I had to format my HD and I had it upgraded to XP Pro. The guy who did it also installed my drivers. Here is the problem. When I use my DVD drives (I have 2 one is DVDRW) If I use it twice in a row, for instance copying mp3's that were on my previous hd, it locks up. I am not sure if he installed the drivers for my dvd drives. Here is a brief description of my setup.
I have a Sony Vaio PCV-RS 530G
