i have a brand new emachines computer running windows 7 with a ATAPI DVD A DH16AASH SCSI Cdrom drive. i burned some dvds and it worked fine, however i tried burning some cds and it didnt work. i tried updating and it said it was up to date, but the status said "A driver (service) for this device has been disabled. An alternate driver may be providing this functionality". how do i fix this?
