I still have 820 Gb free by how much weight will my laptop per 100 Gb heavier?
No, nothing gets harder. The "free" 820gb are currently full of zeros, and if you store data on it, those zeroes will be replaced accordingly. So there's nothing to it, but it is only something existing changes.
Strictly speaking, the hard drive becomes ever easier with each writing. That's because the data is branded yes. Only when deleting then comes back to the extinguishing agent but this is much easier than silicone. In metal cutting, the plate becomes thinner and lighter.
Strangely enough, I read the same, nonsensical question pretty often here…
Since charges also have a mass, a plate that holds more charges (ones) is theoretically heavier.
But now it is so that firstly, the unrecorded area not only consists of blocks full of zeros, the assignment is aribiträr and secondly, data not only consist of ones, otherwise they could logically contain little information, in fact, the amount of positive charges more or less the same no matter how full the plate is.
So not only is it practically not measurable, but it also completely hunts theoretically how full your hard disk is.
