Well I just built my first gaming rig and have not been able to get both hard drives to show up. I have a Asus Sabertooth z77 motherboard and have an HDD drive and an SSD. When I plug both drives up the SSD drive is the only one that will show up in the EZ mode of the bios but the HDD will show up in advanced mode. Also, when I unplug the SSD, then the HDD shows up. WTF. I installed the operating system on the SSD and the HDD will no show up in windows 8 in my computer so i figure it has to do with something in the bios. My SSD is only 60 gig because all i planned on doing is running the operating system on it. If anyone is familiar with asus bios and has any idea how to resolve this problem please help. Thanks
