open Hard Disk Drive - showing Head Crash

Try to compare it with one of those old LP records: imagine you're playing a song and moving the record player which is like moving a running laptop when it's reading/writing on the hard drive. Just one little hit and you might have a crack in your LP record. If that's not sooo big you won't even notice it on a hard drive because the electronic takes care of it by trying to avoid that section.
