Operating Basics

Using the Hard Disk Drive (HDD) Protection

This computer has a function for reducing the risk of damage on the hard

disk drive.

Using an acceleration sensor built into the computer, TOSHIBA HDD

Protection detects vibration shocks and similar signs of movement of the

computer, and automatically moves the Hard Disk Drive head to a safe

position to reduce the risk of damage that could be caused by head-to-disk

contact.

When vibration is detected, a message will be displayed on the screen, and

the icon in the taskbar notification area will change to the protection state.

This message is displayed until the OK button is pressed or 30 seconds

pass. When vibration subsides, the icon returns to the normal state.

You can change the TOSHIBA HDD Protection settings by using the

TOSHIBA HDD Protection Properties window. To open the window, click

Start  All Programs  TOSHIBA  Utilities  HDD Protection

Setting. 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.

This function does not guarantee that the hard disk drive will not be damaged.

State Icon Description

hard disk drive head is in a safe position.
