    Default What is zero gravity sensor in Gateway Tablet?

    I notice there is 7200rpm 80GB HD option with zero gravity sensor for Gateway Tablet both C-120X and C-140X small business version. I didn't have that option when I purchase S-7125C (the small business version of C-120X) a couple months ago. Does anyone have any idea what is it?

    My wild guess would be a shock sensor just like the Fujitsu's tablet and Lenovo's tablet. If that is true, I hope it can be added to our existing tablet.

    It sounds like a sensor that detects the computer falling and returns the hard drive head to a standby position to prevent damage to the drive. I'm no expet on hdd construction though, so I'm probably calling things by the wrong name.

    A simple google search:
    http://www.patentstorm.us/patents/7199969.html
    A shock protection apparatus which includes a zero-gravity sensor for detecting whether a hard disk drive is in a zero-gravity state. Upon the detection of a zero-gravity state, the zero-gravity sensor generates a zero-gravity detection signal. Subsequently, a head-slap sign detector outputs, to the hard disk drive, a signal for retracting a head if the hard disk drive is determined to be in the zero-gravity state as detected by the zero-gravity detection signal. In the shock protection apparatus, the influence of change over time of a shock-cushioning material is reduced, the difference in shock-resistant performance between operating and non-operating states is reduced, and signs of a head slap are detected promptly and properly so as to urgently retract the head.

    Thanks!

    The sensor sounds useful to me because it would protect my harddrive (hence my data) when there is sudden acceleration and I imagine it could be used for auto-rotation and other stuff too if someone can write a software taking advantage of this sensor. What's your opinion? Is it useful?

    Also, is it possible to add this sensor to my current S-7125C? Is this part of the hard drive or is it an additional piece of hardware? Does anyone have their Gateway tablet (either C-120X or C-140X) equipped with this sensor? I wonder how good Gateway implement this sensor versus other tablet that has this sensor.

    These sensors are included in some hard drives. I would recommend swapping out your hard drive before you try anything further.
