最近、Ubuntu が私の SSD がダメになったと言ってきました。このコンピューターは、この特定の SSD を搭載した約 4 年間を含め、約 10 年間動作してきました。このメッセージは、スタンバイ モードから復帰した後に表示されました。
Smartctl はこう言っています:

ご覧のとおり、私の SSD は 821 年間動作し、159 ゼビバイト (速度 6762 ギガバイト/秒) を保存し、約 100 回故障するはずです。しかし、すべて正常に動作し、わずか 4 年間しか動作しませんでした。
なぜそうなるのでしょうか、そしてどうすればいいのでしょうか?
UPD: 実際には数日後に死亡しました。
UPD2: 数日後にまた復活し、まるで新生児のような気分です。
