我的 USB 硬碟開始發出蜂鳴聲，然後停止運作。我必須重新插入硬碟才能使其再次工作。一段時間後，聽到同樣的聲音，它再次停止工作。我的 USB 硬碟是 Transcend StoreJet。
我的 USB 硬碟快不行了嗎？我不確定，所以我在下面添加了系統日誌輸出檔。
順便說一句，我使用的是Ubuntu 12.04 Beta 2。

答案1
Ubuntu 的測試版狀態與您的驅動器問題是否有關係非常值得懷疑。
您的磁碟機出現問題，但是根據您的日誌輸出，無法確定問題是否是致命的。這些是指示問題的相關行：
Mar 31 22:26:06 talk kernel: [13354.939177] end_request: I/O error, dev sdb, sector 488459069
Mar 31 22:26:06 talk kernel: [13354.939344] end_request: I/O error, dev sdb, sector 488459180
如果這些錯誤是由讀取引起的，則可以透過簡單地覆蓋實體磁碟區來挽救它們。由於電源故障，磁區可能會寫入錯誤的校驗和。後續讀取這些磁區將產生 I/O 錯誤，因為校驗和與資料不符。覆蓋這些磁區將修復校驗和，並且讀取該磁區將再次運作。我已經用這種方法修復了幾個驅動器。
但也可能是實體塊確實發生了故障，並且您的驅動器已用完備用塊來替換它們。在這種情況下，驅動器應該報廢。
現在您應該做的是購買替換驅動器並從有問題的驅動器複製資料。完成後，您可以嘗試覆蓋壞扇區並查看 I/O 錯誤是否消失。
答案2
我以前經歷過這種情況，但你的問題可能有所不同。不管怎樣，如果我所做的對你有幫助那就太好了。
有些 USB 線很舊，無法傳輸足夠的電力來為更高要求的設備供電。有些 USB 連接埠很舊，無法傳輸足夠的電力。
我的硬碟配有 USB 線，有 2 個兩個頭可連接到電腦。在較新的 PC 上，我可以只使用帶有“較粗”電線的 USB 頭。在較新的 PC 上，我必須將兩個磁頭都插入計算機，一個用於數據傳輸，另一個用於傳輸 haddrive 開始更快旋轉時可能需要的任何額外電源。
您的 USB 線是否舊了？我想除非你把 USB 線混在一起，否則不會。你的電腦比較舊嗎？也許是 USB 連接埠本身無法為硬碟提供電力。
如果您可以將裝置插入「現代」電腦而沒有任何問題，那麼我將問題歸咎於 USB 連接埠。
硬碟將旋轉到需要消耗更多電力的程度，然後當它沒有獲得電力時，它會斷斷續續，發出嘟嘟聲，因為事情沒有按計劃進行，然後「重新啟動」並嘗試再次旋轉或閒置直到您重新連接它，具體取決於驅動器。
我可能完全錯了，但它發生在我身上。
