私はHDDのSMARTは、理想的には、以下または同様の形式で、（WMIまたはその他を使用して）を登録し利用できるようにそのコードを探しています：C＃WMI HDD SMART
レジスタ名 - 現在の値、最悪値を、しきい値、データ（ベンダ）、およびSMARTステータス。
私は、これまでのしきい値を提供していないか、標準のSMARTフィールド（すなわち現在、最悪、しきい値）の一つ以上が欠けていることがわかりましたWMIの実装の多くは。いくつかの作業の後
は、私が一緒にC＃/ WMIを使用してHDD関連するすべてのSMART情報の包括的な報告書を返すコードを入れています。
hereから引き出されるように、これはコードです：

/// Findings; I do not trust the individual smart register "OK" status reported back frm the drives.
/// I have tested faulty drives and they return an OK status on nearly all applications except HD Tune.
/// After further research I see HD Tune is checking specific attribute values against their thresholds
/// and and making a determination of their own (which is good) for whether the disk is in good condition or not.
/// I recommend whoever uses this code to do the same. For example -->
/// "Reallocated sector count" - the general threshold is 36, but even if 1 sector is reallocated I want to know about it and it should be flagged.

こんにちはAndrew、私はただ今すぐ対応する時間がありました。 私は単純なリンクだけの答えのたくさんを見るstackoverflowを見てください。私はこの場合も同じことをしており、問題は見られません。 第2に、自己宣伝に関するご意見について。私は他の人々が悩んでいることについて何も言わない。実際、誰も私の質問に答えを出してくれませんでした。私は自分の時間とお金で解決策をまとめ、世界と共有しました。 あなたの影響のようなコメントstackoverflow groupiesスイートに従って、良い答えを投票してください。誰も勝ちません。 – TheLegendaryCopyCoder
