TOSHIBA HDD Protection - Shock Sensor Driver is a utility designed to work with Toshiba laptops that have a built-in accelerometer or shock sensor. This sensor detects sudden movements or impacts (such as dropping or bumping the laptop), and the driver helps protect the hard disk drive (HDD) by temporarily stopping the disk from spinning to prevent damage. It essentially acts as a protective measure, reducing the risk of hard drive failure due to physical shock.
