FVE_E_TPM_NO_VMK

FVE_E_TPM_NO_VMK means that the TPM-based protector could not release the volume master key required to unlock the drive. The error can follow a TPM state, platform measurement, protector, or hardware condition.

How to investigate

  • Use a verified recovery method for the affected volume rather than assuming the encrypted data is lost.
  • Check TPM readiness and recent boot or firmware changes after access is restored.
  • Keep the recovery record and recovery key ID together when escalating the issue to device support.
