Hi ayfujis and welcome.
Have you installed any programs on the Vaio? Some Virtual Disc software causes problems with the drive selection.
After how long do you get the error message?
What exactly is the error message you see?
Have you tried a different make and type of disc? Most use Verbatim, Sony or TDK DVD+R discs to prevent accidental deletion.
Which Vaio Model do you have?
If all else fails, all you can do is phone Vaio support for advice.
