Yes of course I meant analogy.
I can delete all the partitions on my disk. Then I can make a partition & then tag/label it as NTFS. But is does not mean that it automatically created the NTFS filesystem for me. I must use either a linux ntfs tools or windows to make the ntfs filesystem.

Or say I want to use linux filesystems. I can make a partition & set it to Linux, but it did not make a usuable filesystem on it. I must choose to use ext2fs or ext3fs or reiserfs or JFS or XFS.

Analogy: I can label seats for Bill or Linus or anyone else (tagging the partition). It doesn't work until I get Bill or Linus to sit in their chair (formatting the partition with a particular filesystem).
