Deskstar 7K80 Hard Disk Drive Specification

When Low RPM standby mode is the deepest Power Saving mode and the value in Sector Count register is
between 40h and 7Fh,

When Low RPM standby mode is the deepest Power Saving Mode and the value in Sector Count register is
between 01h and 3Fh,

where

x = the value in Sector Count register

y1 = the idle time to Low Power Idle mode

y2 = the idle time to Low RPM standby mode

If Low power idle mode has already been enabled (i.e., y1 has been set) before Low RPM standby mode is enabled,
y1 is preserved. If Low power idle mode is disabled (i.e., y1 has not yet been set), y1 becomes 120 seconds when
Low RPM standby mode is enabled.

Enabled Power Saving mode and idle time (y1 and y2) are preserved until Advanced Power Management is dis-
abled, the deepest Power Saving mode becomes Normal Idle mode, or a new time is set. They are initialized with
a hard/soft reset unless Reverting to Power on defaults is disabled and the devise receives a soft reset.

Additional electronics are powered off and the heads are unloaded on the ramp. The spindle is still rotated at the
full speed.

The heads are unloaded on the ramp and the spindle is rotated at the 60-65% of the full speed.

When Feature register is 85h (= Disable Advanced Power Management), the deepest Power Saving becomes nor-
mal Idle.
