Despre BitLocker Drive Encryption am mai scris in urma cu ceva timp. Atunci explicam cum putem cripta si parola o partitie a hard-disk-ului sau un memory stick / card de memorie, folosind acest nou feature al Windows 7.
Cei care utilizeaza BitLocker au observat probabil ca acest feature are un ceva lipsa. Ofera posibilitatea de criptare Und parolare a unui drive, posibilitatea de schimbare parola pentru deblocarea drive-ului, insa nu ofera nicio posibilitate de reactivare a parolei (re-lock drive) dupa ce drive-ul a fost deblocat. In mod normal, dupa ce deblocam drive-ul prin introducerea parolei, singura metoda de a reactiva parola este sa restartam PC-ul / laptop-ul. O optiune, un buton de re-lock drive sau orice altceva care sa ajute la reactivarea parolei, lipseste din setarile acestui feature.
Daca dorim totusi sa reactivam parola unei partitii criptate cu BitLocker fara sa restartam calculatorul, exista o metoda simpla, insa putin cam incomoda.
How to re-lock a drive (hdd partition / USB drive / memory card) with BitLocker.
1. Wir öffnen uns Eingabeaufforderung (CMD) cu user-ul de Administrator. (Run as Administrator)
2. In Command Prompt tastam urmatoarea linie de comanda:

“W:” reprezinta partitia / drive-ul pe care utilizam BitLocker si pe care dorim sa reactivam parola.
