Floppy Overhead?

[Vertimus]

I heard the 1.44 MB formatted floppies are actrually 2.0 MB. 0.56 MB went to formatting.

I have a few questions:

1. Why is an outrageous 25% of the disk spent on formatting?
2. How much of the overhead actrually goes to the filesystem? If I formatted the floppy with a different filesystem, i.e. ext2, would it store more data?
3. How much of data-cds are spent on overhead?
4. What about DVDs? Or normal hard drives?
5. Compare the capacities spent on overhead between the following filesystems: NTFS, FAT16/32, Reiserfs, Reiser4, ext2, ext3, JFS, and XFS

They are 1.44mb. 1.38mb is useable... AFAIK. Who uses floppies anymore?

Sounds like interesting homework for your class.
