If I reinstall Windows 7, will drives encrypted with BitLocker be accessible

Hi all,

I expect the answer to this is yes, but I have a machine with several partitions on it.
Two of these are used for data and are encrypted with BitLocker.
If I re-install Windows onto the primary partition, will the other partitions still be accessible (given the correct password!)

Referencing the following TechNet article, it essentially applies to your scenario also:

BitLocker Drive Encryption in Windows 7: Frequently Asked Questions

The pertinent quote is as follows:

Can I access my BitLocker-protected drive if I insert the hard disk into a different computer?

Yes, if the drive is a data drive, you can unlock it from the BitLocker Drive Encryption Control Panel item just as you would any other data drive by using a password or smart card. If the data drive was configured for automatic unlock only, you will have to unlock it by using the recovery key. If it is an operating system drive mounted on another computer running Windows 7, the encrypted hard disk can be unlocked by a data recovery agent if one was configured or it can be unlocked by using the recovery key.

Yes, and this sentence confirms it:
When running Windows 7, you will have access to any BitLocker-protected fixed data drives and the drive Windows Vista is installed on.


No matter that this article is related with Vista to Win7 upgrade.

BTW, I am also sure it will work as I am using BitLocker on my thumb drive and it works on each Windows 7 machine (that supports Bit Locker) without any issues.
The same policy is worth for fixed drives/partitions.
Glad to help!
