Ok, I just WANT to make SURE that the drive, "Sony DVD RW DW-Q120A"  is just a DVD drive and not a DVD Burner, I just need some reaffirmation since I couldn't FIND much info about it online. BumpIt's a burner.
What is the issue ? ?
It's old enough to be failing...Well its not burning DVD's any more, only reading them, from what I thought from the few online sources I could find that it was just a DVD drive capable of only reading and playing DVD's and CD. I thought it could not burn other DVD's. The drive belongs to one of my friend's desktop and he SAYS that the drive doesn't Burn DVD dics. He has a secondary CD burner to burn CD's but when he tries to burn DVD's the drive doesn't reconize blank DVD's. I'm pretty sure it's not the type of DVD, the drive doesn't reconize blank +/- RW, +R or -R Well it doesnt recongize blank DVD as  DVD it thinks it is a CD and when one clicks on the drive with a blank DVD in it you get an error message. He said that before he installed the second CD drive he was able to burn DVD's but could not remeber for sure. So maybe it has something to do with BIOS settings? Also after he installed the secondart CD drive his front USB port and audio inputs don't work only the rear do.Replace it...BRAND new Dual-layer burners are about 35 Bucks shipped right now from newegg...yeah, I got a new one, Sony Optiarc DVD±R DVD Burner. Sorry for the late reply.
