STATUS_DEVICE_DATA_ERROR

The transferred data is not trustworthy

This status identifies a data-path failure rather than an unsupported command. Depending on the device class, evidence can include storage sense data, CRC or ECC failure, a malformed descriptor, or a controller-reported data-integrity condition. The operation might have reached the device and still returned unusable content.

Preserve class-specific error information before retrying. Repeated reads can succeed after internal recovery and hide a degrading medium or link. Compare failures by logical block, transfer size, cable or port, and device telemetry. Never assume that successful completion of a later retry proves the original data was correct.

What to inspect

  • Capture sense data, protocol status, residual length and affected offset or block.
  • Check device health telemetry and controller event logs for corrected and uncorrected errors.
  • Validate critical data against an independent copy or checksum before continuing.
