If you search the forum you will find other similar posts, so I am not the only one with this problem. I don't think it is motherboard specific, but in any case I am using a Gigabyte Z97 motherboard. The optical drives are installed on ports 2 and 3 (an SDD and a HDD are installed on ports 0 and 1). Moving the optical drives to different ports does not help. I can not find a SATA transfer mode setting in the bios and I am using AHCI. I believe QPxTool is for Linux and not Windows.
