Windows 7 Cd-rom Driver Download
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. For more info, see CD-ROM I/O control codes

Class drivers for CD-ROM devices handle additional public I/O control codes, along with those described in this section. For more information about requirements for storage class drivers, see General Storage I/O Control Codes.
Hi, Most, not all, CD and DVD drives use the default Windows drivers. Try the methods here and if needed check with the System maker's Support and Forums (if any) as well as the actual drive/device maker's support. Stage 1 : Please do all the below even if you have done some before as it is often the total process which solves the issue. Try this - Control Panel - Device Manager - CD/DVD - double click the device - Driver's Tab - click Update Drivers (this will likely do nothing) - then RIGHT CLICK the drive - UNINSTALL - REBOOT this will refresh the default driver stack. Even if drive is not shown continue below.
Then work your way through these - remember the drive could be bad, could have a loose cable or slight corrosion on the contacts (usually for a laptop) and other issues.

Remove ALL power, then check cables in both ends. Remove and replace, do not just snug. For laptops you can often clean the power and data contacts with a pencil eraser. Some DVD drives do not use the Windows default drivers so check with the System maker and device maker to see if there is firmware or drivers for you drive if needed. Stage 2 : You could have drive issues as the CD/DVD is actually 4 drives in 1 case ( CD & DVD burn and CD and DVD read). So it is not unusual for 1 or 2 parts to not function while the others do so properly. Did you complete the troubleshooter for the drive that still does not work? There are some registry entries that the troubleshooter does not fix and those 'might' be the cause. Check with your System Maker and Device maker for both possible firmware updates and the correct Registry entries for your drive. These are the keys I think are the ones in question - for the CD/DVD drive sub-keys of course as there will other sub-keys in these keys. Be sure to ask for specific keys involved as well as the settings.
