It is possible to gain additional formatted capacity by changing the disk format. For example: 80 Tracks X 2 sides X 15 sectors X 512 Bytes/sector = 1.288 Mbytes (less file system overhead: directory, fat ect.). 80 Tracks X 2 sides X 8 sectors X 1024 Bytes/sector = 1.311 Mbytes (less file system overhead: dir, fat ect.).
