So I just build my first pc, put it together last night. I have three drives I'm connecting to the SATA3 ports on my motherboard. (its the asrock z77 extreme4). I have an optical drive, a westerndigital hdd, and a kingston ssd. When I first hooked them all up, they were all three visible in boot options in BIOS. I installed windows onto the ssd, from inside windows it could see the hdd but not do anything with it. I turned off the computer and opend up BIOS but now only the ssd and optical drive are listed. In the system browser it still shows the three drives conneted but the hdd is not listed in the boot options. When I get back into windows it cannot even find the hdd. I have tried conntecting them into different SATA3 ports but to no avail. If I disconnect all the drives except the hdd, then it will show up in the boot options, but that doesn't do me much good. Please help!
