smartctl中的“Lifetime_Remaining%”是什麼意思？
最近我有一個
fsck error on boot，我不得不手動執行 fsck 。所以，我做到了，問題就消失了。之後我跑smartctl -a /dev/sda了，我看到了以下屬性ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE 201 Lifetime_Remaining% 0x0023 100 100 005 Pre-fail Always - 6什麼意思？這是我應該擔心的事情嗎？
我搜尋了其他類似的問題，但沒有找到答案。我的作業系統是 Ubuntu 20.04
這是 smartctl 輸出
