    MBR HDD - 2 partitions to fill 4TB drive


    Hi there,

    I somehow managed to partition and format the attached (Disk 7) and both partitions and the HDD overall has been working for a few years now. I need to recreate it on Disk 6 and I can't remember how I did it.

    Anybody know how I did this?!?!

    TIA

    :)

    New 4TB Hard Drive Read As 1.6TB

    The 4TB drive only shows 1.6TB, there always are two reasons for that:

    1.The 4TB hard drive has been initialized to a wrong partition table. If you find a formatted hard drive not showing full capacity, which is mainly because you format the
    4TB hard drive to MBR partition table. As we all know, MBR partition table cannot address to the space that exceeds 2TB. As a result, to use a full capacity of a hard drive that is larger than 2TB, you need to initialize it to GPT partition table
    via
    an MBR to GPT converter    .

    2.The 4TB external hard drive does not connect correctly. Some portable hard drive and USB hard drive are designed to connect a PC via a USB port. If you install the USB hard drive to your computer, the hard drive capacity detecting may
    become an issue. An accepted explanation is the controller board of USB hard drive breaks the 2TB limitation, yet Windows internal device controller does not. Therefore, you need to additional hardware to make the installed USB/portable hard drive showing
    full capacity. In that case, all you need to do is connecting the 4TB USB hard drive via USB port.

    Windows 10 installation on 4tb hdd on GPT partition with UEFI mode system.

    Original Title: windows 10 installation on 4tb hdd

    Hello,

    I have a new Seagate 4tb hdd and gigabyte H110M motherboard (UEFI) in a desktop computer. When I install windows 10 x64 it only shows up as 2tb. I have converted the hdd to gpt partitioning (as apparently this is what I need to do to show whole hdd) but
    when I install win 10 it converts it back to mbr and still only shows it as 2tb. What do I need to do so windows installs in gpt format?

    Thanks

    Troy

    MBR HDD - 2 partitions to fill 4TB drive

    Problems with 4TB HDD

    I tried that, it allows to use only 2TB of drive. Other space remains unallocated and it doesn't allow to create another partition.
