to enter the STANDBY MODE immediately. If the drive is already spun down, the spin down sequence is
not executed.
Idle Immediate – 95h/E1h
Spin up and do not change time out value. This command will spin up the spin motor if the drive is spun
down, and cause the drive to enter the IDLE MODE immediately. If the drive is already spinning, the spin
up sequence is not executed. The actuator is parked and some circuits are powered off.
Standby – 96h/E2h
Spin down and change time out value. This command will spin the drive down and cause the drive to enter
the STANDBY MODE immediately. If the drive is already spun down, the spin down sequence is not
executed. A non-zero value placed in the sector count register will enable the Automatic Power Down
sequence. The timer will begin counting down when the drive returns to the IDLE MODE. A value of zero
placed in the sector count register will disable the Automatic Power Down sequence.

Count register to OOh. If the drive is in the IDLE MODE or ACTIVE MODE, the drive sets the Sector
Count register to FFh.
