ERROR_CORRUPT_LOG_OVERFULL

a volume corruption log is full and cannot record additional findings.

ERROR_CORRUPT_LOG_OVERFULL indicates this condition: Windows maintains metadata that tracks detected file-system corruptions and pending remediation. When that log reaches capacity, newly detected problems may go unrecorded, so the visible entries are no longer a complete inventory of volume damage.

Where the result appears

  • NTFS or ReFS health monitoring.
  • online scan and self-healing infrastructure.
  • storage dashboards reading file-system health.
  • maintenance tasks that defer repair while corruption records accumulate.

What to collect

  • volume identity, file-system type, and current health state.
  • existing corruption records and the time the log became full.
  • scan, scrub, repair, and chkdsk history.
  • free space and any repeated I/O or metadata errors.

Handling and recovery

Schedule a full supported scan and repair rather than clearing the symptom alone. Preserve logs, back up valuable data, and verify the volume after repair because corruption detected after the log filled may not have been tracked.

Common misinterpretation

Deleting or clearing a full log does not repair the underlying file-system damage and may remove the only list of known corruptions.
