Sony dvd rw

hi folks,]

recently i purchased a new system core2 duo. but i utilised my old dvd-rw sony since it was hardly 6 months old. in my old pc, this dvd-rw used to detect all cds and dvds. but after putting it in d new system it detects only the cds but not the dvds… plz can sum1 help me out with this, ill be very thankful

Hi and Welcome!

could you please provide some information about the motherboard of your new computer and also about your DVD-RW drive?

As for the detecting of discs - could you please describe the problem more detailled?
Can you read plain data DVD discs (or browse a video DVD using a filemanager like Explorer)?
Are there any error indicators in Device Manager (assuming you are using Windows)?
