Hitachi 100GB 7200 RPM HTE721010G9SA00 User Manual

Travelstar E7K100 (SATA) Hard Disk Drive Specification

96 

When the power save mode is Standby mode, the Idle command causes the device to enter Performance Idle mode 
immediately and sets the auto power down time-out Parameter (standby timer). At the set of the auto power down 
time-out parameter (standby timer) the point timer starts counting down. When the power save mode is already any 
idle mode, the device remains in that mode. 

When the Idle mode is entered, the device is spun up to operating speed. If the device is already spinning, the spin 
up sequence is not executed.

During Idle mode the device is spinning and is ready to respond to host commands immediately.

Sector Count 

This indicates the Time-out Parameter. If it is zero, the time-out interval (Standby Timer) 
is disabled. If it is other than zero, the time-out interval is set for (Time-out Parameter × 5) 
seconds.

The device will enter Standby mode automatically if the time-out interval expires with no 
device access from the host. The time-out interval will be reinitialized if there is a device 
access before the time-out interval expires.
