Detailed Description

The Format-Volume cmdlet formats one or more existing volumes, or a new volume on an existing partition. This cmdlet returns the object representing the volume that was just formatted, with all properties updated to reflect the format operation.

To create a new volume, use this cmdlet in conjunction with the Initialize-Disk and New-Partition cmdlets.

Parameters

-AllocationUnitSize<UInt32>

Specifies the allocation unit size to use when formatting the volume.

-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.

<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_Volume

    You can pipe an MSFT_Volume object to the InputObject parameter.


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

    You can pipe an MSFT_Partition object to the Partition parameter.


Outputs

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

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

    The Format-Volume cmdlet return an object representing the newly formatted volume.


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: Quick format

This example performs a format of the D volume.


PS C:\> Format-Volume -DriveLetter D

Example 2: Full format using FAT32

This example performs a full format of the D volume using the FAT32 file system.


PS C:\> Format-Volume -DriveLetter C -FileSystem FAT32 -FullFormat –Force
