ERROR_DATA_CHECKSUM_ERROR

A checksum detected corrupted data

ERROR_DATA_CHECKSUM_ERROR means stored or transferred data no longer matches its integrity checksum. The error should be treated as possible corruption, not as a cosmetic validation warning.

Immediate actions

  • Stop overwriting the only copy of the affected data.
  • Retry from a known-good replica or backup when available.
  • Inspect disk, controller, memory, and transport health.
  • Correlate with file-system and hardware event logs.

Resolution

Restore the damaged data from a verified source and investigate the layer that altered it. A successful later read does not erase evidence of an integrity failure.
