    WIN10 2TB HDD not showing up Disk management


    Hey guys,

    I´ve been googeling this for a few days and can not seem to find the answer. So here goes...

    Problem:
    I have a 2TB seagate barracuda HDD that is not showing up in:
    - disk management
    - CMD -> diskpart -> list disk

    It does show up in:
    - device manager
    - bios
    - Intel rapid storage technology

    Specs:
    CPU: I5 6500
    Motherboard: GA-Z170XP-SLI
    Windows 10

    I also tried switching out cables and ports. Same results.

    Any help or further questions would be awesome. This is starting to piss me off...

    Can you try the HDD in another PC or can you lay your hands on a SATA docking station to test if the disk is a dud or not
    I'm assuming the disk is new, has it ever been working before in any circumstances?

    1)boot up with a windows 10 cd or usb. YOU WILL LOOSE YOUR DATA
    Then type:
    diskpart
    select disk "x" (x is the number of the disk you want to format)
    clean
    create partition primary
    select partition 1
    active
    format fs=ntfs
    exit
    exit

    2) start with a linux cd
    and see if hdd is there.

    3) UPDATE THE FIRMWARE OF SEAGATE .
    google seagate firmware
    click on first finding and then download manager, there insert the serial of your drive and download the firmware.

    1) no joy. Sidenote: during the original windows install a 2 days ago I distinctly remember my 2TB HDD being a possible installation place. Obviously I chose my ssd... When starting the WIN10 install just now, the 2 TB drive is no longer showing up as an install option...
    2) linux install recognizes the drive as a possible installation place
    3) no firmware update

    Im starting to feel that the old fashioned engineering techniques are becoming my last option (i.e.: step 1 -> hit with hammer. Step 2 -> check if problem is resolved. If not, return to step 1)

    DEAR MOTHER OF GOD!!! I found what the problem was

    For some reason, windows used 20 gig of my second hard drive as a storage pool. I do not know how or why... I certainly did not do it...
    When I deleted that storage pool, my HDD showed up in disk management.

    Thanks for the advice guys.

    What exactly did you do to make your hard drive reappear? I've got the same problem as you said earlier, I can't figure it out. Thanks

    Similar issue - 2nd used HD "Not Initialized". How to make it "Online?


    I have a very similar issue. I installed a 2nd used WD 1Tb hard drive in drive slot 1 of my desktop. (Slot 0 has the original hard drive C.
    The hard drive shows up in Win10 Disk Management, but as "Not Initialized". The drive has a lot of data that I do not wish to delete, so I do not want to re-initialize it, nor reformat it. How can I change the status to "Online" so that Win10 recognizes it?

    Also, blogger iseko said in the thread above "For some reason, windows used 20 gig of my second hard drive as a storage pool. I do not know how or why... I certainly did not do it... When I deleted that storage pool, my HDD showed up in disk management.". Any idea how he/she deleted that storage pool?



    (BTW, the drive came from an external WD My Book that I have been using as a backup device. The data port on the My Book was broken, so I removed the drive from the My Book case and installed it in the same desktop that it was connected to externally.)

    The second hard drive shows up in Device Manager and not in Disk Management most likely because it is set up as a storage pool. If this is your issue, it’s an easy fix by going to “Storage Spaces” and delete your storage pool. (Storage Spaces is located inside Control Panel>All Control Panel Items>Storage Spaces.) Your second hard drive will then show up in Disk Management.
