Windows 10: Cannot format WD 1TB HDD

    Cannot format WD 1TB HDD

    I bought a new WD 1TB HDD and was running install/format when I had a power outage.
    When power came back I could not format this drive.
    The drive shows in Device Manager but fails format there and every where I have tried.
    I used UBDC and have not been able to format in any of the Partition tools.
    Computer Management/Disk Management shows:
    Volume: E
    Layout: Simple
    Type: Basic
    Filesystem: RAW
    Status: Healthy (Active, Primary Partition)
    But its not formatted.
    I have been trying to format as NTFS.
    I have deleted the partition and created it several times.
    What next?

    Have you tried diskpart to see if appears there, you can also use diskpart to clean the drive ready for initialising.

    1. Command prompt w/ administration rights.
      • Type in "DiskPart" in command line.
      • Type in "list disk" in command line to show all disks in this machine.
      • Use "select" to set the focus to the specified partition.
        For example "select disk 1".
      • Use "clean" command to remove GPT disk from the current in-focus disk by zeroing sectors.

      1. Go back to Disk Management, you can see GPT disk is "Not Initialized" now.
      2. Within Disk Management, right click on disk info, choose "Initialize Disk", You can see GPT disk is "Unallocated" now.
      3. Right click on disk info, choose "New Partition…", follow Partition Wizard and format it.

    I've used UBCD/Ultimate Boot CD on occasion but mostly use the bootable GPARTED LiveCD to clear partitions and put the drive back to its as-shipped [from the manufacturer] condition. GPARTED uses a version of Linux as its OS.

    Perhaps the Drive was locked when you had the power outage ? so was no unlocked when the format finished....

    Did you ask on WD Forums?

    I think MHHD is one Program that can potentially Unlock it again , I also use their HDD LowLevel Formatter Tool as well. I have used 4.5 version only of MHDD. (see older versions below)


    Q: Can MHDD work with USB drives?
    A: Theoretically yes. You have to find a driver which turns your USB device into SCSI (under DOS). Then MHDD can work with your device in SCSI mode. The driver is located here: ... OS-Driver/
    There is also a very good boot floppy disk available here: ... Boot-Disk/

    and see the Security Commands here


    MHDD 4.5 = still need the password to UNLOCK, but it tells you everything you need to know about the state of the locked drive. Run from a bootable ISO cd or USB key. DONT USE VERSION 4.6 that is in Hiren’s Boot CD. GOOGLE AND FIND VERSION 4.5. Google the file mhdd32ver4.5.iso, and create a bootable cd or usb out of it.

    1. plug the drive into an older sata motherboard computer if possible.
    2. set your BIOS sata controllers to the most NATIVE and non AHCI or RAID mode you can. ( use IDE)
    3. Boot to your mhdd iso cd that you created. This sets the DOS environment and memory manager and stuff.
    4. MHDD -> press Shift+F3 and choose your drive. if its not listed then either edit \mhdd\cfg\mhdd.cfg to enable the controllers or use another computer/motherboard/controller.
    5. MHDD -> Press Shift+F2 to view the drive properties, it should say LOCKED if so.

    Some default Passwords for different brands:

    SEAGATE -> “Seagate” +25 spaces
    MAXTOR series N40P -> “Maxtor INIT SECURITY TEST STEP ” +1 or +2 spaces series N40P -> “Maxtor INIT SECURITY TEST STEP F” series 541DX -> “Maxtor” +24 spaces series Athena (D541X model 2B) and diamondmax80 -> “Maxtor”


    FUJITSU -> 32 spaces
    SAMSUNG -> “ttttttttttttttttttttttttttttttttt” (32 times t)
    IBM series DTTA -> “CED79IJUFNATIT” +18 spaces series DJNA -> “VON89IJUFSUNAJ” +18 spaces series DPTA -> “VON89IJUFSUNAJ” +18 spaces series DTLA -> “RAM00IJUFOTSELET” +16 spaces series DADA-26480 (6,4gb) -> “BEF89IJUF__AIDACA” +15 spaces
    HITACHI series DK23AA, DK23BA and DK23CA -> 32 spaces
    TOSHIBA -> 32 spaces For xbox hdds try “XBOXSCENE” or “TEAMASSEMBLY” too
