UDMA CRC ERROR COUNT INCREASING

I have an unraid installation where after years of running it is now throwing a lot of these udma crc errors.  From looking around it seems that the likely culprits are the controller card or the cabling.  I am hoping to get some help identifying the issues.  I am attaching the diagnostics.  Thanks in advance.

    I would start by replacing the SATA cable for the affected disk(s).

    ... also worth checking the power cabling as that can also cause CRC errors.
