ZPODD 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.


Step 1. Run Command Prompt as an  Administrator. Directly type cmd in 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
 
Step 2.Reboot the system 
 
Step 3.Verify if the problem has been resolved.
