Physical/electrical specifications

This section provides information relating to the physical and electrical characteristics of the drive.

PowerChoice

power management

Drives using the CSS architecture have limited power management capability.

The table below lists the supported PowerChoice modes. The further you go down in the table, the more power
savings you get.

PowerChoice modes

Description

Idle_A

Reduced electronics

Idle_B

N/A

Idle_C

N/A

Standby_Y

N/A

Standby_Z

Motor stopped (disks not spinning)

PowerChoice

can be invoked using only the Start Stop Unit command for drives using the CSS architecture:

• START STOP UNIT command method—Use the START STOP UNIT command (OPERATION CODE 1Bh).

This allows the host to directly transition the drive to any supported PowerChoice mode.

The REQUEST SENSE command reports the current PowerChoice state if active and also the method by
which the drive entered the PowerChoice state.
