I encrypted my D: drive with bitlocker in windows 7. Saved BitLocker Drive Encryption Recovery Key file in a cd. I installed a new copy of windows 7. The encrypted drive is detected as a RAW Partition. I am not able to access that drive in the new OS. I have BitLocker Drive Encryption Recovery Key file and i have noted it manually . Data i encrypted is very important. I want my drive back. Can someone help me?

The best method would have been to temporarily unlock the drive when making changes to the computer. Did you create a complete pc backup (system image) to restore the old installation? Try click Start\Control Panel\System and Security\Manage Bitlocker and turn it on for D:\. Then try to unlock it.

Hi, You can use the Bitlocker Repair Tool with your recovery key to recover the disk. Please refer to the following link: http://technet.microsoft.com/en-us/library/ee523219(WS.10).aspx
