    250MB space used when a new partition is created?

    Hi, just a small curiosity of mine.

    When using gparted, I sam that when I created a new ext4 partition, approximately 250MB of free space was used up. I am curious about what this space is used for?

    Thanks for everyone who can provide me some hints

    All journalled filesystems reserve space, there are already numerous posts on this subject in the forums.

    Respectfully, I am asking because my search terms did not give any answer.

    Also, partitions don't completely butt up against eachother. It's not like this:

    [------Partition 1---------][------Partition 2-----]

    It's more like this:


    [------Partition 1---------]............[------Partition 2-----]


    And then of course, the filesystem itself takes up space, and reserves space for itself. For every partition you create, you lose space due to the gap between partitions and also due to having a separate filesystem on each partition. I'm not saying "don't create multiple partitions", I'm just saying that it's one of the tradeoffs.
    I try to treat the cause, not the symptom. I avoid the terminal in instructions, unless it's easier or necessary. My instructions will work within the Ubuntu system, instead of breaking or subverting it. Those are the three guarantees to the helpee.
