ACER DVD Drive Code 10

The drive in my laptop is an HL-DT-ST DVDRAM GSA-T20N ATA Device. It was okay until yesterday. Today it will not work. The device manager shows that there is an issue with the drive. It shows that "This device cannot start. (Code 10)". I have tried to update the driver, but am told that the newest version is installed. Any ideas? Thanks
