"Won't happen". The 40,000 hours of runtime bug did happen. I would recommend people to take backups and store them offline or at least isolated from the main storage.
Sure, I plan for it but I do not expect it. And it never happened for me over decades. But I did plan for it, just not in the way the parent said and it did cost me far less.
Good to know ;) still think I am lucky; have had very little harddisks fail across 1000s. And only very few unrecoverable (had to restore from backup) failures; those weren't HD failures but software failures; hds were fine.
