My DVD-RW drive reads DVD, but not CD

[Thunder1177]

This happened while burning Audio CD, at the end of process, in leadin/leadout phase Nero showed write error. Before then i burned few cds at max speed without problems. Now it even doesn't recognize CDs. But works great with DVDs. Any suggestions ? Its Sony DVD-RW DWQ28AWG
