相對較新的 WD Red Pro 產生 ATA 狀態：41 (DRDY ERR)，錯誤：FreeBSD 12.2 上的 40 (UNC)
我正在執行基於FreeBSD 12.2的****TrueNAS伺服器。我將儲存遷移到10 TB WD Red Pro。他們現在執行了 42 天。
突然，在 ZFS 清理期間，其中一個磁碟產生了 5 個錯誤。他們都或多或少地讀到：

我正在考慮對驅動器進行 RMA，但我不確定它是否符合 RMA 的條件。你怎麼看？這可能是一個暫時的錯誤嗎？任何建議表示讚賞。
非常感謝您的回复。根據你所說的，我決定將驅動器返還給西部數據。驅動器已經更換。
UNC表示UNC可糾正錯誤，這通常是由於中等錯誤（即：物理扇區壞了）。但是，您的 SMART 日誌顯示錯誤發生在 LBA 0x0。雖然理論上是可能的，但對我來說，您在該地址恰好遇到了讀取錯誤，這似乎很奇怪。報告的 SMART 待處理扇區 (0) 似乎證實了這一點，但我看到許多磁碟沒有正確更新該欄位。你能讀懂 LBA 0 嗎？請報告執行以下命令時發生的情況：
dd if=<your_disk> of=/dev/null bs=512 count=1 iflag=direct如果您可以成功讀取 LBA，則可能是您遇到了佈線問題，或者您的 HDD 的電子設備出現故障/不穩定。
