enabled, the heads are parked and the spindle is at rest. The drive
accepts all commands and returns to Active mode any time disc access
is necessary.
Sleep mode. The drive enters Sleep mode after receiving a Sleep
Immediate command from the host. The heads are parked and the
spindle is at rest. The drive leaves Sleep mode after it receives a Hard
Reset or Soft Reset command from the host. After receiving the reset,
the drive exits Sleep mode and enters Idle mode with all current emula-
tion and translation parameters intact.
Standby timer. Each time the drive performs an Active function (read, write
or seek), the standby timer is reinitialized and begins counting down from
its specified delay times to zero. If the standby timer reaches zero before any
drive activity is required, the drive makes a transition to Standby mode. In both
Idle and Standby mode, the drive accepts all commands and returns to Active
mode when disc access is necessary.

1.8 Environmental tolerances

1.8.1 Ambient temperature

Operating 5° to 55°C (41° to 131°F)
Nonoperating –40° to 60°C (–40° to 140°F)
Note. Above 1,000 feet (305 meters), the maximum temperature is der-
ated linearly to 112 °F (44°C) at 10,000 feet (3,048 meters). Oper-
ating ambient temperature is defined as the temperature of the
environment immediately surrounding the drive.
