I have a 5 day old HP computer. E9220Y. I hooked up my 6mo old LG USB DVD Multi drive up to it and it workds fine. The only problem is, when I restart Windows, it hands right after the BIOS screen. It will not start. I worked for a while trying to figure out why. At first I thought a program I installed screwed it all up, but found if I unplugged the USB cable from the drive, hit the power button again on the computer, it would then start up. Not sure why. Just a plug and play drive. No disc in it. Hooked to a USB port on the back of the computer. Any ideas? I really like the drive.
