У меня есть ноутбук с твердотельным накопителем, и недавно он выдавал мне странные ошибки, и я не уверен, программный он или аппаратный. Поэтому я проверил мой SSD с помощью инструмента smartctl:
[root@laptop matthias]# smartctl -a /dev/sda

Я понятия не имею, как читать этот вывод. Все, что я вижу, - это старость и неудача. Мой SSD вот-вот выйдет из строя?
Я также управлял этим:
