DESCRIPTION

The New-Partition cmdlet creates a partition on a specified Disk object. Note: This cmdlet does not support creating dynamic volumes.





PARAMETERS

-Alignment [<UInt32>]

Specifies the alignment boundary in bytes.



Required? false

Position? named

Default value none

Accept pipeline input? false

Accept wildcard characters? false



-AssignDriveLetter [<SwitchParameter>]

Assigns a drive letter to the new partition.



Required? false

Position? named

Default value none

Accept pipeline input? false

Accept wildcard characters? false



-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.



Required? false

Position? named

Default value none

Accept pipeline input? false

Accept wildcard characters? false



-DiskId <String[]>

Specifies the ID of the disk on which to create the partition.



Required? true

Position? named

Default value none

Accept pipeline input? True (ByPropertyName)

Accept wildcard characters? false



-DiskNumber <UInt32[]>

Specifies an array of disk numbers.



Required? true

Position? 1

Default value none

Accept pipeline input? True (ByPropertyName)

Accept wildcard characters? false



-DiskPath <String[]>

Specifies the path of the disk on which to create the partition.



Required? true

Position? named

Default value none

Accept pipeline input? True (ByPropertyName)

Accept wildcard characters? false



-DriveLetter [<Char>]

Specifies the specific drive letter to assign to the new partition.



Required? false

Position? named

Default value none

Accept pipeline input? false

Accept wildcard characters? false



-GptType [<String>]

Specifies the type of GPT partition to create (by GUID). By default, the New-Partition cmdlet creates a basic GPT data partition.



The GUIDs of valid types are:



-- System Partition (c12a7328-f81f-11d2-ba4b-00a0c93ec93b)



-- Microsoft Reserved (e3c9e316-0b5c-4db8-817d-f92df00215ae)



-- Basic data (ebd0a0a2-b9e5-4433-87c0-68b6b72699c7)



-- Microsoft Recovery (de94bba4-06d1-4d40-a16a-bfd50179d6ac)



Required? false

Position? named

Default value none

Accept pipeline input? false

Accept wildcard characters? false



-IsActive [<SwitchParameter>]

Specifies that the object is marked active.



Required? false

Position? named

Default value none

Accept pipeline input? false

Accept wildcard characters? false



-IsHidden [<SwitchParameter>]

Creates a hidden partition.



Required? false

Position? named

Default value none

Accept pipeline input? false

Accept wildcard characters? false



-MbrType [<MbrType>]

Specifies the type of MBR partition to create. Valid types are: Extended, FAT12, FAT16, FAT32, Huge, and IFS.



Required? false

Position? named

Default value none

Accept pipeline input? false

Accept wildcard characters? false



-Offset [<UInt64>]

Specifies the starting offset, in bytes.



Required? false

Position? named

Default value none

Accept pipeline input? false

Accept wildcard characters? false



-Size [<UInt64>]

Specifies the size of the partition to create. If not specified, then the units will default to Bytes. The acceptable value for this parameter is a

positive number followed by the one of the following unit values: Bytes, KB, MB, GB, or TB.



Required? false

Position? named

Default value none

Accept pipeline input? false

Accept wildcard characters? false



-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.



Required? false

Position? named

Default value none

Accept pipeline input? false

Accept wildcard characters? false



-UseMaximumSize [<SwitchParameter>]

Creates the largest possible partition on the specified disk.



Required? false

Position? named

Default value none

Accept pipeline input? false

Accept wildcard characters? false



<CommonParameters>

This cmdlet supports the common parameters: Verbose, Debug,

ErrorAction, ErrorVariable, WarningAction, WarningVariable,

OutBuffer, PipelineVariable, and OutVariable. For more information, see

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.
