Spin down and do not 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.
Idle Immediate – 95h/E1h Idle Immediate – 95h/E1h Idle Immediate – 95h/E1h Idle Immediate – 95h/E1h 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 Standby – 96h/E2h Standby – 96h/E2h Standby – 96h/E2h 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.
Idle – 97h/E3h Idle – 97h/E3h Idle – 97h/E3h Idle – 97h/E3h Idle – 97h/E3h
Spin up and change time out value. This command will spin-up the spin motor if the drive is spun-down.
If the drive is already spinning, the spin up sequence is not executed. A non-zero value placed in the Sector
Count register will enable the Automatic Power Down sequence and their timer will begin counting down
immediately. A value of zero placed in the Sector Count register will disable the Automatic Power Down
sequence. The actuator is parked and some circuits are powered off.

This command returns a code in the Sector Count register that determines the current Power Mode status of
the drive. If the drive is in, going to, or recovering from the STANDBY MODE the drive sets the Sector
Count register to OOh. If the drive is in the IDLE MODE or ACTIVE MODE, the drive sets the Sector
Count register to FFh.
Set Sleep Mode – 99h/E6h Set Sleep Mode – 99h/E6h Set Sleep Mode – 99h/E6h Set Sleep Mode – 99h/E6h Set Sleep Mode – 99h/E6h
This command will spin the drive down and cause the drive to enter the SLEEP MODE immediately. If the
drive is already spun down, the spin down sequence is not executed.
Note: The only way to recover from SLEEP MODE is with a software reset or a hardware reset.
