Hard Drive is not detected during POST but the Hard Drive itself is running.

Hello, I am building a gaming PC and I am new to building computers. I am having trouble with my Western Digital 1TB HDD in that the computer will not detect it during the POST, yet the drive itself is vibrating. Also the activity light on my case does not light up even though the HDD header is plugged in to the MOBO. (It gives the same message whether it is plugged in or not when I turn the computer on.) I have both the SATA cable and power connected to it, and I know the cables work because they work on my optical drive. Is my HDD DOA or is there something I am missing? Thank you!

My Build:

Case: Thermaltake Chaser A31

CPU: i7-4770K, COOLER: Hyper 212 Evo

MOBO: GIGABYTE Z87X-D3H

RAM: Corsair Dominator Dual Channel 8GB

GPU: ASUS GTX 780

PSU: Corsair CX750

Samsung Optical Drive

Western Digital Blue 1TB HDD

I would very much appreciate any help; this is keeping me from accessing the BIOS and installing Windows 8.1

  1. What ports do you have it plugged into?
  2. I have two SATA ports plugged into my motherboard, one leading to the HDD and one leading to the optical drive. The power cords are connected to the two components respectfully, since they are the same. There are 6 SATA ports on my MOBO, does it matter which ports they are plugged into?
  3. I thought maybe your board had 2 controllers, but I see that it does not, it should not matter where the drive is plugged in, it should find it. It may be that the drive is bad. Is your optical drive being detected okay?

    Well it will open and close when I press the button to, so I would think that it is working. I tried POST again and I noticed that the HDD is making a very bad sound, like a rattling or maybe a grinding type of sound. BTW, the message on screen tells me to "Reboot and select a boot drive" or something like that, so I can't even access the BIOS.
  5. Opening and closing the door only means it has power to it, nothing more.
    "Reboot and select a boot device" does not mean the drive is not working either, it means that there is no bootable operating system being found, which is perfectly normal if you have not installed the OS yet.
    You need to enter the BIOS and disable the splash screen, so you can see what is actually going on during POST.
    What happens if you put your Windows install disk into the drive and then boot?

    I tried putting the Windows disc in and it did the same thing. Could you tell me how to enter the BIOS and disable the splash screen? whenever I press any keys it just repeats the message, and I do not get any prompts to enter the BIOS like what is shown in my motherboard manual. Thank you!

    You press the delete key, page 59 in your manual starts explaining how to enter the bios, and set up your SATA devices.
    Do not wait for the POST screen to tell you to hit delete to enter the BIOS, if your splash screen is enabled, you won't ever see any of these messages. Just start tapping the delete key over and over, about 1 time a second as soon you turn the power on.
