The Win32_Volume class represents an area of storage on a hard disk. The class returns local volumes that are formatted, unformatted, mounted, or offline. A volume is formatted by using a file system, such as FAT or NTFS, and might have a drive letter assigned to it. One hard disk can have multiple volumes, and volumes can span multiple physical disks. The Win32_Volume class does not support disk drive management. Windows XP and earlier: This class is not available.

Methods

Win32_Volume has 9 methods:
Method Description
AddMountPoint Adds a mount point directory for the volume.
Chkdsk Invokes the Chkdsk operation on the volume.
Defrag Defragments the volume.
DefragAnalysis Generates a fragmentation analysis for the volume.
Dismount Dismounts a volume from the file system.
ExcludeFromAutoChk Excludes volumes from the Chkdsk operation to be run at the next reboot.
Format Formats the volume.
Mount Mounts a volume to the file system.
ScheduleAutoChk Schedules Chkdsk to be run at the next reboot if the dirty bit of the volume is set.

Properties

Win32_Volume returns 41 properties:

'Access','Automount','Availability','BlockSize','Capacity','Caption','Compressed',
'ConfigManagerErrorCode','ConfigManagerUserConfig','CreationClassName','Description','DeviceID','DirtyBitSet',
'DriveLetter','DriveType','ErrorCleared','ErrorDescription','ErrorMethodology','FileSystem',
'FreeSpace','IndexingEnabled','InstallDate','Label','LastErrorCode','MaximumFileNameLength',
'Name','NumberOfBlocks','PNPDeviceID','PowerManagementCapabilities',
'PowerManagementSupported','Purpose','QuotasEnabled','QuotasIncomplete','QuotasRebuilding','SerialNumber',
'Status','StatusInfo','SupportsDiskQuotas','SupportsFileBasedCompression',
'SystemCreationClassName','SystemName'

Unless explicitly marked as writeable, all properties are read-only. Read all properties for all instances:

Get-CimInstance -ClassName Win32_Volume -Property *

Most WMI classes return one or more instances.

When Get-CimInstance returns no result, then apparently no instances of class Win32_Volume 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

UINT16

Access returns a numeric value. To translate it into a meaningful text, use any of the following approaches:

Use a PowerShell Hashtable
$Access_map = @{
Unknown media. = '0 (0x0)'
The media is readable. = '1 (0x1)'
The media is writable. = '2 (0x2)'
The media is readable and writable. = '3 (0x3)'
"Write once" media. = '4 (0x4)'
}
Use a switch statement
switch([int]$value)
{
  Unknown media. {'0 (0x0)'}
  The media is readable. {'1 (0x1)'}
  The media is writable. {'2 (0x2)'}
  The media is readable and writable. {'3 (0x3)'}
  "Write once" media. {'4 (0x4)'}
  default    {"$value"}
}
Use Enum structure
Enum EnumAccess
{
  _0_0x0   = Unknown media.
  _1_0x1   = The media is readable.
  _2_0x2   = The media is writable.
  _3_0x3   = The media is readable and writable.
  _4_0x4   = "Write once" media.
}

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.

}

#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

    Select-Object -ExpandProperty Access

# output values
$friendlyValues

# output values as comma separated list
$friendlyValues -join ', '

Use $Access_map to directly translate raw values from an instance
<# 
  this example uses a hashtable to manually translate raw numeric values 
  for property "Win32_Volume" to friendly text. This approach is ideal when
  there is just one instance to work with.

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.

Automount

BOOLEAN

If true, the volume is mounted to the file system automatically when the first I/O is issued. If false, the volume is not mounted until explicitly mounted by using the Mount method, or by adding a drive letter or mount point.

Availability

UINT16

Describes the availability and status of the device. Inherited from CIM_LogicalDevice. This can be one of the following values.

Use a switch statement inside a calculated property for Select-Object
<# 
  this example uses a switch clause to translate raw numeric 
  values for property "StatusInfo" to friendly text. The switch
  clause is embedded into a calculated property so there is
  no need to refer to external variables for translation.

  Note: to use other properties than "StatusInfo", look up the appropriate 
  translation switch clause for the property you would like to use instead.
#>

#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 "StatusInfo", 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:
#>
 
$StatusInfo = @{
  Name = 'StatusInfo'
  Expression = {
    # property is an array, so process all values
    $value = $_.StatusInfo
    
    switch([int]$value)
      {
        Other      {'1 (0x1)'}
        Unknown    {'2 (0x2)'}
        Enabled    {'3 (0x3)'}
        Disabled   {'4 (0x4)'}
        Not Applicable {'5 (0x5)'}
        default    {"$value"}
      }
      
  }  
}
#endregion define calculated property

# retrieve all instances...
Get-CimInstance -ClassName Win32_Volume | 
  # ...and output properties "Caption" and "StatusInfo". The latter is defined
  # by the hashtable in $StatusInfo:
  Select-Object -Property Caption, $StatusInfo
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_Volume", look up the appropriate 
  enum definition for the property you would like to use instead.
#>


#region define enum with value-to-text translation:
Enum EnumStatusInfo
{
  _1_0x1   = Other
  _2_0x2   = Unknown
  _3_0x3   = Enabled
  _4_0x4   = Disabled
  _5_0x5   = Not Applicable
}

#endregion define enum

# get one instance:
$instance = Get-CimInstance -Class Win32_Volume | Select-Object -First 1

<#
  IMPORTANT: this example processes only one instance to focus on
  the number-to-text type conversion. 
  
  To process all instances, replace   "Select-Object -First 1" 
  with a "Foreach-Object" loop, and use the iterator variable 
  $_ instead of $instance
#>

# query the property:
$rawValue = $instance.StatusInfo

#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 **StatusInfo** 
[EnumStatusInfo]$rawValue 

# get a comma-separated string:
[EnumStatusInfo]$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 [EnumStatusInfo]
#endregion

Enums must cover all possible values. If StatusInfo 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.

SupportsDiskQuotas

BOOLEAN

If true, the volume supports disk quotas.

Get-CimInstance -ClassName Win32_Volume | Select-Object -Property SupportsDiskQuotas

SupportsFileBasedCompression

BOOLEAN

If True, the logical disk partition supports file-based compression, such as is the case with the NTFS file system. This property is False when the Compressed property is True.

Get-CimInstance -ClassName Win32_Volume | Select-Object -Property SupportsFileBasedCompression

SystemCreationClassName

STRING

Indicates the system’s creation class name.

Get-CimInstance -ClassName Win32_Volume | Select-Object -Property SystemCreationClassName

SystemName

STRING

Indicates the system’s name.

Get-CimInstance -ClassName Win32_Volume | Select-Object -Property SystemName

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 = 'Access',
              'Automount',
              'Availability',
              'BlockSize',
              'Capacity',
              'Caption',
              'Compressed',
              'ConfigManagerErrorCode',
              'ConfigManagerUserConfig',
              'CreationClassName',
              'Description',
              'DeviceID',
              'DirtyBitSet',
              'DriveLetter',
              'DriveType',
              'ErrorCleared',
              'ErrorDescription',
              'ErrorMethodology',
              'FileSystem',
              'FreeSpace',
              'IndexingEnabled',
              'InstallDate',
              'Label',
              'LastErrorCode',
              'MaximumFileNameLength',
              'Name',
              'NumberOfBlocks',
              'PNPDeviceID',
              'PowerManagementCapabilities',
              'PowerManagementSupported',
              'Purpose',
              'QuotasEnabled',
              'QuotasIncomplete',
              'QuotasRebuilding',
              'SerialNumber',
              'Status',
              'StatusInfo',
              'SupportsDiskQuotas',
              'SupportsFileBasedCompression',
              'SystemCreationClassName',
              'SystemName'
Get-CimInstance -ClassName Win32_Volume | 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_Volume -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_Volume -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 CreationClassName, LastErrorCode, QuotasIncomplete, NumberOfBlocks FROM Win32_Volume WHERE Caption LIKE 'a%'"

Any property you did not specify is still present but empty. You might need to use Select-Object to remove all unwanted properties:

Get-CimInstance -Query "SELECT CreationClassName, LastErrorCode, QuotasIncomplete, NumberOfBlocks FROM Win32_Volume WHERE Caption LIKE 'a%'" | Select-Object -Property CreationClassName, LastErrorCode, QuotasIncomplete, NumberOfBlocks

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_Volume -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_Volume -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_Volume, 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_Volume was introduced on clients with None supported and on servers with Windows Server 2003.

Namespace

Win32_Volume 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_Volume is implemented in Vdswmi.dll and defined in Vds.mof. Both files are located in the folder C:\Windows\system32\wbem:

explorer $env:windir\system32\wbem
notepad $env:windir\system32\wbem\Vds.mof
