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 format

PS C:\>Format-Volume -DriveLetter D

This example performs a format of the D volume.

Example 2: Full format using FAT32

PS C:\>Format-Volume -DriveLetter C -FileSystem FAT32 -FullFormat -Force

This example performs a full format of the D volume using the FAT32 file system.

PARAMETERS

-AllocationUnitSize

Specifies the allocation unit size to use when formatting the volume.

Type: UInt32
Parameter Sets: (All)
Aliases: ClusterSize

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-AsJob

Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete.

Type: SwitchParameter
Parameter Sets: (All)
Aliases: 

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-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.

Type: CimSession[]
Parameter Sets: (All)
Aliases: Session

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-Compress

Enables compression on all files and folders created on the specified NTFS volume.

Type: SwitchParameter
Parameter Sets: (All)
Aliases: 

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-Confirm

Prompts you for confirmation before running the cmdlet.

Type: SwitchParameter
Parameter Sets: (All)
Aliases: cf

Required: False
Position: Named
Default value: False
Accept pipeline input: False
Accept wildcard characters: False

-DisableHeatGathering

Indicates 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
Parameter Sets: (All)
Aliases: 

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-DriveLetter

Specifies the drive letter of the volume to format.

Type: Char[]
Parameter Sets: ByDriveLetter
Aliases: 

Required: True
Position: 0
Default value: None
Accept pipeline input: True (ByPropertyName)
Accept wildcard characters: False

-FileSystem

Specifies the file system with which to format the volume. The acceptable values for this parameter are:NTFS, ReFS, exFAT, FAT32, and FAT.

Type: String
Parameter Sets: (All)
Aliases: 
Accepted values: FAT, FAT32, exFAT, NTFS, ReFS

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-FileSystemLabel

Specifies the label to use for the volume.

Type: String[]
Parameter Sets: ByLabel
Aliases: 

Required: True
Position: Named
Default value: None
Accept pipeline input: True (ByPropertyName)
Accept wildcard characters: False

-Force

Specifies the override switch.

Type: SwitchParameter
Parameter Sets: (All)
Aliases: 

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-Full

Performs 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
Parameter Sets: (All)
Aliases: 

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-InputObject

Specifies the input object that is used in a pipeline command.

Type: CimInstance[]
Parameter Sets: InputObject (cdxml)
Aliases: 

Required: True
Position: Named
Default value: None
Accept pipeline input: True (ByValue)
Accept wildcard characters: False

-IsDAX

Formats 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
Parameter Sets: (All)
Aliases: 

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-NewFileSystemLabel

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

Aliases: Id

Required: True
Position: Named
Default value: None
Accept pipeline input: True (ByPropertyName)

Type: CimInstance
Parameter Sets: ByPartition
Aliases: 

Required: False
Position: Named
Default value: None
Accept pipeline input: True (ByValue)
Accept wildcard characters: False

-Path

Specifies the path of the volume to format.

Type: String[]

Aliases: 

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-ThrottleLimit

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
Parameter Sets: (All)
Aliases: 

Required: False
