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.

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.
