TOSHIBA HDD Protection Properties
You can change the TOSHIBA HDD Protection settings by using the TOSHIBA 
HDD Protection window. To open the window, click Start 
 All Programs 
 
TOSHIBA 
 HDD Protection Settings. The window can also be started from 
the icon on the Taskbar or from the Control Panel.
HDD Protection
You can choose whether to enable or disable TOSHIBA HDD Protection.
Detection Level
This function can be set to four levels. The sensitivity levels in which vibrations, 
impacts and their similar signs are detected can be set to OFF, 1, 2 and 3 in 
ascending order. Level 3 is recommended for better protection of the computer. 
However, when the computer is used in a mobile environment or in other unstable 
conditions, setting the detection level to 3 could result in frequent execution of 
TOSHIBA HDD Protection, which will slow Hard Disk Drive reading and writing. 
Set a lower detection level when the speed of Hard Disk Drive reading and writing 
is a priority.
Different detection levels can be set depending on whether the computer is used 
as handheld or mobile usages, or whether it is used in a stable environment such 
as on a table in the workplace or at home. By setting different detection levels for 
the computer depending on whether it runs with the AC power (desktop) or with 
batteries (handheld or mobile usage), the detection level automatically switches 
according to the power connection mode.
3D Viewer
This feature displays a 3D object on the screen which moves in according to 
tilting or vibration of the computer. When the TOSHIBA HDD Protection detects 
computer vibration the Hard Disk Drive head is parked and the 3D object disk 
rotation will stop. When the head is un-parked the disk will begin to rotate again. 
The 3D Viewer can be started from the icon in the task tray.
n
  This 3D object virtually represents the Computer’s internal Hard Disk Drive. 
This representation may vary from the actual number of disks, disk rotation, 
head movement, part size, shape and direction.
n
  This feature may use a large amount of CPU and memory on some models. 
The computer may become slow or sluggish when attempting to run other 
applications while the 3D Viewer is displayed.
n
  Intensely shaking the computer or other subjecting it to strong impacts may 
cause damage to the computer.
