Syntax: format [{[FS=<FS>] [REVISION=<X.XX>] | RECOMMENDED}] [LABEL=<"label">] [UNIT=<N>] [QUICK] [COMPRESS] [OVERRIDE] [NOWAIT] [NOERR]
Formats the volume or partition. A volume must be selected for this operation to succeed.
FS=<FS>
Specifies the type of file system. If no file system is given, the
default file system displayed by the FILESYSTEMS command is used.
REVISION = <X.XX>
Specifies the file system revision (if applicable).
RECOMMENDED
If specified, use the recommended file system and revision instead
of the default if a recommendation exists. The recommended file
system (if one exists) is displayed by the FILESYSTEMS command.
LABEL=<"label">
Specifies the volume label.
UNIT=<N>
Overrides the default allocation unit size. Default settings are
strongly recommended for general use. The default allocation unit
size for a particular file system is displayed by the FILESYSTEMS
command.
NTFS compression is not supported for allocation unit sizes above
4096.
QUICK
Performs a quick format.
COMPRESS
NTFS only: Files created on the new volume will be compressed by
default.
OVERRIDE
Forces the volume to dismount first if necessary. All opened handles
to the volume would no longer be valid.
NOWAIT
Forces the command to return immediately while the format process is
still in progress. If NOWAIT is not specified, DiskPart will display
format progress in percentage.
NOERR
For scripting only. When an error is encountered, DiskPart continues
to process commands as if the error did not occur. Without the NOERR
parameter, an error causes DiskPart to exit with an error code.
Examples:
