Even if it contains no ordinary files, your /Home filesystem still contains
- The "." directory,
- The "lost+found" directory,
- Your home directory.
The minimum size for a directory file is 1 block (typically 4 KB), and the "lost+found" directory is usually pre-allocated with more space (16 KB) so that
fsck can link lost inodes there without having to allocate more space from a possibly corrupt free block list. Even a newly created filesystem is never completely empty.
