I recently replaced the DVD ROM Drive of my HP Pavilion 750 uk PC with a Sony AW-G170AB2 DVD Rewriter. It wont play CD Albums. Incidentally, it did’nt come with an installation CD. I’m sure I have configured it properly i.e. Master/Slave on the IDE cable. Do I maybe need drivers and where can I get these. The Sony site does’nt seem to be very helpful. Thanks.
