The thing is that the drive does not recognize DVDs anymore. Any program in the computer will not recognize I put a DVD in the drive. On the other hand, computer recognize any CDs i put in that drive just fine.
What I think is that the laser that read DVD is not working anymore.
I wanted to fix this mainly because it's a Sony computer. It has its own cover and I worry if any other DVD drive will fit in.
Thank you for your suggestion.
