So I've had this Sony K-series Viao laptop for about 2 years now. Recently (past 2 weeks) it stoped recognizing the DVD's i put into the drive, and will not play them anymore. The drive used to work all the time, It is a dvd burner. So what does it sound like is wrong, when i put in the cd, I can hear it spinning alot (sometimes gets very loud) but it never pops up a help screen to ask me what I want to do (used to do that). So when I went to check in "my computer", it shows the D: drive as empty, I tryed clicking on it and it just shows an empty folder. I also tryed opening it in Windows media player and it says "please insert a cd into drive D:." Does this sound like a bad driver, or broken hardware? thanks for your time, and and info you can provide!
