3/26/2014

The following table shows the Block driver IOCTLs with a description of the purpose of each.

Programming element	Description
IOCTL_CDROM_DISC_INFO	This IOCTL retrieves disc information to fill the CDROM_DISCINFO structure.
IOCTL_CDROM_EJECT_MEDIA	The IOCTL ejects the CD-ROM.
IOCTL_CDROM_GET_SENSE_DATA	This IOCTL specifies retrieval of a CD-ROM sense information contained in a CD_SENSE_DATA structure.
IOCTL_CDROM_ISSUE_INQUIRY	This IOCTL retrieves information used in the INQUIRY_DATA structure.
IOCTL_CDROM_PAUSE_AUDIO	This IOCTL suspends audio play.
IOCTL_CDROM_PLAY_AUDIO_MSF	This IOCTL plays audio from the specified range of the medium.
IOCTL_CDROM_READ_SG	This IOCTL reads scatter buffers from the CD-ROM and the information is stored in the CDROM_READ structure.
IOCTL_CDROM_READ_TOC	This IOCTL returns the table of contents of the medium.
IOCTL_CDROM_RESUME_AUDIO	This IOCTL resumes a suspended audio operation.
IOCTL_CDROM_SEEK_AUDIO_MSF	This IOCTL moves the heads to the specified minutes, seconds, and frames on the medium.
IOCTL_CDROM_STOP_AUDIO	This IOCTL stops audio play.
IOCTL_CDROM_TEST_UNIT_READY	This IOCTL retrieves disc ready information and fills the CDROM_TESTUNITREADY structure.
IOCTL_DISK_DEVICE_INFO	This IOCTL returns storage information to block device drivers.
IOCTL_DISK_FLUSH_CACHE	This IOCTL is issued by the FAT file system when a storage device has an associated hardware cache, and the device driver reports that the cache needs to be flushed for transfers.
IOCTL_DISK_FORMAT_MEDIA	This IOCTL is issued by the FAT file system when a device driver reports that the disk needs a low-level format.
IOCTL_DISK_GET_SECTOR_ADDR	This IOCTL receives an array of logical sectors and returns an array of addresses. Each array of addresses corresponds to the statically mapped virtual address for a particular logical sector.
IOCTL_DISK_GET_STORAGEID	This IOCTL returns the current STORAGE_IDENTIFICATION structure for a particular storage device.
IOCTL_DISK_GETINFO	This IOCTL notifies block device drivers to return disk information.
IOCTL_DISK_GETNAME	This IOCTL services the request from the FAT file system for the name of the folder that determines how users access the block device.
IOCTL_DISK_READ	This IOCTL services FAT file system requests to read data from the block device.
IOCTL_DISK_SECURE_WIPE	This IOCTL specifies a secure removal of all specified sectors.
IOCTL_DISK_SET_SECURE_WIPE_FLAG	This IOCTL sets a flag indicating a secure wipe is to be performed.
IOCTL_DISK_SETINFO	This IOCTL services FAT file system requests to set disk information.
IOCTL_DISK_WRITE	This IOCTL services FAT file system requests to write data to the block device.
IOCTL_DVD_GET_REGION	This IOCTL returns DVD disk and drive regions.
