(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).

6.3 Power Save
The host can change the power consumption state of the device by issuing a power command to the
device.
6.3.1 Power save mode
There are four types of power consumption state of the device including active mode where all
circuits are active.
In the power save mode, power supplying to the part of the circuit is turned off. There are three
types of power save modes:
•
Idle mode
•
Standby mode
•
Sleep mode
