Sounds like a failing HDD, if a jerky movement generates errors. Not sure about protection stuff, sounds like a proprietary Sony thing.

No it does not generates any error but I was just asking because I have seen hard disk protection software in windows.
Even in dell,toshiba and all...

Sorry, but you have been fooled by marketing, There is no hard disk drive protection software. The only think that it does is monitoring SMART error messages from the harddisk. This feature is built into the Ubuntu Drive Manager. But it does not help to protect your disc in any way.

Modern notebook HDD have a complex system for sensors, magnet and motors to react on any physical problem. This is ultra fast and reacts within microseconds. A software would need far to long to prevent anything. If the HDD sensed that the head is shortly before chrashing on the disc and notifies the software, the head will be crashed before the software has even received the message.

But companies like to install "disk protection software" and advertise it, because people think it will be helpful and buy it.

Thank You Sir!(thkrueger) your answer I think you are right ....I always doubted the companies but now you have explained it
well to me
Thanks Again

Thanks Thomas Krüger, that solved my question.
