Just finishing the build on my first computer. Whatever I have tried I cannot get the BIOS to see the WD HDD. My mushkin 240 GB SSD is working fine. Hardware: ASUS P8 Z77 V-Pro MB, 16 G RAM, EVGA GeForce GTX 760 2 GB, Corsair HX 750 PSU, Corsair H80i cooler. I have plugged the HDD into everything, changed cables, yes, tried using the cables/ connection at MB that works on SDD and tried booting and no HDD is seen. THe only thing I haven't tried is making an avocado bacon cheeseburger for it. Any ideas before I RMA this or have i just a DOA HDD? Yes, sata cnxn, 6.0 G
