Disk Management Structures

The following list identifies the structures that are used in disk management.

In this section

StructureDescription

CREATE_DISK

Contains information that the IOCTL_DISK_CREATE_DISK control code uses to initialize GUID partition table (GPT), master boot record (MBR), or raw disks.

CREATE_DISK_GPT

Contains information used by the IOCTL_DISK_CREATE_DISK control code to initialize GUID partition table (GPT) disks.

CREATE_DISK_MBR

Contains information that the IOCTL_DISK_CREATE_DISK control code uses to initialize master boot record (MBR) disks.

DEVICE_COPY_OFFLOAD_DESCRIPTOR

DEVICE_SEEK_PENALTY_DESCRIPTOR

Used in conjunction with the IOCTL_STORAGE_QUERY_PROPERTY request to retrieve the seek penalty descriptor data for a device.

DEVICE_TRIM_DESCRIPTOR

Used in conjunction with the IOCTL_STORAGE_QUERY_PROPERTY request to retrieve the trim descriptor data for a device.

DEVICE_WRITE_AGGREGATION_DESCRIPTOR

Used in conjunction with the IOCTL_STORAGE_QUERY_PROPERTY control code to retrieve the write aggregation data for a device.

DEVICE_POWER_DESCRIPTOR

The DEVICE_POWER_DESCRIPTOR structure describes the power capabilities of a storage device.

DISK_CACHE_INFORMATION

Provides information about the disk cache.

DISK_GEOMETRY

Describes the geometry of disk devices and media.

DISK_GEOMETRY_EX

Describes the extended geometry of disk devices and media.

DISK_GROW_PARTITION

Contains information used to increase the size of a partition.

DISK_INT13_INFO

Contains standard Int13 drive geometry parameters.

DISK_PARTITION_INFO

STORAGE_DEVICE_RESILIENCY_DESCRIPTOR

Contains the resiliency capabilities for a storage device.

STORAGE_MINIPORT_DESCRIPTOR

Used in conjunction with the IOCTL_STORAGE_QUERY_PROPERTY request to retrieve the storage adapter miniport driver descriptor data for a device.

STORAGE_PROPERTY_QUERY

Indicates the properties of a storage device or adapter to retrieve as the input buffer passed to the IOCTL_STORAGE_QUERY_PROPERTY control code.

STORAGE_WRITE_CACHE_PROPERTY

Used with the IOCTL_STORAGE_QUERY_PROPERTY control code to retrieve information about a device's write cache property.
