The more obvious reason is that you always need to store metadata such as filenames, dates, subdirectories, etc. Neither of those formats is able to achieve that nominal amount when you sum the sizes of the files stored on disk. The IBM-PC format also stores 512 bytes per sector, but only 9 sectors per track (on a Double Density (DD) disk, as opposed to a High Density (HD) disk), also double sided, also 80 cylinders per disk, which yields 80 * 2 * 9 * 512 = 737280 bytes = 737.28 kB = 720 KiB raw block data. 2 tracks per cylinder) with 80 cylinders per disk, which makes 80 * 2 * 11 * 512 = 901120 bytes = 901.12 kB = 880 KiB raw block data. The Amiga disk format stores 512 bytes per sector, 11 sectors per track (a track is one side of a cylinder), double sided (i.
