我最近購買了 5 個二手 SAS HDD，每個使用了大約 35 天。與購買新 HDD 相比，這很划算，但有點混淆，因為我最初以為它們是 SATA。經過一番調查，我購買了一個 RAID 控制器（將其用作 HBA），PERC H710。然而，安裝完所有內容後，我注意到這些 SAS HDD 在空閒時會產生奇怪的咔嗒聲。我發現五張包裝完好的磁碟不太可能都出現同樣的問題，特別是考慮到賣家的良好聲譽。我記錄了噪音以供參考：
離伺服器較近： https://www.youtube.com/shorts/DFqMGDFCObU
在另一個房間（牆的另一邊）： https://www.youtube.com/shorts/4jHKJnIhp2Q PS：從影片中聽到聲音可能會很困難，尤其是在某些 SATA HDD 正在運行的情況下。伺服器正在生產中，因此正在對其他 SATA HDD 進行讀取/寫入操作。
以下是有關其中之一的一些資訊：

以前有人遇到過類似的 SAS HDD 問題嗎？這是 SAS 的正常行為嗎？任何建議將不勝感激！
答案1
運行以下命令並等待其完成後，我們得到“已糾正的總讀取錯誤=1809673244”，並且驅動程式停止發出這些噪音。
smartctl -tlong /dev/sdX
完成後的輸出如下：
root@abc:~# smartctl -a /dev/sda
