    I have Windows 8 Pro x64. I recently installed a 3 TB HDD and I want to set three different partitions; one for documents, one for music, and one for videos. As I go into computer management I can see the computer recognizes the HDD however in the visual display I can only create two partitions so the third is colored black and says it is "unallocated". When I right click on the unallocated space the only thing I can click on is properties which does not seem to help me now. Anyone have any suggestions??

    I attached a screen print of my Computer Management screen. I have Windows 8 OS on 'Disk 1' while the 'Disk 0' is the 3 TB HDD with 746.52 GB unallocated. I should still be able to access that 746 GB. I'm stumped:confused: I've been playing around with it for several days.

    Did you convert the disk to GPT before partitioning the drive?

    It is set as MBR. With MBR aren't I allowed 4 partitions anyway? If I do need to convert to GPT, what is the best way to convert?

    The situation is really funny and chaotic. But it's not only limited to HDDs. For example, DVDs are sold as 4.7 GB, which means 4.700.000.000 bytes.

    The sooner the new IEC prefixes are adopted worldwide, the better.

    Yet things like RAM are the exact number (1024MB for example)

    actually the count is not 100% 1GB is 1000mb not 1024mb
    sort of like
    111 = 7

    The situation with RAM is chaotic and absurd, just like everywhere else.

    Take, for example, RAM speeds. The modules marketed as "PC3-12800" run at 12800 MB/s (where 1 megabyte is equal to 1000 kilobytes).

    It's ridiculous and funny at the same time. Because there are still really stubborn people who defend the status quo (which is pathetic and deplorable)

    just like others replied use GPT instead of MBR
    ---
    and here the calculation for lost space
    eg. 2 tb harddrive

    1 TB = 1024 x 1024 x 1024 x 1024 = 1099511627776 Bytes
    HDD 2 TB Manufacturing will use number as exactly as 2000000000000 Bytes
    Therefore 2000000000000 (that HDD written) divided by 1099511627776 (1 TB of computer's math)
    We would get 1.818989403545856475830078125 ~1.81 TB :biggrin:

    It's simple really. Transmission speed numbers have traditionally been base-10 where numbers for other computer-related circumstances have always been base-2. It's just the HDD manufacturers who broke that.

    A 1GB RAM stick is 1,073,741,824 Bytes. A 100Mbps network transfers 100,000,000 Bits per second.

    If anything, this KiB/GiB/TiB nonsense introduced _more_ confusion because it doesn't just introduce new units, it redefines existing units. It's complete bulls**t if you ask me.

    If you want to be pedantic, be it. 1 Gigabyte isn't 1000 Millibit either (what's a Millibit anyway?). Capitalization matters.

    And what's with the 111 = 7? Can you elaborate?

    Why not just make individual library folders? Partitioning would be best reserved for other OS' s
