The error of my laptop, the HDD turned out to be the culprit. They tried to recover data, but it won't really work and I think they just pull me off my money, I can get them to wipe the HDD and make it useful again for 50 euro. I went Googling on solutions, DBAN could be a solution, what it does is forcibly write
x00 everywhere, but I'm not entirely sure whether it will be enough sufficient. HDD can't be attached by USB on Linux/Windows because it keeps just trying to load the drivers. In the topic also mentioned above, there's such thing as BoxyBox(?) or something like this.
Would it be possible of way to tell: "I don't care about your writing speed, your capacity, your name, your brand, anything, just write those x00 everywhere." ? Like I mentioned DBAN turns about to be a good guess, I'll try it out as soon as I land my hands on HDD, but, would there be no other solution but DBAN'ing it? I have no interest in recovering the data.
@edit - Maybe shorter: how to absolutely reset controller (to default), wipe out every type of data and all this kind of things, as close as possible to it original default values.
