it probably is reserved space, I discussed this subject a few days ago with someone else. You're using a journaling file system like ext3 or ext4? And not surprisingly, it's about the same percentage again, roughly 5..6% of the partition.

Thanks for pointing it out. I haven't noticed it before. Just looked at my system and it's kind of similar.

ok so if it is unreserved space (as you say) do you know if there's a command to 'unreserve' it?

yes, that's easy: Reformat the partition and use a filesystem without journal, e.g. ext2.
But be aware that it will be less robust and more subject to damage or corruption.
