Cache device shows SMART error (CRC Check)

On my 6.7.2 Array with a 2xSSD Cache Pool, one of the cache drives threw a CRC Error during a Mover run and I would like to know how to clear the warning.

 

I  had just manually transferred about 13Gb from my main PC to the backup share and clicked the Mover to distribute it all according to the share preferences and I got a popup saying that the first Cache drive had experienced one CRC Error.

 

Looking at the SMART Report for that device does show one CRC Error Count but all other values are healthy. A quick SMART test passes. The device is still flagged in yellow on the Dashboard and I would like to know if it can be cleared or if it is stuck that way?

To clear the dashboard warning click on the thumbs down and click acknowledge, CRC errors are a connection problem and usually caused by the SATA cable, though a single one is no reason for concern, but if you get any more replace the cable.
