Parameters

-AsJob: Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete.
-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.
-Disk: Accepts a Disk object as input. The Disk CIM object is exposed by the Get-Disk cmdlet.
-DiskId (required): Specifies an ID used to identify a disk in the system.
-DiskNumber: Specifies an array of disk numbers.
-DriveLetter: Specifies a letter used to identify a drive or volume in the system. Specifically the drive on which the partition resides.
-Offset: Specifies the starting offset, in bytes.
-PartitionNumber: Specifies the number of the partition.
-StorageSubSystem: Specifies the storage subsystem from which to get partitions. To obtain a StorageSubsystem object, use the Get-StorageSubSystem cmdlet.
-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.
-UniqueId: Specifies the ID of the partition to get.
-Volume: Accepts a Volume object as input. The Volume CIM object is exposed by the Get-Volume cmdlet.

Prerequisites

Windows with the Storage module and the Windows feature or management tools that provide it. Confirm target connectivity and version compatibility using the linked Microsoft reference.
