- Yes, the same format is used on both sides. However, consider that when you
- flip the disk over, it effectively rotates in the opposite direction. If you
- use U0>H1 to access the second head, the disk will be rotating in the "normal"
- direction, thus making it impossible to read when flipped.
- Does that make any sense? :-)
