Programming element Description
IOCTL_CDROM_DISC_INFO This IOCTL retrieves disc information to fill the CDROM_DISCINFO structure.
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_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.
