Just deleting it is dangerous! How to "completely erase" disk data

2025/12/3 Edited to

... Read moreパソコンのデータ消去には、ただファイルを削除したりディスクをフォーマットしただけでは十分ではないことを、私自身の経験から強く感じています。なぜなら、削除やフォーマットだけだとデータの中身は物理的に残っていて、復元ソフトを使えば簡単に復元できてしまうからです。情報漏洩が怖い場合はこの対策は不十分です。 そこで「完全消去」の重要性を知りました。完全消去とは、ディスクのデータ領域に上書きを繰り返して、元のデータを復元不可能にする方法です。私が使った「Partition Assistant」ではゼロ書き、ランダム書き、さらに米国国防総省規格(DoD)やGutmann方式など複数の強力な消去方法が用意されていて、目的に応じて選べるのが安心ポイントです。 特にSSDの場合は独自の消去方式があるため、普通の上書きでは消去が不完全になることもありますが、Partition AssistantはSSD専用の完全消去にも対応していて、これも私が実際に試して信頼できると感じました。 パソコンを処分・売却する前には必ずこうした完全消去を行い、個人情報の漏洩を防ぎたい方には本当におすすめの方法です。無料で使えるライセンスコードの取得方法など、詳細はぜひコメント欄で質問してみてください。私も皆さんの経験や疑問をシェアしながら、一緒に安全なデータ消去を目指したいと思います。
