BitLocker Recovery
By Sam Paul Edelman
Encrypted File System recovery (EFS) and Encrypted NTFS recovery may be needed if a hard drive crash happens or data becomes corrupted due to a virus, software and hard drive changes, BIOS changes or any other hardware changes occur. What would make one have to recover encrypted files or how would the files be encrypted in the first place?
Encrypting a hard drive of a computer so data cannot be accessed, without a password to decrypt the drive, has become available through BitLocker, a program created by Windows. With this program no one would have access your files if your removable drives, flash or external hard drives, or laptop were stolen unless they had your password. Windows first came up with this technology in Vista, but it was too complex with many limitations. With Windows 7 BitLocker has become easier to manage in password protecting your data.
If you were using BitLocker, what would be some causes which would need you do a BitLocker recovery? If the EFS protected drive is put into a new computer, any changes to the boot-up configuration of a computer, changes to the MBR, master boot record, and changing BIOS setting and how the computer boots up are just a few causes to perform a NTFS recovery. It BitLocker detects any of these changes it assumes there is a threat and will lock your computer so it won't boot up. What can you do then to perform a BitLocker recovery and be able to get back into your system?
If any of the above threats, or any other, happen then BitLocker will go into recovery mode. Windows will prompt the user for a recovery keys, or password. From there you would need to go into the active directory and enter the recovery key in the prompt. After that you would log into Windows and suspend BitLocker protection mode. Restart your computer and go directly into the BIOS settings to make sure it is set to start with your hard drive. Then exit allowing Windows to start. Go in and reactivate BitLocker mode. Shutting down and restarting will make sure it has taken affect.
Other programs are available for EFS recovery and NTFS recovery but with Windows 7 BitLocker recovery is the best to use. Always keep your encryption key in a safe place so if any threat cause your system to lock up you will be able to use BitLocker recovery and get back going by entering your key.
