Current_Pending_Sector値は8回信号を1受信しましたError: UNC at LBA = 0x0bdec8ed = 199149805。 Ubuntu 18.04もbadblocks実行中ですが、エラーが発生します8/0/0。から199149800までのセクタ199149807は破損していると見なされます。
私はこれらのパラメータについて議論の余地があるいくつかの見解を読んだ。存在するこの回答たとえば、Current_Pending_Sector健康なディスクはそうではありません。増加する。他の人は、ゼロ以外のすべての値がディスクの交換を強くお勧めします。
- このドライブの状態はどれほど深刻ですか？
- 実行できる他の明示的なテストがありますか？

ハードドライブに不良セクタ（*）が8つあることは問題になりません。
不良セクタの数は時間の経過とともに増加すると予想されます。ゆっくり。
ディスクに書き込むと、コントローラは書き込みエラーを検出し、ディスク上の他のセクタにデータを書き込みます。ディスクチェッカーはまだ不良ブロックとしてマークされますが、そこには何も記録されません。だからあなたは本当に気にしません。
(*) 問題が発生する場所は、ブロックが失敗した場合です。後ろにが書かれています。これはアプリケーションで読み取りエラーとして表示されます。それから楽しみが始まります。バックアップから検索または再作成できますか？その場合、他のブロックに書き込まれます。それ以外の
場合は、ドライブにパフォーマンスの問題（読み取り/書き込みエラーなど）がない場合でも心配しないでください。年に数回不良セクタの数を確認してください。
読み取り/書き込みエラーによるパフォーマンス上の問題がある場合（注：これはシステムの速度がどれほど遅いかについての開発者/ユーザーの苦情ではありません）。不良ブロック数が大幅に増加したことを確認できます。これはディスクエラーを示します。
昔は許容できるほど悪い数値（総ブロックの割合）がありました（おそらく5％？）。その数が増加し始めた場合（最大8％？）、お金があり、ダウンタイムがある場合は、ドライブの交換を検討できます。
今日のドライブの信頼性が向上しました。一部のハードウェアメーカーは、ドライブに不良セクタがないと主張することもあります。 (ROTFL).
おそらく他の人が心配する不良セクタの数について良い数を持っているかもしれません。
IMHOディスクにエラーが発生しませんでした。まったく心配する必要はありません。
