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_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_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. |
