about_CommonParameters (https:/go.microsoft.com/fwlink/?LinkID=113216).
INPUTS
Microsoft.Management.Infrastructure.CimInstance#ROOT/Microsoft/Windows/Storage/MSFT_Disk
http://msdn.microsoft.com/library/windo ... 30493.aspx
You can pipe a Disk object to the InputObject parameter.
OUTPUTS
Microsoft.Management.Infrastructure.CimInstance#ROOT/Microsoft/Windows/Storage/MSFT_Partition
http://msdn.microsoft.com/library/windo ... 30524.aspx
This cmdlet outputs an object that represents the newly created partition.
Example 1: Create a new partition on disk 1
PS C:\\> New-Partition -DiskNumber 1 -UseMaximumSize -AssignDriveLetter
This example creates a new partition on disk 1, using the maximum available space, and automatically assigning a drive letter.
Example 2: Get all RAW disks, initialize the disks, partition, and 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
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.
