Description
The Clear-Disk cmdlet clears the disk by removing the partition and volume information.
If the disk contains active data volumes, then the RemoveData parameter is required as this will delete all data from the specified disk. This cmdlet will not clear OEM recovery partitions unless RemoveOEM parameter is also specified.
Examples
Example 1: Clear a blank disk
PS C:\> Clear-Disk -Number 1
This example clears disk number one only if it does not contain both data or OEM partitions.
Example 2: Clear a disk with data partitions
PS C:\> Clear-Disk -Number 1 -RemoveData
This example clears the disk if it has data partitions, but not if it also has OEM partitions.
Example 3: Clear a disk with data and OEM partitions
PS C:\> Clear-Disk -Number 1 -RemoveData -RemoveOEM
This example clears the disk regardless of whether it contains data or OEM partitions.
Parameters

-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.

Notes
- When used in Failover Cluster, cmdlets from the Storage module operate on cluster level (all servers in the cluster).
