隨機 SSD 關閉 - ext4_find_entry ，讀取目錄 lblock0

從過去兩週開始，我在 GNU/Linux 中的 SSD 出現問題。我認為這不是設備問題，但我不確定。有時（最後幾天每 1-2 天）我會失去對磁碟的物理訪問權限，就好像它已斷開連接或斷電一樣。

錯誤：

EXT4-fs error (device: sda2): ext4_find_entry:1465: inode #1308161: comm NetworkManager: reading directory lblock 0

我從照片中輸入了這個錯誤，所以它可能不完全準確。

筆記：

設備總是相同的“sda2”，沒有註意到其他（大家庭）分區的錯誤。下次我會試著檢查一下。Inode 和程序名稱更改，但 NetworkManager 很常見。lblock 始終為 0。

硬體：

戴爾 E7270 帶SSD盤 LITEON CV3-8D512-11 SATA 512GB

軟體：

Debian 測試，核心 4.11。

想法：

• 執行壞塊檢查
• 檢查連接

我想我已經通過移除 SDD、將空氣吹入 M.2 連接器並重新插入來解決此問題。

當我從 USB 啟動以拯救 Debian 時，我注意到更詳細的核心調試資訊。在搜尋時，我注意到大多數解決方案都是更換 SATA 電纜。筆記型電腦 M.2 連接沒有電纜。

我要發畫面
