Description
The Initialize-Disk cmdlet initializes a Disk object with the RAW partition style to either the MBR or GPT partition styles. The default partition style is GPT. Disks must be initialized before they can be formatted and used to store data.
Examples
Example 1: Initialize a disk using default values
PS C:\>Initialize-Disk -Number 1
This example initializes the first disk in the computer (disk number 1), using the default values, which initializes the disk using the GPT partition style.
Example 2: Initialize a disk using the MBR partition style
PS C:\> Initialize-Disk -Number 1 -PartitionStyle MBR
This example initializes a disk using the MBR partition style.
Example 3: Initialize a virtual disk
PS C:\>Initialize-Disk -VirtualDisk (Get-VirtualDisk -FriendlyName UserData)
This example uses the VirtualDisk parameter with the Get-VirtualDisk cmdlet to get a virtual disk with the friendly name UserData, and initialize the Disk object associated with the virtual disk.
Parameters
-AsJob
Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete.

Parameter sets
InputObject (cdxml)
| Position: | Named |
| Mandatory: | True |
| Value from pipeline: | True |

-Number
Specifies the disk number of the disk to initialize.
Parameter properties
| Type: | UInt32[] |

| Value from pipeline by property name: | True |
| Value from remaining arguments: | False |
-PartitionStyle
Specifies the type of the partition.
The acceptable values for this parameter are: MBR or GPT.
The disk must be set to read-write (IsReadOnly $false ) before this cmdlet will work.
Parameter properties
| Type: | PartitionStyle |
| Default value: | None |
| Accepted values: | Unknown, MBR, GPT |
| Supports wildcards: | False |

| Value from remaining arguments: | False |
-PassThru
Sends items from the interactive window down the pipeline as input to other cmdlets. By default, this cmdlet does not generate any output.
To send items from the interactive window down the pipeline, click to select the items and then click OK. Shift-click and Ctrl-click are supported.
Parameter properties
| Type: | SwitchParameter |
| Default value: | None |
| Supports wildcards: | False |
| DontShow: | False |

| Value from pipeline by property name: | True |
| Value from remaining arguments: | 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.

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