I have a Alienware M14X (Early 2011) which came with a Seagate 750GB Momentus hard drive. I replaced it with a Intel 520 SSD. After a clean install the ST Microelectronics DE351DL Free Fall Sensor is coming up as a Unknown Device in the Device Manager. My question is, is this driver compatible with the Intel 520 SSD or would it be better not to install it? I plan on upgrading to Windows 10 and I don't know if I can even find a driver for it. After doing a search people are having trouble finding Windows 8 drivers. Does anyone know what this driver actually does?
