DiskPart Utility (Compact 2013)

10/16/2014

DiskPart is a command prompt utility that you can use to partition a disk.


DiskPart

The DiskPart utility writes the metadata on the disk that is required to boot a Windows Embedded Compact image from that disk. You can use DiskPart to run scripts, and use it on larger hard disks to be able to boot from FAT32 and extended FAT (ExFAT) partitions.

  • DiskPart does not support extended partitions currently
  • DiskPart will not format the partition volume with a file system

The following list shows the commands that the DiskPart command prompt utility supports:

Command

Action

ACTIVE

Sets the selected partition to active. The boot sector is read from this partition.

INACTIVE

Clears the active flag on the partition.

CLEAN

Deletes the whole partition on the selected disk.

CREATE

Creates a primary partition on the selected disk.

DELETE

Deletes the selected partition from the selected disk.

LIST

Displays all the disks, or the partitions on a selected disk.

SELECT

Selects a disk or partition.

DUMPMBR

Displays the partition table of the master boot record (MBR).

DUMPSTORE

Displays the STOREINFO for the selected disk.

DUMPPART

Displays the PARTINFO for the selected partition.

ZERO

Writes all zeros to a given sector

DUMPSECTOR

Displays the contents of a sector on the disk.

MBRCODE

Writes a file to the MBR code section

BOOTSEC

Writes a file to the given sector on the disk.

FIXPARTOFFSET

Updates the Bios Parameter Block (BPB) with the correct offset of the partition.

HELP

Displays a list of supported commands.

To run DiskPart with a script file, add the commands you want to use in a text file. Then, provide this text file to DiskPart by using the -s parameter command at the DOS command prompt. The following example shows you how to provide a text file to DiskPart by using the -s parameter command:

DiskPart -s <myscript.s>

Make sure that you enter Exit as the last command in the script. This enables DiskPart to close after it runs all the commands in the script.
