I had posted a similar query sometime before.. Sminlal and Malmenal helped me out immensely there.. Although I could not get the Asus drive (the one suggested above), I got hold of a Lite-On iHAS324.. Now I consider it one of the best purchases I ever made.. There are newer versions available.. Am still on the look out for that Asus drive though.. Partly because I need to keep two optical drives for my purpose..
