Protection. 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.
This function does not work when the computer is booting, in Sleep Mode,
in Hibernation Mode, in transition to Hibernation Mode, recovering from
Hibernation Mode, or powered off. Do not subject the computer to vibration
or impact while the function is disabled.
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.
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.
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.
