STATUS_FT_WRITE_RECOVERY
A successful redundant write can still report a member failure
STATUS_FT_WRITE_RECOVERY is an informational recovery outcome. The fault-tolerant volume completed the write by writing a redundant copy after encountering a failure on one member, while reassignment of the failing area did not succeed. Application data may have been accepted even though the storage set lost healthy behavior on one path or member.
Fault-tolerant volume terminology in Windows explicitly centers on maintaining multiple copies that remain available after disk failure; Windows dynamic-disk documentation also covers mirrored and RAID-5 volume repair and reactivation workflows. Do not interpret the successful write result as automatic repair of the failed member.
Identify which copy contains the newly written data and the current state of the other members before forcing rebuild or replacement. Recovery actions that choose the wrong source can propagate stale data. The event timeline around the first write failure and the failed reassignment is more valuable than a later generic “degraded” report.
What to inspect
- The member that rejected the original write and the redundant member or copy that accepted it.
- Current mirror or RAID member state, synchronization state, and volume-management events.
- Controller or media errors explaining why reassignment failed and whether failures are spreading.
