1TbHDDを搭載した外付けUSB3.0ドライブに問題があります。私はそれを間違った方法でフォーマットしました:私は/ dev/sdb1の代わりに/ dev/sdbを書きました、そして今私はこのドライブを使う能力がありません。
fdisk /dev/sdb
fdisk: unable to read /dev/sdb: Input/output error
先週の土曜日、私はddコマンドを使用してsdbデバイスをゼロで書き込みました。これでプロセスは終了しました(2台目のPCでこのコマンドを1週間実行します)。しかし、私はddで1つの興味深いものを見つけました。 count = 1に設定すると、次に表示されます。
bs=512 - Input/Output error
bs=1024 - Input/Output error
bs=4096 - Okay!
しかし、私が試したすべてのことは成功しませんでした。 sfdiskは、IOエラーがあるとも言っています。
HDDはUSBアダプターなしでSATAに接続されています。
私がしたこと...
私はsfdiskを試しましたが、ddがすべてのディスクと他の多くのディスクをいっぱいにするまで待ちます...

4kセクターの書き込みが可能で、HDDが正常に動作する場合は、512バイトセクターをエミュレートする可能性のないネイティブ4k HDD( 高度な形式 と呼ばれることもあります)であることを意味する場合があります。私はまだそのようなドライブを見たことがありません。私が使用したすべてのドライブは512セクターをエミュレートできましたが、アクセスが調整されていないため、実行速度が少し遅くなりました。
HDDが読み取りを開始し、すぐに中止されないかどうかをdd if=/dev/sdb of=/dev/null bs=1m
で確認する必要があります(1m
は4kの倍数です)。 dd
コマンドが正常に実行される場合は、4kドライブのようです。このようなHDDにアクセスする場合は、4kセクターへのアクセスを調整できるツールが必要です。
見た目からすると、ディスクは死んでいて死んでいると思います(または最初から故障していたのかもしれません)。パーティションの代わりにデバイスをフォーマットすることはこれを行うことができないはずです、(データとは異なり... :)デバイスに損傷を与えることなく、私にも数回起こりました
同様のディスク、2TBの外部USB3 Seagateがあります。比較のために、smartctlの出力を投稿します。とりあえず、拡張セルフテストを実行してみます(gui GSmartControlまたはsmartctlのいずれかを使用します。ドライブには約6時間かかりますが、約半分になるはずです)。

IMHOAFAIK、これはhwエラーであり、ディスクは完了しています。恐れ入りますが、それでも拡張オフラインセルフテストを実行します。たまたま保証期間中ですか?
