dvd rw drive (E:)

Hi, I have a problem, my DVD RW drive (E does not play any disk (movie, music or any type of blank disk). It used to but not any more. when I right click the DVD RW drive icon then click properties, in the general tab is shows type: cd rom and file system: unknown. I then go into the hardware tab and it says that my pioneer DVD RW-DVR-k17rs ATA device which is what type of drive it is, is working properly. However, when I put any disk in it, it either automatically ejects it or I get a insert disk message but the disk is in the drive. By the way I have windows vista basic as my operating system.
