those cases, the AdditionalAvailability property can be used to provide further information. For example, a Device’s primary Availability may be Off line (value=8), but it may also be in a low power state (AdditonalAvailability value=14), or the Device could be running Diagnostics (AdditionalAvailability value=5, In Test).”
AdditionalAvailability returns a numeric value. To translate it into a meaningful text, use any of the following approaches:
Use a PowerShell Hashtable
$AdditionalAvailability_map = @{
1 = 'Other'
2 = 'Unknown'
3 = 'Running/Full Power'
4 = 'Warning'
5 = 'In Test'
6 = 'Not Applicable'
7 = 'Power Off'
8 = 'Off Line'
9 = 'Off Duty'
10 = 'Degraded'
11 = 'Not Installed'
12 = 'Install Error'
13 = 'Power Save - Unknown'
14 = 'Power Save - Low Power Mode'
15 = 'Power Save - Standby'
16 = 'Power Cycle'
17 = 'Power Save - Warning'
18 = 'Paused'
19 = 'Not Ready'
20 = 'Not Configured'
21 = 'Quiesce'
}
Use a switch statement
switch([int]$value)
{
1 {'Other'}
2 {'Unknown'}
3 {'Running/Full Power'}
4 {'Warning'}
5 {'In Test'}
6 {'Not Applicable'}

17 {'Power Save - Warning'}
18 {'Paused'}
19 {'Not Ready'}
20 {'Not Configured'}
21 {'Quiesce'}

MaxQuiesceTime
Maximum time in milliseconds, that a Device can run in a Quiesced state. A Device’s state is defined in its Availability and AdditionalAvailability properties, where Quiesced is conveyed by the value 21. What occurs at the end of the time limit is device-specific. The Device may unquiesce, may offline or take other action. A value of 0 indicates that a Device can remain quiesced indefinitely.
Note
“The MaxQuiesceTime property has been deprecated. When evaluating the use of Quiesce, it was determine that this single property is not adequate for describing when a device will automatically exit a quiescent state. In fact, the most likely scenario for a device to exit a quiescent state was determined to be based on the number of outstanding requests queued rather than on a maximum time. This will be re-evaluated and repositioned later. \n
Get-CimInstance -ClassName Win32_DiskPartition | Select-Object -Property DeviceID, MaxQuiesceTime
Name
Label by which the object is known. When subclassed, the property can be overridden to be a key property.
Get-CimInstance -ClassName Win32_DiskPartition | Select-Object -Property DeviceID, Name
NumberOfBlocks
Total number of consecutive blocks, each block the size of the value contained in the BlockSize property, which form this storage extent. Total size of the storage extent can be calculated by multiplying the value of the BlockSize property by the value of this property. If the value of BlockSize is 1, this property is the total size of the storage extent.
For more information about using uint64 values in scripts, see Scripting in WMI.
Get-CimInstance -ClassName Win32_DiskPartition | Select-Object -Property DeviceID, NumberOfBlocks
OtherIdentifyingInfo
Array that captures additional data, beyond DeviceID information, that could be used to identify a LogicalDevice. One example would be to hold the Operating System’s user friendly name for the Device in this property. Maximum length is 256.
Get-CimInstance -ClassName Win32_DiskPartition | Select-Object -Property DeviceID, OtherIdentifyingInfo
PNPDeviceID
Windows Plug and Play device identifier of the logical device.
Example: “*PNP030b”
Get-CimInstance -ClassName Win32_DiskPartition | Select-Object -Property DeviceID, PNPDeviceID
PowerManagementCapabilities
Indicates the specific power-related capabilities of the logical device. The array values, 0=”Unknown”, 1=”Not Supported” and 2=”Disabled” are self-explanatory. The value, 3=”Enabled” indicates that the power management features are currently enabled but the exact feature set is unknown or the information is unavailable. “Power Saving Modes Entered Automatically” (4) describes that a device can change its power state based on usage or other criteria. “Power State Settable” (5) indicates that the SetPowerState method is supported. “Power Cycling Supported” (6) indicates that the SetPowerState method can be invoked with the PowerState input variable set to 5 (“Power Cycle”). “Timed Power On Supported” (7) indicates that the SetPowerState method can be invoked with the PowerState input variable set to 5 (“Power Cycle”) and the Time parameter set to a specific date and time, or interval, for power-on.
PowerManagementCapabilities returns a numeric value. To translate it into a meaningful text, use any of the following approaches:
Use a PowerShell Hashtable
$PowerManagementCapabilities_map = @{
0 = 'Unknown'
1 = 'Not Supported'
2 = 'Disabled'
3 = 'Enabled'
4 = 'Power Saving Modes Entered Automatically'
5 = 'Power State Settable'
6 = 'Power Cycling Supported'
7 = 'Timed Power On Supported'
}
Use a switch statement
switch([int]$value)
{
0 {'Unknown'}
1 {'Not Supported'}
2 {'Disabled'}
3 {'Enabled'}
4 {'Power Saving Modes Entered Automatically'}
5 {'Power State Settable'}
6 {'Power Cycling Supported'}
7 {'Timed Power On Supported'}
default {"$value"}
}
Use Enum structure
Enum EnumPowerManagementCapabilities
{
Unknown = 0
Not_Supported = 1
Disabled = 2
Enabled = 3
Power_Saving_Modes_Entered_Automatically = 4
Power_State_Settable = 5
Power_Cycling_Supported = 6
Timed_Power_On_Supported = 7
}

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.

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_DiskPartition -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_DiskPartition -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 Caption, Status, PowerOnHours, SystemName FROM Win32_DiskPartition 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 Caption, Status, PowerOnHours, SystemName FROM Win32_DiskPartition WHERE Caption LIKE 'a%'" | Select-Object -Property Caption, Status, PowerOnHours, SystemName
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_DiskPartition -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_DiskPartition -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_DiskPartition, 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_DiskPartition was introduced on clients with Windows Vista and on servers with Windows Server 2008.
Namespace
Win32_DiskPartition 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_DiskPartition 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
