破損したUディスクは消え続け、修理作業を実行できません。

破損したUSBフラッシュドライブを修復しようとしています。これは新しいUSBフラッシュドライブであり、同僚が暗号化を試みた後に動作が停止しました。残念ながら、暗号化がどのように壊れたかはわかりませんが、その過程で重要なデータ（パーティションテーブルなど）が壊れたと推定されます。

---

これを挿入すると、システムはその項目を見つけてlsusbその出力に表示しますlsblk。

ddただし、何かを実行または実行badblocksしようとすると、mkfsこれらすべてのコマンドは最終的にI / Oエラーのために失敗します。この場合、ペンドライブはlsusbまたはの出力にも表示されませんlsblk。だから私はこのプロセスでOSが何とかペンドライブを切断したと仮定します。

接続を維持するにはどうすればよいですか？
