Creates an extended partition on the disk with focus.
For examples of how this command can be used, see Examples.
Syntax
create partition extended [size=<n>] [offset=<n>] [align=<n>] [noerr]
Parameters
Parameter | Description |
---|---|
size=<n> |
The size of the partition in megabytes (MB). If no size is given, the partition continues until there is no more free space in the region. |
offset=<n> |
Applies to master boot record (MBR) disks only. The offset in kilobytes (KB), at which the partition is created. If no offset is given, the partition will start at the beginning of the largest disk extent that is free. |
align=<n> |
Typically used with hardware RAID Logical Unit Number (LUN) arrays to improve performance. Aligns all volume or partition extents to the closest alignment boundary. n is the number of kilobytes (KB) from the beginning of the disk to the closest alignment boundary. |
noerr |
For scripting only. When an error is encountered, DiskPart continues to process commands as if the error did not occur. Without this parameter, an error causes DiskPart to exit with an error code. |
Remarks
- After the partition has been created, the focus automatically
shifts to the new partition.
- Only one extended partition can be created per disk.
- This command fails if you attempt to create an extended
partition within another extended partition.
- You must create an extended partition before you can create
logical drives.
- A basic MBR disk must be selected for this operation to
succeed. Use the select disk command to select a disk and
shift the focus to it.
Examples
To create an extended partition of 1000 megabytes in size, type:
create partition extended size=1000
