Description
The New-Partition cmdlet creates a partition on a specified Disk object. Note: This cmdlet does not support creating dynamic volumes.
Examples
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.
Required Parameters
Specifies the ID of the disk on which to create the partition.

Type: | UInt32[] |
Position: | 0 |
Default value: | None |
Accept pipeline input: | True (ByPropertyName) |
Accept wildcard characters: | False |
Specifies the path of the disk on which to create the partition.
Type: | String[] |
Position: | Named |
Default value: | None |
Accept pipeline input: | True (ByPropertyName) |
Accept wildcard characters: | False |
Specifies the input object that is used in a pipeline command.
Type: | CimInstance[] |
Position: | Named |
Default value: | None |
Accept pipeline input: | True (ByValue) |
Accept wildcard characters: | False |
Optional Parameters
Specifies the alignment boundary in bytes.
Type: | UInt32 |
Position: | Named |
Default value: | None |
Accept pipeline input: | False |
Accept wildcard characters: | False |
Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete.
Type: | SwitchParameter |
Position: | Named |
Default value: | None |
Accept pipeline input: | False |
Accept wildcard characters: | False |
Assigns a drive letter to the new partition.
Type: | SwitchParameter |
Position: | Named |
Default value: | None |
Accept pipeline input: | False |
Accept wildcard characters: | False |
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.
Type: | CimSession[] |
Aliases: | Session |
Position: | Named |
Default value: | None |
Accept pipeline input: | False |
Accept wildcard characters: | False |
Specifies the specific drive letter to assign to the new partition.
Type: | Char |
Aliases: | NewDriveLetter |
Position: | Named |
Default value: | None |
Accept pipeline input: | False |
Accept wildcard characters: | False |
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)
Type: | String |
Position: | Named |
Default value: | None |
Accept pipeline input: | False |
Accept wildcard characters: | False |
Specifies that the object is marked active.
Type: | SwitchParameter |
Position: | Named |
Default value: | None |
Accept pipeline input: | False |
Accept wildcard characters: | False |
Creates a hidden partition.
Type: | SwitchParameter |
Position: | Named |
Default value: | None |
Accept pipeline input: | False |
Accept wildcard characters: | False |
Specifies the type of MBR partition to create. Valid types are: Extended, FAT12, FAT16, FAT32, Huge, and IFS.
Type: | MbrType |
Parameter Sets: | FAT12, FAT16, Extended, Huge, IFS, FAT32 |
Position: | Named |
Default value: | None |
Accept pipeline input: | False |
Accept wildcard characters: | False |
Specifies the starting offset, in bytes.
Type: | UInt64 |
Position: | Named |
Default value: | None |
Accept pipeline input: | False |
Accept wildcard characters: | False |
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 .
Type: | UInt64 |
Position: | Named |
Default value: | None |
Accept pipeline input: | False |
Accept wildcard characters: | False |
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.
Type: | Int32 |
Position: | Named |
Default value: | None |
Accept pipeline input: | False |
Accept wildcard characters: | False |
Creates the largest possible partition on the specified disk.
Type: | SwitchParameter |
Position: | Named |
Default value: | None |
Accept pipeline input: | False |
Accept wildcard characters: | False |
Inputs
Microsoft.Management.Infrastructure.CimInstance#ROOT/Microsoft/Windows/Storage/MSFT_Disk
You can pipe a Disk object to the InputObject parameter.
Outputs
Microsoft.Management.Infrastructure.CimInstance#ROOT/Microsoft/Windows/Storage/MSFT_Partition
This cmdlet outputs an object that represents the newly created partition.
