If so, that is normal, sorry to say. The ASMedia SATA chipset and driver does not support ATAPI devices, and all optical drives are ATAPI devices. They are connected as standard SATA drives are, but the actual interface is different. I can't find the official fine print about this now, but this is true, sorry to say.
Are you using the ASMedia SATA driver on the ASMedia chipset? If so, you could try changing to the standard Windows AHCI driver, but I cannot guarantee that will make any difference.
Otherwise, you'll be stuck using the Intel SATA ports for your optical drives.
What kind of drives are you using in that PC? All or mainly HDDs?
