這個硬碟死了嗎？

不確定，這個 Q 的網站是否正確，但讓我試試

上次我的硬碟有問題。有時它會發出奇怪的聲音，我從日誌中得到它：

這個ata4 sata硬碟死了嗎？我必須盡快改變它嗎？需要我指定更多資訊嗎？

立即更換驅動器，尤其是當“奇怪的聲音”是咔噠聲時。

點擊當然是一個問題，但我發現這個問題正在調查我們伺服器上的類似錯誤，在我們的例子中，問題不是驅動器，而是 WD（Western Digital）和錯誤的 NCQ 實施的問題！

您可以在這些連結上閱讀它，看看它是否適合您的問題：

• http://www.axelog.de/2010/05/9-sata-phyrdychg-exception/
• https://bugzilla.kernel.org/show_bug.cgi?id=8627

但是錯誤（特別是這部分）看起來很相似，以至於我發現了這個問題:)

ata6.00: exception Emask 0x10 SAct 0x0 SErr 0x1810000 action 0xe frozen
ata6.00: irq_stat 0x00400000, PHY RDY changed
ata6: SError: { PHYRdyChg LinkSeq TrStaTrns }

對我們來說，短期修復/測試是這樣的：

echo 1 > /sys/block/sd{a,b,c,d}/device/queue_depth

長期將其添加到黑名單中，您可以在參考資料中閱讀。我沒有這方面的經驗，但連結 2 說更新檔看起來像這樣：
