    Windows 10: Unknown System (ZNot Initialized and Unknown Disk (Cannot go Online) :) Partition or Disk.

    Hi Leonardo,

    There are several factors why you see unknown system partition or disk in your computer. It can be a recovery partition. For us to better assist you, we'd like to gather more information:

    • What troubleshooting steps have you done so far?
    • When did this issue occur?

    Meanwhile, we suggest to follow these steps:

    • Open a Command Prompt as admin.
    • Type in diskpart.
    • Type list volumes.
    • Find out which volume shows as your drive E: then type select volume N, where N is the number that the volume was given.
    • Double-check that you're on the right volume, type in "list volume" and check where the asterisk is. If it's beside the volume you wish to change, then good, if not you'll need to do "select volume N" again.
    • When you're sure you're on the right volume, type in remove letter=E.
    • Check it has been done by typing "list volume" to see the results.
    • Close the command prompt window.

    It will let you remove that partition.

    Let us know if you need further assistance.

    Not Initialized and Unknown Disk (Cannot go Online)

    Cannot Format HD


    Need to initialize it as GPT disk type with HD > 2TB:
    From Admin command prompt:
    1. diskpart
    2. list disk =====> Take a note of disk # for the 4TB HD
    3. select disk # ====> From step 2
    4. clean
    5. exit
    Open Disk Management and initialize the disk as GPT, create simple then format.
