Do not shout at your harddisk. Harddisk have feelings too. They feel hurt and depressed when you shout at them.
OK, I’m just kidding about harddisk having feelings. But really, do not shout at your harddisk. I was watching Security Now on TWIT and they were talking about this video.
The video is most likely real. And it is no surprise. We are putting more and more terabytes into a small harddisk. Even small vibration from sound might affect it.
So remember, do not shout at your harddisk. (Or shake it)
