Dvd cannot read cd

recently,my dvd (mida 16x) stopped reading cd,s. it can read only the windows XP home.I tried other cd’s like Epson that came with my printer and scanner and no luck.when I lick on properties I see 0 bytes used,and 0 bytes free as if there is no cd in the drive.it reads and plays all dvd’s.
do you have any suggestions?
thank you.
