新しいHDDが存在すべきではないエラーを一度に報告するとはどういう意味ですか?

マシンに複数の新しいHDDを取り付けたところ、そのうちの1つに2つのエラーが報告されていることに気付いたので、smartctl -xそれの上でこれを得ました:

ご覧のとおり、ドライブの電源投入時間は520(これは1か月も経っていないため正確です)ですが、2つのエラーは10610時間と16878時間に発生したと言っています。明らかに不可能です。

ここで何が起こっていますか?エラーは本当ですか?気になる?私のベンダーがここで何らかの「オドメーター改ざん」を行っている可能性はありますか?


更新

(私はもっと早くこれを持っていただろうが、 HGST Western Digital :/は本当に役に立ちません(OEMドライブにシリアル番号を与えないのに、それらの情報を保持しないのはなぜですか?)、また応答が遅いのです。)

これらをインストールしたとき、古いラベルのようにラベルに製造日が記載されていないことに気づきましたが、メーカーにそれ以上印刷せず、それ以上は何も考えないようにしました…私は Deltikの素晴らしい答えを見つけました。 これらは私には起こりませんでした。

メーカー(の新しい所有者)から公式のWordを取得する試みが失敗した後、私はそれらすべてを引き出し、フラットベッドスキャナーに最大設定で接続しました。古いズームとエンハンスを行うことで、それぞれが消去された証拠を見つけることができました。次に、読みやすい例の1つを示します。

あなたのよりイーグルアイドはおそらくすでにそれを読むことができますが、ここに自動レベルの長方形があります:

そう、そうです。すべてのドライブには、この意図的な詐欺の試みによる微妙な痕跡が残っており、それらはすべて2015年3月/ 4月/ 5月のものです。2018年11月末の「新しい」とは、まったく意味が異なります。

さらに、他のコメント投稿者の一部がそうであるように、SMARTはこのように転覆される可能性があります。リセットできれば、そのポイントのほとんどはなくなっていませんか?

私はこれをさらに追求します、私を信じてください。このスペースをご覧ください。

「走行距離計の改ざん」というあなたの疑惑は正しいと思います 可能です 。記録されたエラーは、読み取り時に不良セクターを示しているため、おそらく本物で間違いなく気になります。ディスクは、ユーザーに届けられる前に消去された可能性が高いため、これらの不良セクターはおそらく再マッピングされています。

ハードドライブを販売した人は、S.M.A.R.T.属性をリセットして、新しいハードドライブのように見せました。


逸話

2015年7月25日、非常によく似た6つのハードドライブをgoHardDrive.comから購入しました。すべてのディスクを確認したところ、ほぼ同じ症状が発生しました。

S.M.A.R.T.エラーがなければ、消去を忘れたか、消去できなかった場合、購入したディスクは新品であると確信していました。

疑わしいと思い、Hitachi Global Storage Technologiesに電話をかけたところ、2010年9月24日、少なくとも購入の5年前に少なくとも2つのディスクの保証が有効になっていることがわかりました。製造元の保証は3年後に有効期限が切れました。

私は売り手に不満を述べました。

S.M.A.R.T.属性値を消去することは、車の走行距離計をゼロにすることに似ています。S.M.A.R.T.属性を消去することの大きな問題は、私のようなエンドユーザーがセクターが再割り当てされているかどうかを識別します。再割り当てされていないセクターからすべてのスペアセクターが再割り当てされるまでの範囲が存在する可能性があります。これらのドライブは5年近く経過しており、73.7%以上の時間で少なくとも1つのドライブの電源がオンになっていることを考慮します。私が知らない可能性が高い再マップされたセクターです。

goHardDrive.comは少なくとも1台の故障したハードドライブを私に売却し、6台のハードドライブすべての動作履歴を故意に消去しましたが、販売時にハードドライブの使用状況を明らかにしていません。

ハードドライブの写真も撮りました。

Sketchy Hard Drives from goHardDrive.com – The hard drive at the bottom of the image is a reference drive.

イメージの下部にあるハードドライブは、同じ製造元の参照ディスクです。

参照ディスクにはAPR-2012印刷され、いつ製造されたかを示します。購入した6枚のディスクから製造日が削除されましたが、十分ではありません。かすかにわかる_ [中央のディスクを見てくださいAUG-2010

これは確かにディスクの履歴を確認します。「走行距離計」がリセットされた中古のハードドライブを購入しました。

結局、売り手は返品のリクエストを受け入れ、全額返金するためにすべてのディスクを送り返しました。

購入するハードドライブに注意してください!摩耗の跡が残っていないか確認してください。
