Western Digital secondary hard drive not recognized

I just installed a brand new 2 TB WD back-up hard drive. I went into BIOS, and I turned on the SATA port. When I go back into BIOS to check that port, it says there is a Western Digital device of unknown size attached to it. However when I go into My Computer and Disk Management, neither of those recognize any hard drive other than my primary hard drive. I'm unable to format the drive or assaign a drive letter because I cannot see that drive in Disk Management. I hear the hard drive spinning right when I start my computer, but the spinning stops by the time Windows Vista intitializes. Neither hard drive has the jumper for master and slave drives, but, unless I'm mistaken, I understand I don't need to worry about those for SATA hard drives. Can anybody please help me fix this problem?

  1. So, SATA drives don't have master/slave/CS jumpers like PATA drives do.

    Usually new disks come with utilities form the manufacturer. I would check the WD website to see if there are any tools for new hard disks.
  2. What mobo are you using? Is it a very old one? Is the bios up-to-date? As long as the bios doesn't recognize the size of the disk, you will not see it in windows right.

    I have a Dell XPS 420. I just updated the BIOS to the latest version, and it still shows the capacity of the new drive as unknown in the BIOS menu.
  4. First of all with all issues like this, "Have you tried another SATA socket?", if not, go ahead and try another, if that doesn't work, try them all. I know on my old Desktop build only every other one worked, unless the first one in the socket was plugged in or some bullshit like that, I think it was trying to do a raid initialization.

    Next question would obviously be have you tried unplugging all HDDs except the one you want to test? If so, does that work? Lastly would to be to try it in another operating system, as, I've had issues with HDDs working in windows and not in lunux & visa versa.

    If by any chance you happen to have a RAID card lying about, or another MOBO (Hopefully the first option) then go ahead and test that too.
  5. I just wanted to thank everybody for your help. I tried what everybody suggested as well as a couple things I found through the Western Digital website, and nothing worked. I exchanged the hard drive for another of the same model, and that new one was immediately recognized by my computer. The first drive I received must have been damaged during shipping. I just wanted to thank those who took the time to help me.
