UltraDMA CRC Error Count S.M.A.R.T. parameter indicates the total quantity of CRC errors during UltraDMA mode. The raw value of this attribute indicates the number of errors found during data transfer in UltraDMA mode by ICRC (Interface CRC).
This parameter is considered informational by the most hardware vendors. Although degradation of this parameter can be an indicator of drive aging and/or potential electromechanical problems, it does not directly indicate imminent drive failure. Regular backup is recommended. Pay closer attention to other parameters and overall drive health.
