I would assume it's your Highpoint Raid card. I can't see a Raid card worrying about opticals. Does it mention opticals in the manual?
4-channel ATA RAID Host Adapter
Supports arrays up to 2TB
supports up to 8 hard disk drives
supports RAID 0, 1, 5, 10, JBOD
4 independent ATA 133 channels provide parallel disk array access
You are going to have do some searching for one that works. Usually the method is to move your HDDs to the card (as long as it says it's bootable) and put your opticals on the MOBO connectors.
