<CommonParameters>

This cmdlet supports the common parameters: -Verbose, -Debug, -ErrorAction, -ErrorVariable, -OutBuffer, and -OutVariable. For more information, see    about_CommonParameters (http://go.microsoft.com/fwlink/p/?LinkID=113216).

Inputs

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

Outputs

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

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: Create a new partition on disk 1

This example creates a new partition on disk 1, using the maximum available space, and automatically assigning a drive letter.


PS C:\> New-Partition -DiskNumber 1 -UseMaximumSize -AssignDriveLetter

Example 2: Get all RAW disks, initialize the disks, partition, and format them

This example uses five cmdlets and the pipeline to get all disks, filter them for only RAW, unpartitioned disks, initialize the disks, partition the disks, and then format them.


 

This line gets all disk objects and then pipes the objects to the next command.


PS C:\> Get-Disk |

 

This line selects only objects where the PartitionStyle property value equals "RAW", and then pipes the objects to the next command.


PS C:\> Where-Object PartitionStyle –Eq "RAW" |

 

This line initializes all Disk objects in the pipeline and then pipes the objects to the next cmdlet.


PS C:\> Initialize-Disk -PassThru |

 

This line creates a maximum sized partition on each initialized Disk object, assigns a drive letter to the partitions, and then pipes the objects to the next cmdlet.


PS C:\> New-Partition -AssignDriveLetter -UseMaximumSize |

 

This line formats all newly partitioned disks.


PS C:\> Format-Volume
