Les structures NTFS, la table des fichiers, les enregistrements de r\u00e9pertoires : tout cela se trouve chiffr\u00e9 au m\u00eame titre que les fichiers eux-m\u00eames. La structure des fichiers ne peut \u00eatre reconstruite tant que les donn\u00e9es demeurent chiffr\u00e9es; il nous faut donc la cl\u00e9 avant m\u00eame que la reconstruction ne d\u00e9bute, et non pas seulement \u00e0 la toute fin, lorsque les fichiers sont restitu\u00e9s.<\/p>\n<p>L'outil de r\u00e9paration de Microsoft lui-m\u00eame fonctionne de la m\u00eame mani\u00e8re. La commande repair-bde a \u00e9t\u00e9 con\u00e7ue pr\u00e9cis\u00e9ment pour r\u00e9cup\u00e9rer des donn\u00e9es \u00e0 partir d'un volume BitLocker endommag\u00e9, et elle ne s'ex\u00e9cute pas sans un mot de passe de r\u00e9cup\u00e9ration valide ou une cl\u00e9 de r\u00e9cup\u00e9ration valide. Si les m\u00e9tadonn\u00e9es BitLocker du volume sont corrompues, un package de cl\u00e9 de sauvegarde devient \u00e9galement
