This is my second drive in nx6125 lap-top, i replaced it after 6 months of use, it just “died” during burnin with Nero. Now with this second i have problem with writing cd and dvd (everything was ok until now, i’m using it for 8 months) it cannot recognize it after burning… It can read some old cd’s and dvd’s. I tried to find firmware but i couldnt find it anywhere exept on VAIO site but i couldnt use the firmware… Is somebody having problem like me? Please tell me how to solve a problem, i am bored to buy a 3rd one…
