When I bought my pc I had a Sony DVD Writer, DW-Q28A (master) and a Sony DVD ROM DDU1615 (slave).
My DVD Writer broke so I bought a new one, Sony DW-G120A. I set it to master, just like the broken one I removed was set.
When I started my pc (Windows XP Media Center Edition) the new drive got recognised but the DVD ROM which was working fine before and which I didnít even touch is not recognised anymore. I checked for loose cables but that isnt the problem. Any ideas on whats causing the problem?
