I am having trouble getting a computer to see this drive. It uses the award 4.51 bios. My own computer uses the same bios but it sees it no problem. I am puzzled with this. I have tried everything that I know of. Changed jumper settings, changed data cable, removed all other peripherals such as the cd rom and burner thinking that the power supply wasn't giving enough power for the new drive but still no luck. Maybe something simple I'm not seeing but it has me stumped.
