After an unattended installation of Windows 7 Ultimate, it started to encrypt my separate data disk. The PC was very slow. Stopped bitlocker at 11.4 %. After reboot every thing looks normal, but I canâ€™t reach my data disk. If I resume or undo the encryption, I see the message â€˜no pathâ€™. The only thing I can do is a format. Please help.
