Description:
  Attempts to repair or decrypt a damaged BitLocker-encrypted volume using the
  supplied recovery information. If BitLocker was in the process of encryption
  or decryption or had been suspended prior to volume failure a clear key will
  be present on the volume. Repair-bde attempts to use this clear key by
  default if another key is not specified.

  WARNING! To avoid additional data loss, you should have a spare hard drive
  available. Use this spare drive to store decrypted output or to back up the
  contents of the damaged volume. 

Parameters:
  InputVolume
                The BitLocker-encrypted volume to repair.
                Example: "C:",
                         "\\?\Volume{26a21bda-a627-11d7-9931-806e6f6e6963}".

  OutputVolumeOrImage
                The volume to store decrypted contents, or the file
                location to create an image file of the contents.
                Examples: "D:", "D:\imagefile.img".
               
                WARNING! All information on this output volume will be
                overwritten.

  -rk  or -RecoveryKey
                Provide an external key to unlock the volume.
                Example: "F:\RecoveryKey.bek".

  -rp  or -RecoveryPassword
                Provide a numerical password to unlock the volume.
                Example: "111111-222222-333333-...".

  -pw  or -Password
                Provide a password to unlock the volume.

  -kp  or -KeyPackage
                Optional. Provide a key package to unlock the volume.
                Example: "F:\ExportedKeyPackage"
               
            If this option is blank, the tool will look for the key package
            automatically. This option is needed only if required by the tool.
	
  -lf  or -LogFile
                Optional. Provide a path to a file that will store progress
                information. Example: "F:\log.txt".

  -f   or -Force
                Optional. When used, forces a volume to be dismounted even if
                it cannot be locked. This option is needed only if required by
                the tool.
