Windowsでディスクを修復する
created: 2025-01-17
Windowsでディスクのチェックと修復をしてみました
chkdsk | Microsoft Learn が参考になります
chkdsk
コマンドプロンプトでコマンドを実行してやります
Windowsの検索窓で cmd とうったりしてコマンドプロンプトを見つけ、管理者として実行を選びます
今回チェックしたかったのはOSも入っているCドライブだったので、以下のコマンドを実行しました
chkdsk c: /r/r で物理ディスク エラーの追加分析を含む
/f の機能が含まれているので、/r で十分です
OSが動いているドライブだったため、再起動後にチェックが始まりました
ブート画面でチェックが始まり、進捗が表示されます
1時間くらい放置したら終わっていました
結果を確認
Windowsが起動したら結果を確認します
chkdsk | Microsoft Learn のイベントビューワーの指示通りに開いてみました
結果を貼り付けてみます

</Event>こんな結果でした
ChatGPTに結果を評価してもらったら
総合的に見ると、ディスクの物理障害はなく、MFTビットマップの割り当て情報に不整合があったのを自動的に修正した、という内容です。
最終的に「No further action is required.」とある通り、現状では特に追加の対処は必要ありません。
引き続きバックアップをこまめに取りつつ、異常な動作が出ないか観察しておくと安心です。と問題なさそうです
まとめ
ディスクが壊れると面倒なのでおかしいと感じたらチェックしておきたいです
