(2) LBA mode
Logical address assignment in the LBA mode starts from physical cylinder 0, physical head 0,
and physical sector 1. The logical address is advanced at the subsequent sector from the last
sector of the current track. The first physical sector of the subsequent physical track is the
consecutive logical sector from the last sector of the current physical track.
Figure 6.6 shows an example of (assuming there is no track skew).
