Get-BitLockerVolume

  • Reference
Module:
BitLocker

Gets information about volumes that BitLocker can protect.

Syntax

Get-BitLockerVolume
   [[-MountPoint] <String[]>]
   [<CommonParameters>]

Description

The Get-BitLockerVolume cmdlet gets information about volumes that BitLocker Drive Encryption can protect. You can specify a BitLocker volume by drive letter, followed by a colon (C:, E:). If you do not specify a drive letter, this cmdlet gets all volumes for the current computer.

You can use this cmdlet to get BitLocker volumes to use with other cmdlets, such as the Enable-BitLocker cmdlet or the Add-BitLockerKeyProtector cmdlet. You can also use this cmdlet to view the following information about a BitLocker volume:

  • VolumeType - Data or Operating System.
  • Mount Point - Drive letter.
  • CapacityGB - Size of drive.
  • MetadataVersion - Returns the FVE metadata version of the volume.
    • 0 - Unknown - The operating system is unknown.
    • 1 - Vista - Windows Vista format, meaning that the volume was protected with BitLocker on a computer running Windows Vista.
    • 2 - Win7 - Windows 7 format, meaning that the volume was protected with BitLocker on a computer running Windows 7 or the metadata format was upgraded by using the UpgradeVolume method.
  • VolumeStatus - Whether BitLocker currently protects some, all, or none of the data on the volume.
  • Encryption Percentage - Percent of the volume protected by BitLocker.
  • KeyProtector - Type of key protector or protectors.
  • AutoUnlock Enabled - Whether BitLocker uses automatic unlocking for the volume.
  • Protection Status - Whether BitLocker currently uses a key protector to encrypt the volume encryption key.
  • EncryptionMethod - Indicates the encryption algorithm and key size used on the volume.

See BitLocker Overview for more information.
