    Hi all,

    I've just bought one 3TB Internal Hard drive to replace a old one. I use this hard drive to install Operation System ( Windows 8.1 Pro ). When I create partition ... It can only detect the maximum of 2TB ....I can not see the rest of it. My question is How can I create partition for the rest of 3TB Hard drive please ?

    Thanks for your concern and help.

    You need a UEFI system & need to format the HDD as GPT.

    check your bios about handling certain volume sizes of hard discs

    you need to convert the partition style from MBR to GPT otherwise the MBR limit is 2TB per partition

    From an elevated command prompt

    Type diskpart then hit Enter
    Type select disk X then hit Enter (where X is the number of the DISK DRIVE you are trying to convert, be careful not to make a mistake here)
    type clean then hit Enter
    type convert gpt then hit Enter

    Now you can create the full 3TB partition

    Sorry, UEFI isn't supported by this old mobo. It would be better if you use a smaller HDD for booting & use the 3 TB one for data storage by formatting it in GPT style.

    1) check your BIOS, go in to BOOT menu, then see if boot mode is set to UEFI or Lefacy or UEFI with "Load Legacy ROM"

    2) to check if a disk is GPT or MBR

    From an elevated command prompt

    Type diskpart then hit Enter
    Now Type list disk then hit Enter
    all the disks connected to your computer will be displayed, the ones that have an * next to them are GPT disks, the ones which don't have an * are MBR disks.

    no UEFI support on this mobo. You must have missed Tito's post after he checked the mobo :D

    @Tito & J-Lawrence

    One more question, If I want to use this 3TB as storage, not Operation System, How can I format or convert it to GPT with windows 8.1 Pro x64, please ?

    Right click Start button > Disk Management > Click on your 3TB HDD the whole way to the left > Right click on it > Convert to GPT Disk.
    Then you need to make partitions but not sure of this as I've always used third party tools for partitioning.
