ok, I have the drive in my sig, and from one burn to the next, I started getting power calibration errors. At first I thought it wasn't getting enough power, but I have a 480 watt psu and only one optical drive. I chose another molex and connected it to the drive. same error. next I thought the ide cable might have gone bad. I got another and swapped it out. same error. then I tried another ide channel. same error. then I thought it was the drive. I swapped out the drive and put in my old burner. same error. no idea what it could be. last possible candidate could be that my mobo has a couple of faulty ide channels or is the burner shot? I don't no Idea, any advice would be appreciated.
