I have been through several discussion about an issue with windows 8 out of which the DVD /CD drives no longer get detected. well here is some explanation
to it and a way to make it work if it is not working as expected.
Zero Power Optical Disk Drive
Zero Power Optical Disk Drive (Zero Power ODD or ZPODD) is one of many new Windows 8 features introduced for power efficiency. On a system enabled with ZPODD, when Windows 8 detects
that there is no media in an optical drive, power to the optical drive is cut off. As soon as the user attempts to use the optical drive, power to the optical drive automatically resumes and the user will be able to use the optical drive immediately, unaware
that the power to the device was ever turned off. Everything happens in the background and normal user interaction is not affected. ZPODD applies only to optical drives that use the slimline SATA connector and is typically found on laptops. Some servers and
desktops also use a slimline SATA connector for optical drives.
In order for ZPODD to work, the ZPODD feature must be supported by the optical drive, the motherboard, and the BIOS.
In some cases even after inserting a Disk in the drive, the drive icon still doesn't show up. you may follow the steps below to make that work.
- Run Command Prompt as an Administrator. Directly type cmdin the new Start Screen(a.k.a Windows 8 Metro UI) and press cltr+shift+enter.
Now copy the following , right click command prompt and
select paste and the
Enter.
reg.exe add "HKLM\System\CurrentControlSet\Services\atapi\Controller0" /f /v EnumDevice1 /t REG_DWORD /d 0x00000001
2.Reboot the system
3.Verify if the problem has been resolved.
