パーティションテーブルが失われましたが、パーティションの1つがNTFSとしてフォーマットされました。 （他のエラーのため）機能しませんが、次のようにファイルシステムツリーを復元できますtestdisk。parted回復ビット。残念ながら、このプログラムは、$ MFTという名前の一部のファイルと、$で始まる一部のファイルを除いて、まだ圧縮されたデータを回復できません。
それでは、この情報を組み合わせて、この情報で新しいntfsファイルシステムを初期化してデータへの基本アクセスを有効にすることは可能ですか？ファイルシステムツリーは完全であり、以前と同じです。

答え1
残念ながら、このプログラムは、$ MFTという名前の一部のファイルと、$で始まるいくつかのファイルを除いて、まだ圧縮されたデータを回復できません。
RecuperaBitを作成しましたが、NTFS圧縮で保存されたファイルが読み取れないことを確認しました。例外はないことに注意してください。$MFTデフォルトのファイルテーブルを保持するファイルです（すべてのメタデータファイルはこのテーブルで始まり、圧縮されませ$んが、一部は希薄です）。
あなたの目標：
データへの基本アクセスを有効にするには、これらのファイルシステムを使用して新しいntfsファイルシステムを初期化します。
MFTが実際に破損している場合は実現できないようです。ただし、そうでない可能性があることに注意してください。 16進ダンプでは、最初の項目（最も重要な項目）が正しく表示されます。おそらく、次も良いでしょう。
パーティションテーブルを復元し、少なくとも1つのNTFSブートセクタを選択するだけです。通常、バックアップブートセクタはドライブの端に配置されているため、簡単に復元できます。
出力にはファイルシステムの正確なサイズが表示されます。番号はブートセクタから読み取られるので、まだそこにあることがわかります。
Partition #0 -> Partition (NTFS, 1.82 TB, 4706 files, Recoverable, Offset: 2048, Offset (b): 1048576, Sec/Clus: 8, MFT offset: 6293504, MFT mirror offset: 2064)
Testdiskをドライブの100％で実行すると、パーティションが見つかります。その後、Testdiskを使用してファイルを一覧表示および抽出できます。バックアップされたNTFSブートセクタを復元することも、パーティションの最初のセクタにフラッシュして手動で復元することもできます。
