  1. Formatting a mirrored 6TB disk not possible?


    HI,

    I need to format two 6TB hdd as mirrored disks. These disks are not used as OS, just for data.

    The disk manager goves me an error message: "The action is not possible for the object". I can only format it as simple disk or as minimized disk.
    I am using several mirrored disks up to 5TB and never had a problem in formating them.

    My PC: Dell XPS8300. Windows 10 Pro; Icy Box with USB3 connection.



    Does anyone have an idea what is wrong here?

    Thanks in advance

    :)

    How can I partition a 6TB HDD in Win 10?


    No need to use third party partition. Open Admin command prompt:
    1. Diskpart
    2. list disk
    3. ========>Take a note of disk numder for the 6TB drive
    4. select disk # ====> # from step 3
    5. Clean
    6. Exit
    7. Open disk management. A windows popup. Select GPT to initialize.

    How To Format A Write Protected Flash Memory ?

    ¿You already tried this one?...

    Run CMD


    1. diskpart
    2. list disk

    Then in the 3º step, put the correct number of disk in the list for the usb flash (if it's listed in disk 3, then you'll have to write select disk 3).

    2. select disk #
    3. clean
    4. create partition primary
    5. select partition 1
    6. active
    7. format fs=fat32
    8. assign
    9. exit

    with that commands you will format the flash drive in fat32, if you have a large drive you can select also "format fs=ntfs" in step 7.

    good luck!

    Formatting a mirrored 6TB disk not possible?

    How Long to Full Format a 6TB Drive?

    I finally found an answer to my original question.

    When HGST Technical Support was in San Jose, California, the engineers were extremely knowledgeable. Unfortunately, after Western Digital acquired HGST, HGST technical support was moved to the
    Dominican Republic. They seem unfamiliar with their hard drives. For example, I phoned about a HGST Deskstar NAS 6TB drive. The support person told me they did not have such a product. How can you not know about your own products.
    Ugh

    I then emailed asking, "Using the Windows 10 Disk Management snap-in with Full Format (Not Quick Format), how long does it take to format a HGST
    Deskstar NAS 6TB drive?" They replied to say a few hours. Obviously, a wrong answer.

    I phoned their competitor - Seagate. The Seagate engineer was located in California. He knew the answer immediately. He was very knowledgeable about this question and several others.

    Around 12 hours / 1 TB, so 6TB is ~72 hours (3 days)

    He also said that for their archive drives, Google does a Full Format for all their new hard drives. So even though the OS will auto mark bad sectors as it encounters errors, doing a Full Format is a more thorough verification according to Seagate.

    It turns out that the motherboard SATA port which I was using had a read/write hardware issue. This explains the reason for the slow formatting of my new drive as you originally suggested.

    Thank you for your help.
