SCSI Description
5-62 Maxtor Atlas 10K III
The Power Condition Page controls disk drive Power Management functions. Power
Management provides three sub-states of UNIT READY:
• ACTIVE: This is the state of highest power consumption for the disk
drive. A media access command is acted upon immediately by the drive.
• IDLE: This is a state of lower power consumption for the disk drive. A
media access command is acted upon after a delay of approximately one
second.
• STANDBY: This is the state of lowest power consumption for the disk
drive. A media access command is delayed by approximately 10 seconds
before being acted upon.
Note that in all three sub-states, the drive remains READY.
Table 5-78 shows the data format of the page. Table 5-79 contains a description of the
Power Condition Page fields.
