投稿したSMARTデータには、ドライブが故障に近いことを示すものは何もありません。

このレポートをさらに詳しく見ていきましょう。 SMARTが重大な「データ損失が差し迫った」タイプの問題を検出しなかったことを示す最初の兆候は、次のとおりです。

=== START OF READ SMART DATA SECTION ===
SMART overall-health self-assessment test result: PASSED

SMARTが差し迫った障害と見なされた場合、全体的なヘルス自己評価テストの結果はPASSEDではなく、もっと不吉なものになります。

SMART属性テーブルにスキップして、WHEN_FAILED列に何も含まれていないことに注意してください。つまり、現在(またはこれまで)、正常なしきい値を超える属性値が検出されていないことを意味します。値がクリティカルしきい値を超えた(または超えた)場合、null値(ハイフンで表される)の代わりに、FAILING_NOWまたはIN_THE_PASTのようなものが表示されます。

とはいえ、必ずしも健康的なSMARTレポートを、ドライブが故障しそうにないことを100%証明するものとして報告する必要はありません。どのタイプのドライブも、いつでも突然故障する可能性があります。問題の兆候がSMART属性に表示されるずっと前に。言い換えれば、適切なSMART属性レポートを証拠絶対的なドライブではなく、健全なドライブ証拠データが失われてはならない場合は、適切なバックアップ戦略が必要です。
