DVD burner stopped working

[sheryl]

I just had a new computer built and included a DVD CD rewritable drive. I was able to burn a DVD and CD once each and then it stopped working. It won't even recognize anything when I put any type of disk in the drive.
I get unknown device or drive not ready when I try and put a blank DVD or CD in the drive.
The burner is a Sony DVD RW DW-U14a.
Did I buy a lemon?
I'm using winxp.

"Did I buy a lemon?"

Sure sounds like you did...

Download the freeware DVDDecrypter 3.1.9.0 and install and start it up and see what it says (it is something of a sleuth). There is a setting build scsi/atapi device map, which you could try.
