現在書き込み不可能なHDDを扱っていますが、その理由がわかりません。この問題に関して私が観察した内容は次のとおりです。
読み取り専用ベンチマークを実行すると、読み取り速度とアクセス時間が良く見えます。
書き込みベンチマークを実行しても結果が出ず「停止した」ようです。
ディスクフォーマットを試みると、gpartedを含むディスクに書き込もうとするすべてのアプリケーションまたはプロセスが終了するまで中断されます。フォーマット試行のある時点で、「/dev/sdaへの書き込み中に入力/出力エラーが発生しました」が発生しました。私が見ることができるもう1つの明らかなエラーメッセージは、
Buffer I/O logical block <some_number> lost during async writeシャットダウン中に時々表示されるものと似ています。自己テストのSmartctl出力は問題ないようですが、これは物理的な問題ではない可能性があると信じています。
このコマンドは、
fdisk -l影響を受けたディスクに対して次の出力を返します。
Device Start End Sectors Size Type
/dev/sda1 63 532542 532480 260M EFI System
/dev/sda2 532543 498340557 497808015 237,4G Microsoft basic data
/dev/sda5 498341888 1953519615 1455177728 693,9G Linux filesystem
Partition 1 does not start on physical sector boundary.
Partition 2 does not start on physical sector boundary.
GPT PMBR size mismatch (4100491 != 15701758) will be corrected by write.
The backup GPT table is not on the end of the device. This problem will be corrected by write.
- ちょうどディスクから傷ついたような音がした。
したがって、特に6番目の項目がHDDに物理的な損傷を持っていると仮定しますが、もう一度smartctlがこれを指摘してくれることを願っています。残念ながら、私はこの種の問題の経験を持っていないので、ディスクが実際に破損していることを確認するために取ることができる追加の診断手順を知っている人に感謝します。
\dmesg編集：要求に応じて書き込みベンチマークを実行するときに出力をここに追加しています。ベンチマーク自体は、次のように最初のサンプルで停止します。

dmesg出力を見ると、ハードドライブが破損して回復できないことがわかります（ソフトウェアの観点から）。その中にデータが必要であると仮定すると、データ操作を中止することをお勧めします。
データが本当に必要な場合は、評判の良いリカバリ会社に連絡し、費用がかかる可能性があることに注意してください。
データが必要ない場合はダンプに捨ててください。
私はあなたの決定がより明確になることを願っています。
