They are used for the file-system. The OS needs e.g.some information, on
where the different files are on the disk. On an MS-DOS formatted disk,
this information is written into the FAT, the file allocation table. This
logically takes up some space on the disk

Same here, although it's AFAIK not a file allocation table, but the inode
table and the superblock backups.
