Description

The Get-Partition cmdlet returns one or more Partition objects depending on the specified criteria. This cmdlet will return a Volume object or a set of Volume objects given parameters to be used to uniquely identify a volume, or parameters to identify a set of volumes that meet the given set of criteria.

Examples

Example 1

PS C:\>Get-Partition

This example return all partitions, on all disks.

Example 2

PS C:\>Get-Partition -DiskNumber 5
Disk Number: 5 
 
PartitionNumber  DriveLetter Offset                                        Size Type 
---------------  ----------- ------                                        ---- ---- 
1                H           1048576                                  298.09 GB IFS

This example return all partitions on disk 5.

Example 3

PS C:\>Get-Partition -DriveLetter C
Disk Number: 0 
 
PartitionNumber  DriveLetter Offset                                        Size Type 
---------------  ----------- ------                                        ---- ---- 
2                C           368050176                                465.42 GB IFS

This example partition associated with the volume for drive letter C.

Example 4

PS C:\>Get-Partition | Where-Object -FilterScript {$_.Type -Eq "Basic"}

This example returns only the basic partitions on all disks.

Required Parameters

-DiskId

Specifies an ID used to identify a disk in the system.

Type:String[]
Aliases:DiskPath
Position:Named
Default value:None
Accept pipeline input:True (ByPropertyName)
Accept wildcard characters:False

Optional Parameters

-AsJob

Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete.

Type:SwitchParameter
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-CimSession

Runs the cmdlet in a remote session or on a remote computer. Enter a computer name or a session object, such as the output of a New-CimSession or Get-CimSession cmdlet. The default is the current session on the local computer.

Type:CimSession[]
Aliases:Session
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-Disk

Accepts a Disk object as input. The Disk CIM object is exposed by the Get-Disk cmdlet.

Type:CimInstance
Position:Named
Default value:None
Accept pipeline input:True (ByValue)
Accept wildcard characters:False
-DiskNumber

Specifies an array of disk numbers.

Type:UInt32[]
Position:0
Default value:None
Accept pipeline input:True (ByPropertyName)
Accept wildcard characters:False
-DriveLetter

Specifies a letter used to identify a drive or volume in the system. Specifically the drive on which the partition resides.

Type:Char[]
Position:Named
Default value:None
Accept pipeline input:True (ByPropertyName)
Accept wildcard characters:False
-Offset

Specifies the starting offset, in bytes.

Type:UInt64[]
Position:Named
Default value:None
Accept pipeline input:True (ByPropertyName)
Accept wildcard characters:False
-PartitionNumber

Specifies the number of the partition.

Type:UInt32[]
Aliases:Number
Position:1
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-StorageSubSystem

Specifies the storage subsystem from which to get paritions. To obtain a StorageSubsystem object, use the Get-StorageSubSystem cmdlet.

Type:CimInstance
Position:Named
Default value:None
Accept pipeline input:True (ByValue)
Accept wildcard characters:False
-ThrottleLimit

Specifies the maximum number of concurrent operations that can be established to run the cmdlet. If this parameter is omitted or a value of 0 is entered, then Windows PowerShell® calculates an optimum throttle limit for the cmdlet based on the number of CIM cmdlets that are running on the computer. The throttle limit applies only to the current cmdlet, not to the session or to the computer.

Type:Int32
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-UniqueId

Specifies the ID of the partition to get.

Type:String[]
Position:Named
Default value:None
Accept pipeline input:True (ByPropertyName)
Accept wildcard characters:False
-Volume

Accepts a Volume object as input. The Volume CIM object is exposed by the Get-Volume cmdlet.

Type:CimInstance
Position:Named
Default value:None
Accept pipeline input:True (ByValue)
Accept wildcard characters:False

Inputs

Microsoft.Management.Infrastructure.CimInstance#ROOT/Microsoft/Windows/Storage/MSFT_Disk

The Microsoft.Management.Infrastructure.CimInstance object is a wrapper class that displays Windows Management Instrumentation (WMI) objects. The path after the pound sign (#) provides the namespace and class name for the underlying WMI object.

Inputs
