Statement CAM status: Uncorrectable parity/CRC error

  • I installed pfsense.

    Everything works fine, but the following message appears from time to time.

    Sep 3 12:28:21	kernel		(ada0:ahcich0:0:0:0): WRITE_FPDMA_QUEUED. ACB: 61 00 4f 04 81 40 08 00 00 01 00 00
    Sep 3 12:28:21	kernel		(ada0:ahcich0:0:0:0): CAM status: Uncorrectable parity/CRC error
    Sep 3 12:28:21	kernel		(ada0:ahcich0:0:0:0): Retrying command

    From the content of the message I conclude that there is a problem with the disk.
    However, I am not able to determine what.
    Does anyone know how to fix the above error, the message is not popping up.

    Unfortunately that could be anything. It could be the drive itself, the cable, the port on the motherboard/controller, even drive firmware and not a hardware fault.

    Check Diagnostics > SMART Status, see if anything looks out of sorts there in the 'All' output for the drive. Maybe even initiate a test and see if it finds anything.

    If it's a SATA disk, swap the cable out and try a different SATA port on the motherboard.

    If that doesn't help, it probably is the disk.
