hey,

The software is irralevant, you can't see the drive in my computer and not in device manager.

The thing is on a cold boot he sometimes does everything ok (he recognize it) and other times not.

I have a asus P4P800-vm motherboard and the bios hasen't been flashed.

The lite-on is on the second ide with my plextor cd writer.
I'm gonna try the suggestion of putting the lite-on as slave

I will let you guys know if it worked

Thanks for the repond
