  • MBR layout - Four partitions maximum

    GPT layout - Windows currently limit number of partitions to 128. This may change in future.

    See the info below.

  • Thanks Les52

    Ok so four primary partitions is maximum

    and from one extended partitions how many maximum number of logical partitions one can create.

  • Hi Durgacharan,

    I didn't find authoritative answer on the web, so I tested it myself in a virtual machine.

    I finally gave up when I reached the count of 347 logical partitions.

      Partition 339  Logical             10 MB  3720 MB
      Partition 340  Logical             10 MB  3731 MB
      Partition 341  Logical             10 MB  3742 MB
      Partition 342  Logical             10 MB  3753 MB
      Partition 343  Logical             10 MB  3764 MB
      Partition 344  Logical             10 MB  3775 MB
      Partition 345  Logical             10 MB  3786 MB
      Partition 346  Logical             10 MB  3797 MB
      Partition 347  Logical             10 MB  3808 MB

    DISKPART> create part logical size=10

    My virtual system could create more.

    I set up a text file that I used with diskpart command.

    diskpart /s diskconf.txt

    diskconf.txt
    ========

    select disk 1
    create partition logical size = 10
    create partition logical size = 10
    create partition logical size = 10
    create partition logical size = 10
    ...

    However, performance may be a problem. I did not test performance with so many logical partitions.

    If you decide to test for yourself, please post your results. I'm curious too.

    Good luck
