I'm trying to install a second DVD reader into an early 2008 Mac Pro. It's an IDE interface. I've tried two drives now, a LiteOn iHAP422 and a Pioneer DVR-A18M. I've tried setting the jumper to CS and Slave. In all cases, when I mount a DVD in FairMount, it shows 900+ bad sectors. The same DVDs show no bad sectors in the existing SuperDrive (Optiarc something) or an external USB mounted drive. Anybody have any ideas what's going on here? Thanks.
