Toshiba 3TB Partitioned As All MBR?

  1. Hi, I run Windows 7 Pro SP-1 64-Bit with a ASRock P67 PRO3 (B3)

    MoBo that has a UEFI BIOS.


    My C, D and E partitions are on a 120 GB NTFS SSD with a MBR.

    I installed Windows 7 on a pre-partitioned SSD, so no hidden

    "System Partition".


    I installed a Toshiba PH3200U-1I72 2TB HDD that is Advanced Format

    512e and is properly "Aligned" using the Toshiba provided utility.

    The PH3200U-1I72 is used as storage only on partitions "F" thru "M"

    set as MBR and working perfectly.


    I bought a Toshiba PH3300U-1I72 3TB HDD that is also Advanced

    Format 512e to replace the 2TB.

    I know that 3TBers can't utilize the full capacity in MBR,

    and must be set as GPT to do so.


    BTW: I would make 5 partitions, 4 NTFS and one small FAT32.


    I use Norton's Ghost weekly and it has issues with GPT.


    I proceeded to contact various partitioning/cloning software

    companies to see if their products could be used in place of

    Ghost.


    The partial exchange below is between TeraByte Unlimited and me:

    TBU:

    "If your new drive uses 4K sector sizes you
    wouldn't need to have a GPT."

    Me:

    Please elaborate.

    BTW, This is what my present Toshiba 2TB looks like:

    BPS 512 BPPS + Cluster 4096.jpg

    TBU:

    If you expose the 4K sector size and not the emulated

    normal 512 byte sector size, you can use an MBR and

    use the entire space (up to 16TiB).
    0xFFFFFFFF*512=2,199,023,255,040
    0xFFFFFFFF*4096=17,592,186,040,320


    Me:

    With what software and what is the procedure to go about

    doing this?

    Can it be done via a Bootable CD or must it be done in Windows

    with just my SSD and empty 3TB connected?

    TBU:

    It would be a drive feature/option, typically using
    a jumper. The BIOS would also have to support the larger
    sizes too so it doesn't crash reading larger sectors, a
    modern BIOS should be able to handle it.


    My hunt for answers from Toshiba is a lost cause as their

    support is a TOTAL joke and does NOT offer E-Mail support.

    So, I'm here to find out if this "exposing the 4K sector size" can,

    indeed, be done to my PH3300U-1I72, and if so, EXACTLY how to go

    about doing it.

    Also, are there any shortcomings to having the Toshiba "exposing

    the 4K sector size" using 5 partitions, 4 NTFS and one small FAT32?


    Thanks in advance for any help you can be.

    Big Al
