Help with Bitlocker

I was switching to 64 Bit from 32 Bit and had a western Digital 1-TB hardrive, as a back up and was Bitlocker Encryption to . Saved all my files to this drive and turn of Bitlocker. When I set up Windows 7 Ultimate 64 Bit and added my back up drive it ask me to unlock well I would only the file with the key is on my back up drive which is Bitlock . Do you think its because its now 64 Bit and if I was to change back to 32 Bit do you think I could get back into this lock drive even with no key. Or if I was to to a quick format say 1 to 2 mins could I then get into the files on this drive.

Welcome to the forums Windowsjunky!

Should make no difference of which bit version! I have bitlocker on my 32 bit Windows 7, my 64 bit, and the devices work in either machine.

Or wait you dont have a password, you have a stored key? If you have the key on the drive thats encrypted that could be messy...

Step 1: Gather required materials
Obtain the following items to help you recover encrypted data from the affected volume:
1. The drive on which the damaged volume is located. This is the drive that contains the encrypted volume that you want to repair.
2. The recovery password or the recovery key for the encrypted volume. This is the recovery information that you saved when you enabled BitLocker.
3. An external hard disk. Use this drive to store the recovered data. This drive must be at least as large as the drive from which you want to recover the data.
Caution All the data on the external drive will be removed when you perform the recovery operation.
4. A USB flash drive. Use this storage device to store the BitLocker Repair Tool files. You can also store recovery information on this drive.
5. The Windows Vista DVD. This enables you to start a command prompt.
Note The edition of Vista on the DVD and the installation of Vista on the computer must be the same.
Step 2: Download and install the BitLocker Repair Tool
Download and install the Bitlocker Repair Tool that is appropriate for the recovery DVD that you plan to use. When prompted, click Accept to accept the license terms.
Step 3: Copy the BitLocker Repair Tool files to a removable device
After installation, copy the following files to the root of the removable device, such as a USB flash drive that will be used for the recovery:
%windir%\system32\bderepair.dll
%windir%\system32\repair-bde.exe
Also, create a folder named en-US in the root of the USB flash drive, and copy the following file to it: %windir%\system32\en-US\repair-bde.exe.mui
Step 4: Open a Command Prompt window
1. Use the Windows Vista DVD to start the computer.
2. Select the appropriate language settings, and then click Next.
3. At the bottom of the Install Windows page, click Repair your computer.
Follow the steps until you receive the option to click Choose a recovery tool, and then click Command Prompt.
Step 5: Determine which drives are present
1. Verify that all the appropriate drives are connected to the computer. These connections include the external drive to which you want to copy the recovered data and the USB flash drive on which the BitLocker Repair Tools files are located.
2. At the command prompt, type diskpart, and then press ENTER.
3. At the diskpart prompt, type list volume, and then press ENTER.
