先週、Ubuntuの起動時間は約50秒から5分に短縮されました。
試してみましたが、dmesg次のメッセージがログに複数回表示されます。どうすれば解決できますか？

そのドライブが死んでいるようです。奇妙なサクサク音も出ると思います。 （ドライブがデータを再読み込みしようとすると、ヘッドが繰り返し移動するために発生し、修正不可能なエラーなしでは読み取ることができません。）
できるだけ早くドライブから個人用ファイルをコピーし、ドライブを交換してください。非常に迅速に失敗し、完全に動作を停止することができます。
ドライブがSMARTをサポートし、smartmontoolsがインストールされている場合は、それを実行してsudo smartctl -a /dev/sdaここで結果を報告できます。結果に応じて、長いオフラインスキャン（ディスクサイズによって1〜2時間程度）を実行してドライブの状態を正確に確認できますが、私の経験ではドライブが死んでいるようです。唯一の問題は、どれだけ早く完全に失敗するかです。
