    Only 3 Primary Partitions, Disk Management windows 7 and 8

    Hello to all!

    Why windows 7 and windows 8 introduced a limitation when using Disk Management, and is NOT possible to create more than 3 Primary Partitions?

    However, using DiskPart from command line it is VERY possible, no warnings or notices.

    Leaving DiskPart...

    As far as I know, there is a maximum of 4 Primary partitions on a hardisk, or 3 primary and one extended, and IN the extended partitions more that 4 logical drivers.

    However, from any disk utility like the old, deprecated, and buggy Partition Magic, acronis disk partition utility, gparted Linux, parted, cfdisk, fdisk, or even on the older Windows like Xp, nt, 2000, 98, me, ms-dos, freedos, I WAS ALWAYS BEEN ABLE TO CREATE 4 PRIMARY PARTITIONS, but with the new WINDOWS 7 and the new WINDOWS 8, it appears this limitation of only 3 PRIMARY PARTITIONS instead of 4. Don't know about Vista as I have skipped that version of windows on every PC that I have build or worked.

    What has changed?

    Is this a BUG?

    Or is working like this because of some hidden reason which I can't figure out by myself what could It be, and the only thing that I can observe is that while technology is evolving (hardware and software), we have limitations like this, to create only 3 primary instead of 4 primary while using Disk Management from administrative tools or right clicking on the computer and "manage" console.
    Personally I am a little irritated/annoyed that now the disk management is having "handicap" and I can NOT find a serious reason for this idiocratic limitation. As we are "evolving" the normal path It would be more normal to be able to use more that 4 primary on a hardisk, from my point of view, not limiting to ONLY 3 Primary.

    Maybe there already are 4 primary partitions and you're thinking only 3?

    Let's see a Disk Management screenshot, if interested in posting one.

    I recommend latest Acronis Disk Director to manage partitions. Others on here seem to like Easus products.

    1) I will try to make a video screen capture of the screen with Disk Management as it will be more conclusive if you people don't belive me that using DiskManagement from Win7 && Win8 after making 3 primary partitions will make automatically the 4 partition logical/extended. I already tested this on 3 different hdd after wiping them off, (150 gb notebook, 320 gb sata, 1 tb sata).

    2) I am very curious if this limitation is due:
    - A Bug in Disk Management for Windows 8 and 7


    - due a very known/unknown/solid/hidden/etc reason.

    What happened with Disk Management? Why on XP works to make 4 primary and on the newer Windows don't (it makes automatically an extended one.) Did some coder/tester forgot something or this limitation comes by the default design? If so, why the new design is to assing only 3 instead of 4?

    3) Thank you for suggestion but I don't need an alternative or third party tool to make 4 primary on my hardisk and I am aware that I can use third party utiliy like Acronis, Easus, fdisk, gparted.
    I am an experienced user, I used over the years, a lot of operating systems from the older ms-dos with dos commander and games like Prince, Maze, commodore 64, with basic from the tape etc. to unix-es, linux, freebsd, haiku, beos, os/2, mac, win95,me,2000,nt,xp,win7,win8). I guess that I have skipped only Vista and android,symbian,windows mobile.

    So, I can make the 4 primary in windows 8 and 7 from the command line with DiskPart, or a third pary software BUT NOT with with disk management. WHY?

    If you would have posted the Disk Management screen like I suggested, you'd have the answer.

    When you install Windows 7 or Windows 8, the installer makes what is known as the system partition which keeps the boot loader files. It also makes the boot partition, with Windows (a.k.a. %systemroot%), programs and user folders.

    Dude... no... You are getting it wrong, It doesn't matter if you are partitioning the internal hardisk on which resides the operating system or the external, or secondary internal hardisk. I am not talking about the boot partition here... For example, the secondary internal or external hardis dose NOT need an BOOT partition with files for booting.

    I dunno.

    A few ideas are motherboard bios update might help, installing the proprietary driver for the storage might help


    if you freeze the video at say 7:50, you can see that all the partitions you just made say "formatting" still.

    What happens if you reboot the machine before making that 4th partition? Any changes?

    You could also try making partitions with no format at all, until they are all made first.

    I created 3 primary partitions, with no file system format on them, and no letter assigned.
    After this step, I rebooted, and I did the 4 partition in the end of the hdd where the space was unallocated.
    The result was to end again in an Extended (logical) partition, not in a primary one.

    These days I Will try this on another computer (a friend computer), which has more powerful configuration in his gaming-workstation desktop pc. with windows 7 sp1.
    But I assume the same thing will happen. There is a limitation or bug in disk Management.

    Haha thank you.

    I think it's not a bug. If the Disk Management let you make 4 primary partitions, then you could never make any more partitions after (without deleting one).

    It is by design what is happening I'm fairly sure.
