ATAPI DVD/CD Rewritable Drive

Hi, I am having a proble with my Atapi DVD/CD drive.The device manager is showing a yellow mark above it and I understand that this means the device is not working and its not. Tried downloading a driver update but Microsoft state that the best driver is in the computor. The device is showing a code 10 fault. Has anybody any ideas what I need to do or does it mean a new drive unit? Thanks, regards, guitarbobi
