Macintosh HDディスクに突然エラーが発生しました（システムが起動できなくなりました。diskotilがBツリーの問題について文句を言いました。過去にさまざまなdiskotilコマンドを試しましたが、成功しませんでした）。 ddrescueを使用して回復するには（現在はLinuxベースのコンピュータのみを使用しています） - 次のコマンドを使用してください。
ddrescue -f -r0 -n -d /dev/sdc /storage/macos.img /storage/macos_recovery.log
長い時間が経つにつれて今日の処理が終了し、非常に残念な結果が出ました。
これは、2012 MacBookに搭載された基本的な500GB HDD HFS +ディスクです。最初の行ではすべてがほぼうまく機能するので、そこにいくつかの重要なファイルを保存することができるようです（通常100kb未満なので、希望はありますか？）。 imgファイルで試したことは次のとおりです。
1 - 写真を撮ろうとしましたが、役に立たないtxtファイル以外には何も見つかりませんでした。
2 - testdiskを使ってみました。分割されていないディスクが報告され（どうせEFI GPTに設定されている）、どこでもランダムなHFS +パーティションが見つかりました。
3 - 現在gpartedパーティションの回復を試みています。
私の質問は次のとおりです。
- ディスクは500GB、出力imgファイルは931Gです。どうやってこれができますか？
- これらの損傷パターンの原因は何ですか？私はstackXサイトでさまざまなパターンを見たことがありますが（通常はリニアディスクの傷など）、このような規則的な波は見たことがありません。この問題は解決できますか？
パーティションマップを手動で再構築できるように、2012 MacBookディスクの元の情報をどこで見つけることができますか（例：回復HD / Macintosh HDパーティションの開始/終了位置に関する情報）。
- 混乱から回復する方法についての他のアイデアはありますか？
ありがとうございます！

ハードドライブが緑色のセクション（良好なセクタ）では騒音なしで完全に動作することを確認しましたが、不良セクタで奇妙な騒音が発生し始めました（繰り返し低く静かなノック音といくつかの高音の「古いハードドライブ」「読み取り」） ）騒音）昨日ディスクを開いてみると、ヘッドが停止位置に戻ってトッププレートが完璧に見えますね。
