The CD-ROM exclusive access mechanism (also known as exclusive access mode) enables applications and system components to obtain exclusive access to a CD-ROM device. Applications that require exclusive access to CD-ROM devices include the following examples. Version 2 of the SCSI-3 Multimedia Commands (MMC) specification defines two commands for setting the CD-ROM speed: SET CD SPEED and SET STREAMING. In Windows Vista, applications can instruct the CD-ROM class driver to issue one of these two commands by sending an IOCTLCDROMSETSPEED request to the class driver.

Consequently, the input or output data for these requests is at Irp-AssociatedIrp.SystemBuffer. Class drivers for CD-ROM devices handle additional public I/O control codes, along with those described in this section. When the operating system enumerates a CD-ROM device, it loads a native CD-ROM class driver (Cdrom.sys). This driver exposes an I/O control request (IOCTL) interface. All public I/O control codes for drivers of CD-ROM devices use buffered I/O. Consequently, the input or output data for these requests is at Irp-AssociatedIrp.SystemBuffer.

Before you begin

Driver updates for Windows 10, along with many devices, such as network adapters, monitors, printers, and video cards, are automatically downloaded and installed through Windows Update. You probably already have the most recent drivers, but if you'd like to manually update or reinstall a driver, here's how: Dtrinc driver download for windows 10 32-bit.

Update the device driver

In the search box on the taskbar, enter device manager, then select Device Manager.
Select a category to see names of devices, then right-click (or press and hold) the one you’d like to update.
Select Search automatically for updated driver software.
Select Update Driver.
If Windows doesn't find a new driver, you can try looking for one on the device manufacturer's website and follow their instructions.

Reinstall the device driver

In the search box on the taskbar, enter device manager, then select Device Manager.
Right-click (or press and hold) the name of the device, and select Uninstall.
Restart your PC.
Windows will attempt to reinstall the driver.

IOCTL_CDROM_ENABLE_STREAMING

I/O control code	Description
IOCTL_CDROM_CHECK_VERIFY	This IOCTL is replaced by IOCTL_STORAGE_CHECK_VERIFY. The only difference between the two IOCTLs is the base value.
IOCTL_CDROM_CLOSE_DOOR	This I/O control code has been replaced by IOCTL_STORAGE_LOAD_MEDIA.
IOCTL_CDROM_ENABLE_STREAMING	Enables or disables CDROM streaming mode on a per-handle basis for raw read and write requests. To perform this operation, call the DeviceIoControl function and specify the IOCTL_CDROM_ENABLE_STREAMING I/O control request as the dwIoControlCode parameter.
IOCTL_CDROM_EXCLUSIVE_ACCESS	Instructs the CD-ROM class driver to export the access state of a CD-ROM device, lock a CD-ROM device for exclusive access, and unlock a CD-ROM device for exclusive access.
IOCTL_CDROM_FIND_NEW_DEVICES	This IOCTL is replaced by IOCTL_STORAGE_FIND_NEW_DEVICES. The only difference between the two IOCTLs is the base value.
IOCTL_CDROM_GET_CONFIGURATION	Requests feature and profile information from a CD-ROM device.
IOCTL_CDROM_GET_CONTROL	This IOCTL request is obsolete. Do not use.
IOCTL_CDROM_GET_DRIVE_GEOMETRY	Returns information about the CD-ROM's geometry (media type, number of cylinders, tracks per cylinder, sectors per track, and bytes per sector).
IOCTL_CDROM_GET_DRIVE_GEOMETRY_EX	Returns information about a CD-ROM's geometry (media type, number of cylinders, tracks per cylinder, sectors per track, and bytes per sector).
IOCTL_CDROM_GET_INQUIRY_DATA	Returns the SCSI inquiry data for the CD-ROM device. This IOCTL can be used when a device has been exclusively locked with IOCTL_CDROM_EXCLUSIVE_ACCESS.
IOCTL_CDROM_GET_LAST_SESSION	Queries the device for the first complete session number, the last complete session number, and the last complete session starting address.
IOCTL_CDROM_GET_PERFORMANCE	Retrieves the supported speeds from the device. The IOCTL_CDROM_GET_PERFORMANCE I/O control request is a wrapper over the MMC command, GET PERFORMANCE.
IOCTL_CDROM_GET_VOLUME	Obsolete. Determines the current volume for each of its device's audio ports.
IOCTL_CDROM_LOAD_MEDIA	Draws a protruding CDROM tray back into the drive.
IOCTL_CDROM_PAUSE_AUDIO	Obsolete. Suspends audio play.
IOCTL_CDROM_PLAY_AUDIO_MSF	Obsolete. Plays the specified range of the media.	Reads data from the CD-ROM in raw mode.
IOCTL_CDROM_READ_Q_CHANNEL	Obsolete. Returns the current position, media catalog, or ISRC track data.
IOCTL_CDROM_READ_TOC	Obsolete. Returns the table of contents of the media.
IOCTL_CDROM_READ_TOC_EX	Queries the target device for the table of contents (TOC), the program memory area (PMA), and the absolute time in pregroove (ATIP).
IOCTL_CDROM_RESUME_AUDIO	Obsolete. Resumes a suspended audio operation.
IOCTL_CDROM_SEEK_AUDIO_MSF	Obsolete. Moves the heads to the specified MSF on the media.
IOCTL_CDROM_SEND_OPC_INFORMATION	Used in file systems and other implementations that want to perform the Optimum Power Calibration (OPC) procedure in advance, so that the first streaming write does not have to wait for the procedure to finish.
IOCTL_CDROM_SET_SPEED	Sets the spindle speed of the CD-ROM drive.
IOCTL_CDROM_SET_VOLUME	Obsolete. Resets the volume for its device's audio ports.
IOCTL_CDROM_STOP_AUDIO	Obsolete. Ends audio play.
