Operating Basics 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 Utilities 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.
