Missing dvd

Hi, my Lite-on dvd disappear from my computer. O/S Win 7 Pro 64. When I boot up, the Lite-on was installed . I can see it in my bios and in my computer screen. Then, all of sudden the drive disappear. I can open and close the dvd door but I can’t access it. This also happens when I swapped out for a Samsung dvd writer. I have swapped out sata cables and power connectors. No luck. Any ideas how to fix it. I have also attach the sata cable to a different sata port on my m/b.
Thanks
