WD 1TB HDD won't show up in Win8.1

I finally got Win8 installed. Everything is great besides my HDD isn't showing up. I've looked at a bunch of different threads about how to fix it in Disk Management, but I can't find a way to do it. I don't have an options to do anything that they say to do. Here is what I see in disk management. It shows up as disk 0 and unallocated.

No right click:


Right clicked on drive:


Thanks!

    Let's try the command line equivalent of Disk Management (which is sometimes more powerful), diskpart. Right-click on the start button to bring up a menu and select Command Prompt as Administrator (click OK to the security prompt). Type "diskpart" into the prompt to load the utility.

    Use these commands in diskpart:

    "list disk" to view disks
    "select disk X" to select a disk to work on (where X is the number of the disk in question. It should be the same number that shows in Disk Management, in the pictures disk 0
    "create partition primary" to create
    then
    "format fs=ntfs quick" to format
    "assign letter = x" where x is a drive letter of your choosing

    IF there are any error messages here this should help us determine the problem (post any errors)
  2. It may also be that this system needs the disk to be in GPT mode. Does the disk work if you select "convert to GPT disk" in the right-click
  3. Yes I just converted it to GPT disk, and all the options are still the same as before.

    That worked!! Thank you!
  5. Does diskpart get you any further? If it fails at least it should provide clues in the error messages
  6. ah, posted too slowly. Glad it worked.
