私は放棄されたコンピュータからインポートされた古いSeagate 4TB内蔵ハードドライブをゲーム用のバックアップハードドライブとしてリサイクルする予定です。
安全のために最初にsmartctlスキャンを実行したかったので、そうしてsmartctl -t short /dev/sdb結果を得ました。 「WHEN_FAILED」列には何も表示されないため、問題はないようです（最初は主に温度関連のエラーに興味がありました）。ところで私は見た。2018年の記事 「Current_Pending_Sector」への言及はかなり深刻です。私のものはゼロではなくエラーもあります...気にする必要があるかどうかわからないので、SEを試してみるかと思いました。 。
これまで私の推測では重要な内容を入れてはいけないということです。しかし、保存フォルダをシンボリックリンクして他の場所に（より良い結果を得るためにドライブに）存在させて、もう一度気にしないと、ゲームで利用できるはずです。ドライブが失敗した場合は、インストールされたゲームをダウンロードしてください。また、「READ DMA EXT」エラーが差し迫ったエラーを示すのか、ケーブルやその他のワンタイムイベントであるのかはわかりません（エラー35-39のみが表示され、すべて「16936時間」に発生します...いいえ。すべてのエラー表示できる方法があるかどうか、または表示されているように最後の5つのエラーのみを保存することを確認してください。あるだけです）。
ドライブに寿命が少しでも残っている可能性が少しでもあれば、それほど重要ではないものに変えても大丈夫です。しかし、近い将来に失敗する可能性が高く、新しい磁石を購入する以外に時間を無駄にしたくありません。 :-) どのような提案/推奨事項がありますか？
とにかくまた走り、smartctl -t long /dev/sdb翌日まで待ったsmartctl -a /dev/sdb。結果は次のとおりです。

SMARTも悪くはありませんが、HDDファームウェアで解決できないいくつかのエラーがあります。
これで、どのセクタが破損しているかを正確に知っているので、ddを使用してそのセクタを再割り当てしてみることができます。

ただし、ドライブは現在安全に使用できないため、修理しても失われる可能性がある重要でない情報を保存するためにのみ使用することをお勧めします。
