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.
Examples Example 1: Quick formatPS C:\>Format-Volume -DriveLetter D
This example performs a format of the D volume.
Example 2: Full format using FAT32PS C:\>Format-Volume -DriveLetter D -FileSystem FAT32 -Full -Force
This example performs a full format of the D volume using the FAT32 file system.
Example 3: Format all D drives across a clusterPS C:\> Get-Volume -DriveLetter D
DriveLetter FileSystemLabel FileSystem DriveType HealthStatus OperationalStatus SizeRemaining Size
----------- --------------- ---------- --------- ------------ ----------------- ------------- ----
D Server1 NTFS Fixed Healthy OK 126.76 GB 126.87 GB
D Server2 NTFS Fixed Healthy OK 126.76 GB 126.87 GB
PS C:\> Format-Volume -DriveLetter D
DriveLetter FileSystemLabel FileSystem DriveType HealthStatus OperationalStatus SizeRemaining Size
----------- --------------- ---------- --------- ------------ ----------------- ------------- ----
D NTFS Fixed Healthy OK 126.76 GB 126.87 GB
D NTFS Fixed Healthy OK 126.76 GB 126.87 GB
Be careful, if using this cmdlet on a Windows Cluster, it would format all drives returned by the Get-Volume cmdlet.
Example 4: Full format using NTFS and allocation size 8192PS C:\> Format-Volume -DriveLetter D -FileSystem NTFS -AllocationUnitSize 8192
This example performs a full format of the D volume using the NTFS file system and allocation size 8192.
Parameters -AllocationUnitSizeSpecifies the allocation unit size to use when formatting the volume.
Type: UInt32 Aliases: ClusterSize Position: Named Default value: None Required: False Accept pipeline input: False Accept wildcard characters: False -AsJobRuns 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 Required: False Accept pipeline input: False Accept wildcard characters: False -CimSessionRuns 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 Required: False Accept pipeline input: False Accept wildcard characters: False -CompressEnables compression on all files and folders created on the specified NTFS volume.
Type: SwitchParameter Position: Named Default value: None Required: False Accept pipeline input: False Accept wildcard characters: False -ConfirmPrompts you for confirmation before running the cmdlet.
Type: SwitchParameter Aliases: cf Position: Named Default value: False Required: False Accept pipeline input: False Accept wildcard characters: False -DevDriveFormats the volume as a dev drive. A dev drive is optimized for performance of developer scenarios and gives administators control over what minifilters are attached to the volume.
Type: SwitchParameter Position: Named Default value: False Required: False Accept pipeline input: False Accept wildcard characters: False -DisableHeatGatheringIndicates that the cmdlet does not gather file activity on the specified tiered volume. You can override file placement based on the desired storage tier. This parameter is only valid for tiered volumes.
Type: SwitchParameter Position: Named Default value: None Required: False Accept pipeline input: False Accept wildcard characters: False -DriveLetterSpecifies the drive letter of the volume to format.
Type: Char[] Position: 0 Default value: None Required: True Accept pipeline input: True Accept wildcard characters: False -FileSystemSpecifies the file system with which to format the volume. The acceptable values for this parameter are:NTFS, ReFS, exFAT, FAT32, and FAT.
Type: String Accepted values: FAT, FAT32, exFAT, NTFS, ReFS Position: Named Default value: None Required: False Accept pipeline input: False Accept wildcard characters: False -FileSystemLabelSpecifies the label to use for the volume.
Type: String[] Position: Named Default value: None Required: True Accept pipeline input: True Accept wildcard characters: False -ForceSpecifies the override switch.
Type: SwitchParameter Position: Named Default value: None Required: False Accept pipeline input: False Accept wildcard characters: False -FullPerforms a full format. A full format writes to every sector of the disk, takes much longer to perform than the default (quick) format, and is not recommended on storage that is thinly provisioned.
Type: SwitchParameter Position: Named Default value: None Required: False Accept pipeline input: False Accept wildcard characters: False -InputObjectSpecifies the input object that is used in a pipeline command.
Type: CimInstance[] Position: Named Default value: None Required: True Accept pipeline input: True Accept wildcard characters: False -IsDAXFormats a volume as a DirectAccess (DAX) volume.
DAX provides applications with direct access and byte-addressability options via memory mapping on storage class memory (SCM) devices, such as NVDIMM-N.
If you do not specify the IsDAX parameter, the cmdlet defaults to a regular, non-DAX volume.
Type: Boolean Position: Named Default value: None Required: False Accept pipeline input: False Accept wildcard characters: False -NewFileSystemLabelSpecifies a new label to use for the volume.
Type: String Position: Named Default value: None Required: False Accept pipeline input: False Accept wildcard characters: False -ObjectIdSpecifies the ID of the volume to format.
Type: String[] Aliases: Id Position: Named Default value: None Required: True Accept pipeline input: True Accept wildcard characters: False -PartitionSpecifies the partition object on which to create the new volume. Enter a Partition CIM object, which is exposed by the Get-Partition and New-Partition cmdlets.
Type: CimInstance Position: Named Default value: None Required: False Accept pipeline input: True Accept wildcard characters: False -PathSpecifies the path of the volume to format.
Type: String[] Position: Named Default value: None Required: True Accept pipeline input: True Accept wildcard characters: False -SetIntegrityStreamsEnables integrity streams on the volume to be formatted.
Type: Boolean Position: Named Default value: None Required: False Accept pipeline input: False Accept wildcard characters: False -ShortFileNameSupportSpecifies that support for short file names should be enabled on this volume.
Type: Boolean Position: Named Default value: None Required: False Accept pipeline input: False Accept wildcard characters: False -ThrottleLimitSpecifies 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.
Specifies that large File Record Segment (FRS) should be used.
Type: SwitchParameter Position: Named Default value: None Required: False Accept pipeline input: False Accept wildcard characters: False -WhatIfShows what would happen if the cmdlet runs. The cmdlet is not run.
NOTE: The WhatIf switch does not work with this cmdlet.
Type: SwitchParameter Aliases: wi Position: Named Default value: False Required: False Accept pipeline input: False Accept wildcard characters: False InputsYou can use the pipeline operator to pass an MSFT_Volume object to the InputObject parameter.
You can use the pipeline operator to pass an MSFT_Partition object to the Partition parameter.
OutputsThis cmdlet returns an object that represents the newly formatted volume.
