我嘗試重新啟動 18.04 LTS 機器，但它沒有響應，因此等待幾分鐘後我重新啟動機器。
機器啟動正常，但我發現一些最近編輯的檔案現在是空的。這適用於至少 5 個已知案例，包括文字檔案、系統檔案和 .git 資料夾深處的檔案。
- 該檔案系統是否已嚴重損壞且使用不安全？
- 我如何知道這是否是硬體問題？
- 這是重啟 ubuntu 時已知的風險嗎？
其他資訊：
- 磁碟是三星970 Pro
- Ubuntu 安裝在 Ext4 分割區上（與 Windows 雙啟動）
Disks無法修復啟動磁碟（正忙）需要一個可用的 USB 記憶棒smartctl報告如下：
更新
- 運行時
sudo touch /forcefsck;sudo shutdown -r now沒有明顯檢查磁碟 - 使用活動磁碟，
Disks檢查分割區未損壞 fsck -f /dev/nvme0n1p5從活動磁碟運行不會回傳錯誤，退出代碼 = 0
