FVE_E_TOO_SMALL

FVE_E_TOO_SMALL means BitLocker cannot proceed because the target volume lacks sufficient free space. The exact requirement depends on the volume and operation, so inspect the actual conversion state rather than assuming a fixed threshold.

What to check

  • Verify free space, the selected encryption mode, and whether conversion had already started.
  • Remove only unneeded data or extend the volume through a supported storage workflow.
  • Do not interrupt an existing conversion to free space without first checking its state.
