DISKPART> ACTIVE
On disks with master boot record (MBR) disk formatting, marks
the partition with focus as active.
Syntax: ACTIVE
Writes a value to the disk which is read by the basic input/output
system (BIOS) at boot. This value specifies that the partition is
a valid system partition.
A partition must be selected for this operation to succeed.
Caution:
DiskPart verifies only that the partition is capable of containing the
operating system startup files. DiskPart does not check the contents of
the partition. If you mistakenly mark a partition as active and it does
not contain the operating system startup files, your computer might not
start.
Example:
ACTIVE
DISKPART>ADD
Mirrors the simple volume with focus to the specified disk.
Syntax: ADD DISK=<N> [ALIGN=<N>] [WAIT] [NOERR]
DISK=<N> Specifies a disk, other than the one containing the existing
simple volume, to contain the mirror. You can mirror only
simple volumes. The specified disk must have unallocated space
at least as large as the size of the simple volume you want to
mirror.
ALIGN=<N> Typically used with hardware RAID Logical Unit Number (LUN)
arrays to improve performance. Aligns all volume extents to
the closest alignment boundary. The extent offsets will be
a multiple of <N>.
WAIT Waits for the volume to finish synchronizing with the added
disk before returning. Without the WAIT parameter, DiskPart
returns after the mirrored volume is created and does not wait
for the synchronization to complete.
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.
A volume must be selected for this operation to succeed.
Fault-tolerant volumes such as RAID-5 and mirrored volumes are not
supported in any edition of Windows Vista.
Example:
ADD DISK=2
DISKPART> ASSIGN
Assigns a drive letter or mounted folder pathname to the volume with focus.
Syntax: ASSIGN [LETTER=<D> | MOUNT=<PATH>] [NOERR]
LETTER=<D> The drive letter to assign to the volume.
MOUNT=<PATH>
The mounted folder pathname to assign to the volume.
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.
If no drive letter or mounted folder is specified, the next available drive
letter is assigned. If the drive letter or mounted folder is already in use,
an error is generated.
By using the ASSIGN command, you can change the drive letter associated
with a removable drive.
You cannot assign drive letters to boot volumes or
volumes that contain the paging file. In addition, you cannot assign
a drive letter to an Original Equipment Manufacturer (OEM) partition
unless booted to Windows PE, or any GUID Partition Table (GPT) partition
other than a basic data partition, an ESP partition or a recovery
partition.
A volume must be selected for this operation to succeed.
Example:
ASSIGN LETTER=D
DISKPART> ATTRIBUTES
Microsoft DiskPart version 6.3.9600
VOLUME - Manipulate volume attributes.
DISK - Manipulate disk attributes.
DISKPART> ATTACH
Microsoft DiskPart version 6.3.9600
VDISK - Attaches a virtual disk file.
DISKPART> AUTOMOUNT
Enables or disables the automount feature.
Syntax: AUTOMOUNT [ENABLE] [DISABLE] [SCRUB] [NOERR]
ENABLE Enables Windows to automatically assign drive letters
to volumes that are added to the system.
DISABLE Prevents Windows from automatically assigning drive letters
to volumes that are added to the system.
SCRUB Removes mounted folder pathnames, drive letters, mounted
folder directories, and registry settings, for volumes that
are no longer in the system. This prevents volumes that were
previously in the system from being automatically assigned
their former drive letters and mounted folder pathnames when
they are reintroduced to the system.
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.
When the AutoMount feature is enabled (the default on some versions
of Windows Server), Windows automatically brings the volume online,
and, assigns a drive letter and a volume GUID pathname to the volume,
when the volume is added to the system. In storage area network (SAN)
configurations, disabling AutoMount prevents Windows from automatically
onlining the volume and assigning drive letters or volume GUID pathnames
to any new volumes that are visible to the system.
Note that the AutoMount feature could only be applied to basic disk
volumes on Windows versions released prior to Windows Vista. Starting
with Windows Vista, the AutoMount feature can be applied to both basic
and dynamic disk volumes.
Example:
AUTOMOUNT
AUTOMOUNT ENABLE
AUTOMOUNT DISABLE
DISKPART> BREAK
Breaks the mirrored volume with focus into two simple volumes.
Syntax: BREAK DISK=<N> [NOKEEP] [NOERR]
DISK=<N> Specifies a disk that contains one copy of the mirror
volume. When the command has completed, this disk is
given focus, and the new volume created on this disk
using the mirror volume extents does not retain any
drive letters, volume GUID pathnames or mounted folder
paths that had been associated with the mirror volume.
If the mirror volume on the specified disk is used as a
system or boot partition, the command fails.
NOKEEP Specifies that only one copy of the mirror volume is
retained; the mirror volume extents on disk <N> are converted
to free space. Neither the remaining copy of the mirror
volume, nor the free space on disk <N> receives the focus.
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.
Applies to dynamic disks only. Breaks the mirrored volume with focus into
two simple volumes. One simple volume retains the drive letter, volume
GUID pathnames or mounted folder paths that had been associated with
the mirror volume. The other simple volume receives the focus so you
can assign it a new drive letter (it will automatically be assigned a
volume GUID pathname).
By default, the contents of both copies of the mirror are retained. Each
copy becomes a simple volume. By using the NOKEEP parameter, you retain
only one copy of the mirror volume as a simple volume, and the other copy
is converted to free space. Neither volume receives the focus.
A mirror volume must be selected for this operation to succeed.
Example:
BREAK DISK=2
DISKPART> CLEAN
Removes any and all partition or volume formatting from the disk with
focus.
Syntax: CLEAN [ALL]
ALL Specifies that each and every byte\sector on the disk is set to
zero, which completely deletes all data contained on the disk.
On master boot record (MBR) disks, only the MBR partitioning information
and hidden sector information are overwritten. On GUID partition table
(GPT) disks, the GPT partitioning information, including the Protective
MBR, is overwritten. If the ALL parameter is not used, the first 1MB
and the last 1MB of the disk are zeroed. This erases any disk formatting
that had been previously applied to the disk. The disk's state after
cleaning the disk is 'UNINITIALIZED'.
Example:
CLEAN
DISKPART> COMPACT

DISKPART> EXIT
Exits the DiskPart command interpreter.
Syntax: EXIT
Example:
EXIT
DISKPART>EXTEND
Extends the volume or partition with focus, and its file system, into free
(unallocated) space on a disk.
Syntax: EXTEND [SIZE=<N>] [DISK=<N>] [NOERR]
EXTEND FILESYSTEM [NOERR]
SIZE=<N> Specifies the amount of space in megabytes (MB) to add to the
current volume or partition. If no size is given, all of the
contiguous free space that is available on the disk is used.
DISK=<N> Specifies the disk on which the volume or partition is
extended. If no disk is specified, the volume or partition is
extended on the current disk.
FILESYSTEM Extends the file system of the volume with focus to cover
the entire volume. For use only on volumes where the file
system was not extended with the volume.
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.
On basic disks, the free space must be on the same disk as the volume or
partition with focus. The free space must also immediately follow the
volume or partition with focus (start at the next sector offset).
On dynamic disks with simple or spanned volumes, a volume can be extended
to any free space on any dynamic disk. Using this command, you can convert
a simple dynamic volume into a spanned dynamic volume. Mirrored, RAID-5 and
striped volumes cannot be extended.
If the partition was previously formatted with the NTFS file system, the
file system is automatically extended to fill the larger partition. No data
loss occurs. If the partition was previously formatted with a different
file system than NTFS, the command fails with no change to the partition.
If the partition was not previously formatted with a file system, the
partition will still be extended.
A volume or partition must be selected for this operation to succeed.
Example:
EXTEND SIZE=500 DISK=3
EXTEND FILESYSTEM
DISKPART>EXPAND
Microsoft DiskPart version 6.3.9600
VDISK - Expands the maximum size available on a virtual disk.
DISKPART> FILESYSTEMS
Displays information about the current file system for the selected
volume, and the supported file systems for formatting the volume.
Syntax: FILESYSTEMS
A volume must be selected for this operation to succeed.
Example:
FILESYSTEMS
DISKPART> FORMAT
Formats the specified volume for use with Windows.
Syntax: FORMAT [[FS=<FS>] [REVISION=<X.XX>] | RECOMMENDED] [LABEL=<"label">]
[UNIT=<N>] [QUICK] [COMPRESS] [OVERRIDE] [DUPLICATE] [NOWAIT]
[NOERR]
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 file system to dismount first if necessary. All
opened handles to the volume would no longer be valid.
DUPLICATE UDF Only: This flag applies to UDF format, version 2.5 or
higher.
This flag instructs the format operation to duplicate the file
system meta-data to a second set of sectors on the disk. The
duplicate meta-data is used by applications, for example repair
or recovery applications. If the primary meta-data sectors are
found to be corrupted, the file system meta-data will be read
from the duplicate sectors.
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.
A volume must be selected for this operation to succeed.
Examples:
FORMAT FS=NTFS LABEL="New Volume" QUICK COMPRESS
FORMAT RECOMMENDED OVERRIDE
DISKPART> GPT
On basic GUID partition table (GPT) disks, assigns the GPT attribute(s) to
the partition with focus.
Syntax: GPT ATTRIBUTES=<N>
ATTRIBUTES=<N>
The hexadecimal value indicating the attributes to apply to the
partition with focus. The GPT attribute field is a 64-bit field
that contains two subfields. The higher field is interpreted
only in the context of a particular partition type GUID, while
the lower field is common to all partition types.
