Hello, i have encrypted a partion of my harddrive using bitlocker. Caused by other reasons I had to reinstall Windows 7. After that the encrypted partion was empty and the bitlocker console stated this partition is not encrypted. Therefor I wanted to decrypt the partition using repair-bde. However, the result was not satisfying. The tool works well, the restore key is accepted and I do not receive any error -but: If the Outputvolume is another harddisk connected via USB I can not access the disk afte decryption. Windows tells me, the disk is not formated. Therefor the suggested chkdsk command does also not work. Here my input and the reulst from the Command window: C:\>repair-bde y: f: -rk c:\Bitlocker\70F0ED8B-16A9-4F92-BDE2-85298CF8FA26.BEK -force BitLocker Drive Encryption: Repair Tool version 6.1.7601 Copyright (C) Microsoft Corporation.

CHKDSK aborted. I tried to decrypt into an image file which also seems to work fine (no errors) but if I want to open or use the image file I still receive an error. Any suggestons, what I can do to decrypt my drive? Michael

Looks bad as you do not have a backup. I have looked into this problem time and time again. Bitlocker is not a backup drive When you installed Windows over, the partition tables changed My MVP is for the Windows Desktop Experience, i.e. Windows XP, Vista and Windows 7 IT Remote Assistance is available for a fee.
