Disk Management Control Codes

The following table identifies the control codes that are used in disk management.

In This Section

Topic	Description
	Initializes the specified disk and disk partition table using the information in the structure.
	Removes the boot signature from the master boot record, so that the disk will be formatted from sector zero to the end of the disk.
	Formats a specified, contiguous set of tracks on a floppy disk. To provide additional parameters, use instead.
	Formats a specified, contiguous set of tracks on a floppy disk.
	Retrieves the disk cache configuration data.
	Retrieves information about the physical disk's geometry: type, number of cylinders, tracks per cylinder, sectors per track, and bytes per sector.
	Retrieves extended information about the physical disk's geometry: type, number of cylinders, tracks per cylinder, sectors per track, and bytes per sector.
	Retrieves information for each entry in the partition tables for a disk.
	Retrieves extended information for each entry in the partition tables for a disk.
	Retrieves the length of the specified disk, volume, or partition.
	Retrieves information about the type, size, and nature of a disk partition.
	Retrieves extended information about the type, size, and nature of a disk partition.
	Enlarges the specified partition.
	Determines whether the specified disk is writable.
	Enables performance counters that provide disk performance information.
	Disables the performance counters that provide disk performance information.
	Directs the disk device to map one or more blocks to its spare-block pool.
	Directs the disk device to map one or more blocks to its spare-block pool.
	Clears all Volume Shadow Copy Service (VSS) hardware-based shadow copy (also called "snapshot") information from the disk. To perform this operation, call the function with the following parameters.
	Sets the disk configuration data.
	Partitions a disk as specified by drive layout and partition information data.
	Partitions a disk according to the specified drive layout and partition information data.
	Sets partition information for the specified disk partition.
	Sets partition information for the specified disk partition, including layout information for AT and EFI (Extensible Firmware Interface) partitions.
	Invalidates the cached partition table and re-enumerates the device.
	Verifies the specified extent on a fixed disk.
	Returns the properties of a storage device or adapter. The request indicates the kind of information to retrieve, such as the inquiry data for a device or the capabilities and limitations of an adapter. can also be used to determine whether the port driver supports a particular property or which fields in the property descriptor can be modified with a subsequent change-property request.
