Parity check error


Recommended Posts

CRC errors are connection issues and the operations causing it normally retried recovered automatically.    Points to note are:

  • an occasional crc error is not something to worry about, although if the automatic recovery does not work you could get a read or write error so you do want to know they are occurring.
  • tye CRC error count never resets to 0 so you only need to worry if it keeps increasing
  • the commonest cause of CRC errors is the SATA/Power cabling to a drive.
