I put this PC together a good while ago now and I have two optical drives in it, a brand new NEC DVD±RW burner AD-7173 IDE and a DVD/CD-RW which i pulled from my last system. Today being the first time i even used the new drive I have noticed its not working. It will not see any CD or DVD i put into it nor will it allow me to burn anything. The drive was set as a secondary master on the same cable as my other drive (mobo only got 1 IDE slot) So i set the new drive to master and removed the other drive just to be sure it isn't a connection problem. This is really driving me up the wall, it should work everything says it is working but it just will not see a blank disk to write to. And just in case you are wondering the drive supports DVD+R and theses are the disks I am using. I even tried to flash the firmwire and but that failed which is making me think there is something major wrong.
