It's fine, in the end, we lost nothing because for some god luck I had transferred all the projects on the second SSD the week before because someone told me to be careful about having stuff on the windows SSD. But because everything had to be reinstalled and repaired, it still took a week or so! To be frank, It was a very new and expansive computer, so I did not expect that at all. Even the repairer told me he had never seen a SSD died in less than a year, Guess I'm overworking it...
But I'll definitely be more careful now, thanks!
