STATUS_FVE_CONV_WRITE_ERROR
What this BitLocker status means
The conversion workflow successfully reached a write stage but could not persist converted data or state. It is distinct from STATUS_FVE_CONV_READ_ERROR, where the required source data could not be read.
State to verify
Check the writable state of the target, available capacity, device and controller errors, storage virtualization limits, and any filter or backup operation that can interfere with writes. Preserve the BitLocker status and conversion context before making storage changes.
Recovery and confirmation
A recovery password does not fix a write-path failure. If an earlier conversion was aborted, the dedicated STATUS_FVE_CONV_RECOVERY_FAILED status describes failure to resume or recover that interrupted conversion.
