hdapsd | HDAPS daemon for IBM/Lenovo ThinkPads | Mehr ...
This is a disk protection userspace daemon. It monitors the acceleration values through the HDAPS interface and automatically initiates disk head parking if a fall or sliding of the laptop is detected. . This daemon won't work out of the box on a stock Debian kernel, as it needs a patch, which is not in the default Debian kernels. Please read README.Debian for the source of that patch. . It is recommended that you use this daemon with the hdaps module provided by tp-smapi rather the one in the kernel, as this will save you a bit power and will work on a wider range of ThinkPads.
