17 - Data Block Bitmap
22 - 1 block
25 - 1 block

30 For the special case of block group 0, the first 1024 bytes are unused,
32 The superblock will start at offset 1024 bytes, whichever block that
33 happens to be (usually 0). However, if for some reason the block size =
34 1024, then block 0 is marked in use and the superblock goes in block 1.
