Hello all, I happen to have reinstalled by mistake a new Windows7 OS on a drive (I had two drives one with an OS and another with a bitlocker drive used for back up, both drives were IDE drives and the bitlocker was under slave mode if that can be of any help... ) that hosted VERY important data and was encrypted by Bitlocker.What can I please do to recover this formerly encrypted data? The drive is now recognized as an active healthy partition with an associated drive letter (different from the original one) I don't have the bitlocker key. If you need any hardware info please let me know. Help me please! Best, Mike

Hi, Its seems that you have formatted this bitlocker HDD, I am sorry for no much help to this case. But you can try to find the help from some professional data recovery company.Spencer TechNet Community Support
