USBハードドライブからビープ音が鳴り始めた後、動作を停止しました。再動作するには、ハードドライブを再挿入する必要がありました。しばらくすると、同じ音が聞こえ、再び動作が停止しました。私のUSBハードドライブはTranscend StoreJetです。
USBハードドライブが死んでいますか？わからないので、以下にsyslog出力ファイルを追加しました。
ところで、私はUbuntu 12.04 Beta 2を使用しています。 Ubuntuのベータ版の影響によるのでしょうか？

Ubuntuのベータ状態がドライブの問題に関連しているかどうかは非常に疑わしいです。
ドライブに問題がありますが、ログ出力によると、問題が致命的であるかどうかを知る方法はありません。以下は、問題を表す関連行です。
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
これらのエラーが読み取りによって発生した場合は、物理ディスクセクタを上書きするだけでエラーを解決できます。停電により、セクタに誤ったチェックサムが記録されることがあります。その後、これらのセクタを読み取ると、チェックサムがデータと一致しないため、I / Oエラーが発生します。これらのセクタを上書きすると、チェックサムが変更され、そのセクタを再度読み取ることができます。私はこのようにして複数のドライブを修理しました。
ただし、物理ブロックに障害が発生したため、ドライブにそれを交換するためのスペアブロックがない可能性があります。この場合、ドライブを廃棄する必要があります。
今やるべきことは、交換用ドライブを購入し、問題のあるドライブからデータをコピーすることです。完了したら、不良セクタを上書きし、I/O エラーが消えるかどうかを確認できます。
