Detailed 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.

Parameters

-AsJob

Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete. The cmdlet immediately returns an object that represents the job and then displays the command prompt. You can continue to work in the session while the job completes. To manage the job, use the *-Job cmdlets. To get the job results, use the Receive-Job cmdlet. For more information about Windows PowerShell® background jobs, see about_Jobs.

-CimSession<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.

-ThrottleLimit<Int32>

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.

<CommonParameters>

This cmdlet supports the common parameters: -Verbose, -Debug, -ErrorAction, -ErrorVariable, -OutBuffer, and -OutVariable. For more information, see    about_CommonParameters.

Inputs

The input type is the type of the objects that you can pipe to the cmdlet.

  • Microsoft.Management.Infrastructure.CimInstance#ROOT/Microsoft/Windows/Storage/MSFT_VirtualDisk

    You can pipe an MSFT_VirtualDisk object to the VirtualDisk parameter.


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

    You can pipe an MSFT_Disk object to the InputObject parameter.


Outputs

The output type is the type of the objects that the cmdlet emits.

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

    If you specify the Passthru parameter, this cmdlet returns an object representing the newly initialized disk.


Notes

  • 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.

Examples

Example 1: Initialize a disk using default values

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.


PS C:\> Initialize-Disk -Number 1

Example 2: Initialize a disk using the MBR partition style

This example initializes a disk using the MBR partition style.


PS C:\> Initialize-Disk -Number 1 -PartitionStyle MBR

Example 3: Initialize a virtual disk

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.


PS C:\> Initialize-Disk -VirtualDisk (Get-VirtualDisk -FriendlyName UserData)
